How to Share Notes from iBooks in iOS 11 and macOS High Sierra

It’s easy to take and share notes in iBooks for both iOS 11 and macOS High Sierra. Easy, that is, if you know how. So, let me show you how!

Firstly, I love taking notes in iBooks. I’d never desecrate a printed book with highlights, but I’ll do it all day long on an ebook. And Apple’s iBooks has the best ebook note-taking features that I’ve used.

Sharing iBooks Notes in iOS 11

iBooks started in iOS, and the ability to share or expert notes is a little better on iOS than it is in macOS High Sierra. Still, it’s not as intuitive or obvious as it should be, because you have to tap on “Edit Notes” before you can share. That is—in a word—frakking stupid. Make that two words.

Start with a note. Years before the Game of Thrones TV show, I figured out who John Snow was, and I did it, in part, thanks to the ability to take notes in iBooks. Every time I came across a reference to Rhaegar, Lyanna, the birthing bed, the bed of blood (hey, I didn’t write this stuff), and other references to Ned Stark’s early years and his sister, I highlighted them. The notes shown below are from Dance of Dragon, and deal mostly with Rhaegar and Lyanna.

To view all my notes in the book, I tap the table to contents icon, then the Notes tab at the top. That gives me a view like this:

Bryan's Notes from A Dance with Dragons

Now, tap the Share icon in the upper left.

You might think this would be how you share or export your notes. And it is, but there’s the stupid step to get through. You have to Tap Edit Notes > Select All, as shown below.

Edit > Select All in iBooks

All of my notes get a check mark from being selected, and the Share button lights up. When you tap Share, you get a new menu with one option by default, Mail, as shown below.

Tap the Mail icon, and an email sheet will open where you can decide where to send it.

That’s it!

Sharing iBooks Notes in macOS High Sierra

You can share notes from iBooks in macOS High Sierra, too, but it’s even less obvious. First, get to your notes by tapping the Notes icon. Click on a note to select it. If you then right click on the note (you can also just right-click to select in the first place), you get the option to Copy, or to share via Mail, Messages, Notes, Twitter, or Facebook, as shown below.

Here’s the bad news. You can only export/share one note at a time. While you can shift-click or option-slick to select multiple notes at one time, rick clicking on any of them deselects all but the one you’re right-clicking on. You’d have to share one note at a time and then copy-paste each of them into an email or other app to share them all at once.

Which is—in a word—frakking stupid. Make that two words.

But, at least you can share them.

How to Skip Converting to APFS When Installing macOS High Sierra

How to skip APFS when installing macOS High Sierra

MacOS High Sierra includes the all new APFS file system, which is arguably one of the most significant new features introduced in the new Mac operating system update. Nonetheless it’s possible that some Mac owners with SSD volumes will want to not convert the existing HFS+ file system to APFS file system when installing macOS High Sierra. With a little command line magic, you can skip converting to APFS during the macOS High Sierra installation process if desired.


How to Install macOS High Sierra Without Converting to APFS File System

This is not recommended and should only be applicable to advanced users who have specific reasons to not want to convert a Mac to APFS. APFS is faster and offers better encryption, amongst other benefits, so it’s generally recommended to use APFS if the Mac supports it. APFS is currently only supported on SSD drives, with Fusion drives support for APFS soon to arrive in a future Mac software update.

How to Not Convert to APFS During macOS High Sierra Installation

By skipping APFS conversion of file system, macOS High Sierra will install with the longstanding HFS+ file system instead.

  1. Download the MacOS High Sierra installer from the App Store as usual, making sure it’s within the /Applications/ directory*
  2. Open the Terminal application, found in /Applications/Utilities/ (or from the Utilities screen menu options if booted from a USB boot installer)
  3. Enter the following command syntax at the command line prompt:
    /Applications/Install macOS High Sierra.app/Contents/Resources/startosinstall --converttoapfs NO
  4. Hit return key to start the macOS High Sierra install process with the –converttoapfs NO directive, thereby skipping the APFS conversion of existing file system

* You will need the full installer to have the Contents/Resources/ options available to you. You can download the full macOS High Sierra installer with these instructions if you’re getting the little mini-installer without /Content/Resorouces/ folder.

In case you were wondering, skipping APFS can be achieved when running the High Sierra installer directly from Mac OS or when using a macOS High Sierra boot installer drive.

Mac users who ran the beta of macOS High Sierra may remember earlier versions of the beta builds had a toggle setting during installation to skip APFS conversion, but that option toggle is no longer available in the installer.

Regarding APFS and macOS High Sierra, Apple says the following on a knowledge base support article:

“When you install macOS High Sierra on the Mac volume of a solid-state drive (SSD) or other all-flash storage device, that volume is automatically converted to APFS. Fusion Drives, traditional hard disk drives (HDDs), and non-Mac volumes aren’t converted. You can’t opt out of the transition to APFS.”

Despite the Apple support article saying that you can’t opt out of the transition to APFS, it turns out that you can skip APFS if you choose to start the installer from the command line of Mac OS and give a directive to skip file system conversion. Outside of using the Terminal approach outlined above, or installing on an HDD or Fusion drive, there is no known other method to skip APFS.

Again, there is no benefit or particular reason for most users to skip APFS conversion. Skipping APFS file system on a Mac with a flash drive means the computer won’t see the potential performance boost offered by APFS with High Sierra. This is really only for advanced users who need to skip APFS for a specific reason, usually for networking or drive sharing compatibility purposes.

Pesky iMessage delay bug persists for some in Apple’s macOS High Sierra


 

A bug affecting a number of macOS High Sierra users can result in significant delays for receipt of iMessages and text messages, as well as a lack of notifications from an iPhone or Apple Watch for the same messages. At the moment, the only fixes appear to be disabling messages, or rolling back to macOS Sierra.

A number of users have detailed the issue in a growing thread on Apple’s support forums. In addition, one AppleInsider staff member also continues to have problems with the bug.

After updating to High Sierra, some users found that iMessages are significantly delayed in arriving on a Mac. In addition, while the Mac is active, notifications are silenced on other iCloud-connected devices like iPhones and Apple Watches.

The result means users may not receive texts and iMessages for hours after they are actually delivered.

Users posting in Apple’s forums found that certain actions can temporarily fix the problem, including disabling and re-enabling messages, or sending a message via the Mac. But the problems appear to return in time.

The only persistent fix users found was either disabling the receipt of messages on a Mac entirely, or rolling back the macOS install to the previous-generation version, Sierra.

In the interim, a community bug report for the problem has been created. But recent beta updates to macOS High Sierra do not appear to address the issues.

It has been speculated that the bug could be related to changes in High Sierra that will pave the way for iCloud syncing of messages. Messages in iCloud were featured in earlier betas of High Sierra and iOS 11, but the feature was removed at launch and is scheduled to debut in an update later this fall.

Messages in iCloud will seamlessly synchronize a user’s messages between devices. For example, deleting a message from one device would strike it from all other iCloud-connected devices.

Yes, High Sierra on Older Macs Really Does Boost Performance

Foks have been saying that installing macOS High Sierra on older Macs provides better performance, so I decided to test that theory. While my daily driver is Valtur, the TMO Hackintosh, I also have a mid–2010 Mac mini. From my testing, I can confirm that High Sierra provides a modest improvement in performance. Let’s look at how I compared Sierra with High Sierra.

high sierra on older macs

The mid-2010 Mac mini isn’t the pinnacle of computer performance, but it still fares better with High Sierra than the operating system’s predecessor

Testing High Sierra on Older Macs

Gandalf, my mid–2010 Mac mini, has an Intel Core 2 Duo P8600 processor and 8GB of RAM. The drive is a 256GB OWC SSD. I performed a clean install of macOS Sierra. I didn’t install any additional software, except for Geekbench 4 in Tryout mode.

After obtaining the Geekbench 4 results for Sierra, I downloaded and performed a clean install of macOS High Sierra. Then I downloaded Geekbench again, after the initial time of Spotlight indexing was finished, and ran another series of tests. Now for the scores – if you’re into geekspeak, keep reading the results. If you aren’t quite so interested in exact numbers, feel free to skip ahead to “Interpreting the Benchmarks.”

The Benchmark Results

As you’ll see in the charts below, macOS High Sierra performed modestly better in all categories. Regardless of whether the test was single-core or multi-core, High Sierra provided consistently better performance in the analysis.

High Sierra on older Macs

Single-core performance of Sierra versus High Sierra shows some improvement with the newer operating system

Under macOS Sierra, the single- and multi-core scores were 1063 and 1671 respectively. Using both cores, the Mac mini processed speech recognition tasks at 14.5 words per second, for a 1691 score. Face detection occurred at 770.3 Ksubwindows per second, leading to a score of 2637. Memory bandwidth was 3.41GB/second, getting a score of 639 according to Geekbench 4’s test parameters.

High Sierra on older Macs

Multi-core performance, too, improves in High Sierra compared to Sierra

By way of contrast, the single-core overall score for High Sierra on Gandalf was 1169. In multi-core performance, the Mac mini scored 1909, a 238 point difference. Speech recognition got a score of 2147, processing 18.4 words per second. Face detection scored 2682, a 45 point boost. The memory bandwidth with multiple cores was boosted to 3.8GB/second, for a score of 3616.

Interpreting the Benchmarks

Whew, those were a lot of geeky numbers and phrases. To make a long story short, High Sierra provides a modest performance boost for Gandalf, my mid–2010 Mac mini. This doesn’t surprise me too terribly much, since I’ve found the tiny beast to consistently perform slightly better with new versions of OS X/macOS.

While not surprising, it’s welcome to see. I enjoy the fact that I can continue to use a seven-year-old Mac with the most modern operating system, and not have to worry about it bogging down and becoming inefficient. These results, I think, lend credence to the reports others have made about macOS High Sierra on older Macs giving them better levels of performance.

Troubleshooting macOS High Sierra Problems

Troubleshooting macOS High Sierra problems

Are you having difficulties with macOS High Sierra? While most Mac users who update to macOS High Sierra have no issues with the system software, there are small groups of users who have experienced a variety of problems with the software update. This tends to happen with every major system software release, either due to compatibility issues, third party apps, bugs, or a variety of other reasons. This article attempts to gather a list of some of the reported macOS High Sierra problems, along with possible troubleshooting solutions to those issues, though by no means is this exhaustive.

There are mixed reports of some Mac users updating to macOS High Sierra and then experiencing a range of problems, from problems installing or downloading the installer, to rapid battery life draining, inability for some apps to open, apps crashing, strange performance problems or overall performance degradation, problems with mounting and reading disks, problems with networking connectivity and wi-fi, issues with graphics or displays, amongst a variety of other issues that can be frustrating. Dive in, and report your own experiences in the comments below.

MacOS High Sierra download fails

Some users report errors trying to download macOS High Sierra from the Mac App Store. If this happens, the first thing you should do is be sure your Mac is connected to the internet and has a functioning internet connection.

Often simply relaunching the App Store is sufficient to remedy a download problem as well.

  1. Quit out of the Mac App Store
  2. Relaunch the Mac App Store and try to download macOS High Sierra again

Rarely, you may need to reboot the Mac as well – this should not be necessary however.

MacOS High Sierra Installer is Incomplete or Unable to Make a USB Drive

Some users report they are unable to download the complete macOS High Sierra installer app, and instead wind up with a small 20mb version that attempts to download the remainder of the installer during the installation itself. This prevents the user from creating a USB installer for MacOS High Sierra.

A workaround for this issue is to use a third party tool to download the complete macOS High Sierra installer as discussed here.

MacOS High Sierra Installation Fails

If installation fails, usually in a very obvious manner with an error message when attempting to install the High Sierra update, the solution is usually to redownload the installer and then reinstall macOS High Sierra.

There are various error messages that may be seen in this including: “The path /System/Installation/Packages/OSInstall.mpkg appears to be missing or damaged.  Quit the installer to restart your computer and try again.” or, rarely, more obscure error messages with “macOS could not be installed on your computer” or “An error occurred while verifying firmware. Quit the installer to restart your computer and try again.”

If you get package missing errors or damaged application errors, delete the “Install macOS High Sierra.app” from the /Applications/ folder on the Mac, then re-download the installer from the Mac App Store.

Reboot the Mac, then attempt to re-install Mac OS High Sierra using the “Install macOS High Sierra.app” app again. This should resolve most issues with failed installation attempts.

MacOS High Sierra cannot be installed, or refuses to install on a Mac

If macOS High Sierra will not proceed with installation on the Mac, usually with a notification along the lines of “macOS High Sierra cannot be installed”, it is likely because the Mac is not compatible with High Sierra.

You can check the compatibility list for Macs that support macOS High Sierra here, generally speaking if the Mac runs Sierra and is reasonably modern, it should work.

“Installation of macOS could not continue” error

Some Mac users are encountering an installation error stating “Installation of macOS could not continue. Installation requires downloading important content. That content can’t be downloaded at this time. Try again later.”

Troubleshooting this issue usually involves multiple easy steps: confirming the Mac has active reliable internet access, and then trying to install macOS High Sierra again.

Sometimes a reboot can be sufficient to remedy this error as well.

macOS High Sierra Installation Freezes, Stuck on Black or White Screen

Very rarely, a macOS High Sierra installation fails and remains stuck on a black screen, or all white screen.

If you see an all black or all white screen, the first thing you should do is wait, since the issue may resolve itself, even if it takes a few hours.

Also, with an all black screen, be sure your screen brightness is turned up on the Mac. There are a few reports of the installer screen dimming for whatever reason, and simply turning up the brightness on the display reveals the normal installer screen.

If the installation has completely frozen on a blank screen, you may need to reinstall macOS High Sierra. Try rebooting the Mac and running the High Sierra installer again, or if you have a macOS High Sierra USB boot installer drive, run the installer from there.

If the installation is truly frozen, you may need to reinstall macOS High Sierra via Recovery Mode, by rebooting the Mac and holding down Command+R and then choosing to reinstall macOS.

High Sierra Installation Failed Completely, Mac OS Won’t Boot

This is rare, but there are some reports the installation of High Sierra fails. If the installation fails and the Mac operating system won’t boot at all, usually getting stuck on a blank gray screen, you may need to reinstall system software on the Mac. But first you should try resetting NVRAM / PRAM on the Mac.

  1. Turn off the Mac, then turn it back on again and immediately hold down the OPTION, COMMAND, P, R keys concurrently
  2. Continue holding COMMAND OPTION P R until you hear the boot sound chime again, it usually takes 15 long seconds or so

If the Mac will not boot up after resetting NVRAM, you likely need to reinstall the system software. You may be able to do this with a High Sierra boot drive if you have one available, otherwise you can use recovery mode to reinstall. You can boot into Recovery Mode by rebooting the Mac and holding down Command + R, then choose to reinstall macOS.

If you are unable to reinstall macOS High Sierra, and the Mac will not boot up normally, you can also reboot the Mac and hold down Command+Shift+Option+R and choose to reinstall macOS over internet recovery, which will reinstall the version of Mac OS that shipped on the Mac instead.

APFS Not Working With Fusion Drives or Normal HDDs

APFS support is not currently implemented for Fusion drives or HDD drives in macOS High Sierra versions, but Fusion and HDD support for APFS is expected to arrive in a future software update version.

If you are currently running macOS High Sierra with a Fusion drive of standard spinning HDD, be sure to update system software when new versions arrive to receive support for APFS when it arrives.

MacOS High Sierra Freezing or Stalls

There are mixed reports of Macs freezing, stalling, or otherwise not responding after installing macOS High Sierra.

Some users report that their cursor and keyboard becomes unresponsive with High Sierra, but music or audio will continue to play. This is often triggered after a video starts playing on the Mac, through YouTube, Facebook, or similar services. In such a scenario, the Mac must be forcefully rebooted to regain functionality of the keyboard and mouse or trackpad again. A workaround to that frustrating issue may be to user an alternative web browser, whether it’s Safari, Safari Tech Preview, Chrome, Firefox, or Opera.

There are other reports of Macs completely freezing up with a stuck cursor or a stuck beachball cursor that does not respond or move as well, also requiring a forced reboot of the Mac to regain functionality. These problems could be the result of a bug or compatibility problem with macOS High Sierra, either in core system software or with a third party app or service in use on the Macs. Updating apps and installing available software updates may remedy the problem. If this situation remains unresolved to the user and becomes unworkable, downgrading macOS High Sierra using a prior Time Machine backup is one workaround, though it will move the user back to a prior version of system software to do so.

External Displays Not Working with MacOS High Sierra, or Screens Flickering

There are a few reports of some Macs having issues with external displays after updating to macOS High Sierra. Some users repot screens are flickering or blinking various colors at random, or after a Mac has gone into clamshell mode with an external display connected.

If you are experiencing issues with external displays not functioning properly, try resetting the Mac SMC.

WindowServer causing heavy CPU activity

There are mixed reports of unusually high WindowServer processor activity with some setups in High Sierra. High WindowServer CPU usage can sometimes be resolved by disabling transparency effects in Mac OS.

Be sure to update any updates to macOS High Sierra that are available, as well as any third party graphics drivers if applicable.

Display Artifacts or Screen Graphics Distortions

Some Mac users have reported issues with unusual display artifacts and graphical distortions on their screens. This could be related to issues with the new graphics engine in macOS High Sierra and certain hardware components, or it could be related to third party software or drivers installed on the Mac. Graphics issues that relate to the core system software are likely to be resolved in a future software update, whereas graphics issues dependent on third party software or drivers will likely require an update from those manufacturers and/or developers.

Mac Won’t Wake from Sleep with High Sierra

Numerous users on discussions.apple.com report difficulty with a Mac waking from sleep since installing High Sierra.

The typical troubleshooting steps of resetting SMC or VRAM could be a solution to issues with sleep and wake. Apparently Apple Support has told some users in this scenario to simply reinstall macOS via Recovery mode.

One workaround is to restart or shut down the Mac and then boot up again every time the Mac refuses to wake from sleep, but that’s obviously fairly annoying.

MacOS High Sierra 10.13 Wi-Fi Problems

Some users have reported that macOS High Sierra has difficulty connecting to wi-fi networks. Usually this is a simple matter to resolve, often just toggling the service off, restarting, and turning wireless back on again is enough to fix it:

  1. Turn Wi-Fi OFF from the wireless menu in macOS
  2. Reboot the Mac
  3. Turn wi-fi ON from the wireless menu

If that fails, then try the tips to remedy wi-fi problems with macOS High Sierra that worked with Sierra as discussed here, it’s a series of universal wi-fi troubleshooting steps that can help wireless connectivity problems in nearly all versions of macOS system software.

Additionally, there are mixed reports of difficulties connecting to wi-fi networks that are hiding their router name (SSID). If you connect a Mac to a wi-fi router with hidden SSID then a temporary workaround is to unhide the SSID (router name) and make the SSID visible again. This requires logging into the wi-fi router and that process varies per wireless router vendor.

Some apps are not working in macOS High Sierra

Most apps that worked with Sierra should work with High Sierra, but nonetheless some compatibility issues can persist with High Sierra. Examples of apps reported to have problems with macOS High Sierra include some versions of Final Cut Pro, Motion, Indesign, Logic, Compressor, Microsoft Office, Adobe Photoshop, amongst others. In almost every case, installing the latest version of those apps, along with any other available software updates to macOS, should resolve the problems.

The best approach to this is to update the apps, from the Mac App Store Updates tab, or if the app offers direct software updates, then to install those.

Check with the app developer to see if a new version of the app is available, and to make sure it is compatible with macOS High Sierra.

The Mac feels slow after installing MacOS High Sierra

If you just installed macOS High Sierra on a Mac and it feels slower than usual, it’s likely because of indexing and other maintenance tasks going on in the background pertaining to Spotlight, Siri, Photos app, iCloud, and other system functions.

Simply leaving the Mac turned on and letting it sit idle as it processes necessary background tasks is usually enough to resolve performance problems experienced right after updating macOS system software.

In fact, many Macs may feel faster with macOS High Sierra, particularly with disk related tasks like copying and moving files, due to the new APFS file system. Again, if you have performance issues, simply waiting a while can often resolve the problem.

If performance problems persist, investigating apps or processes using high CPU usage through Activity Monitor is a good starting point. Sometimes an errant process may be running in the background and slowing things down by consuming computing resources.

Additional Troubleshooting Tips for macOS High Sierra

Have you had any issues with macOS High Sierra? If so, were you able to troubleshoot and resolve the problems successfully? Let us know your experiences in the comments below.

Apple releases supplemental update for macOS High Sierra with various bug fixes

Apple has released a supplemental update for macOS High Sierra incorporating various bug fixes for Macs. Apple says it improves ‘installer robustness’, fixes a graphical problem with Adobe InDesign and addresses an issue with mail not sending from Yahoo accounts.

To update, open the Mac App Store and navigate to the Updates tab on a machine running macOS High Sierra.

Try Amazon Prime 30-Day Free Trial

Whilst Apple lists three very specific fixes in the release notes, the security notes indicate that the update also includes two important fixes.

One of these addresses an issue with APFS that has been circulating around the Internet today. The bug meant that some APFS volumes would reveal their password in plain text in the Disk Utility interface.

Rather than being saved into the password field, the password would be set as the ‘hint’ which is readable by anyone. You can see a demo of the problem here:

The supplemental update also includes a fix for a Keychain issue which allowed a malicious application to extract all passwords from the system it was running on.

Apple occasionally pushes out ‘supplemental updates’ for macOS when there are pressing issues that customers are hitting, but there are not enough changes to warrant a new version number (like macOS 10.13.1, which is currently in beta).

If you are installing High Sierra from the Mac App Store for the first time, Apple has updated the download to include the changes contained in the supplemental update.

As always, we’ll let you know about any other changes we see after applying the update, although we naturally do not expect to find anything substantial that isn’t already documented. High Sierra was released on September 25.

macOS High Sierra 10.13 Supplemental Update

Released October 5, 2017

StorageKit

Available for: macOS High Sierra 10.13

Impact: A local attacker may gain access to an encrypted APFS volume

Description: If a hint was set in Disk Utility when creating an APFS encrypted volume, the password was stored as the hint. This was addressed by clearing hint storage if the hint was the password, and by improving the logic for storing hints.

CVE-2017-7149: Matheus Mariano of Leet Tech

Security

Available for: macOS High Sierra 10.13

Impact: A malicious application can extract keychain passwords

Description: A method existed for applications to bypass the keychain access prompt with a synthetic click. This was addressed by requiring the user password when prompting for keychain access.

CVE-2017-7150: Patrick Wardle of Synack

New downloads of macOS High Sierra 10.13 include the security content of the macOS High Sierra 10.13 Supplemental Update.

macOS High Sierra: Enhance Browsing With Safari Website Controls

With macOS High Sierra, Apple upgraded Safari to give us a better experience. We have intelligent tracking prevention and granular controls for websites. These Safari website controls let us create a unique experience on a per-website basis. Preventing auto-play videos, automatic Reader mode, and Content Blockers are a few of these controls.

Finding Safari Website Controls

  1. On your Mac, open Safari.
  2. You can press Command (⌘) + Command (,) on the keyboard, or click Safari > Preferences in the menu bar.
Menu for Safari Website Controls.

Menu for Safari Website Controls

Here you’ll find the new macOS High Sierra controls. The controls are:

  • Reader: Lets you automatically use Reader on websites you choose.
  • Content Blockers: Keep adblockers enabled for certain websites, and you can choose to turn it off for your favorite websites. Or, keep the blockers on for all websites.
  • Auto-Play: Tired of annoying videos that automatically play? Here you can shut them off for good.
  • Page Zoom: Control the page zoom level for individual websites.
  • Camera/Microphone/Location: Here you can choose to prevent websites from accessing these Mac components. Or, you can make websites ask to use your camera, mic, or location.
  • Notifications: Don’t want websites showing notifications in the Notification Center? We already get enough notifications on your iDevices, we don’t need them on the Mac. This section is a bit different. You can check or uncheck a box to let websites ask permission, or not.

Alternatives

You can also access Safari website controls in two other ways:

  1. Right-click the address bar and choose Settings For This Website.
  2. Or, go to the menu bar and click Safari > Settings For This Website.
Accessing Safari Website Controls from the address bar.

Accessing Safari Website Controls from the address bar.

The level of control that Apple provides in Safari makes it more enticing to use over third-party browsers. I’ve always used it as my main browser, but it’s nice to have more control. That’s really what it comes down to: people should be able to control their experience of the web.

How to Downgrade macOS High Sierra

How to Downgrade macOS High Sierra

Some MacOS High Sierra 10.13.x users may wish to downgrade back to macOS Sierra 10.12.x or even Mac OS X El Capitan. Mac users can downgrade from High Sierra to a prior Mac OS release, either by formatting the hard drive and clean installing Sierra or another prior system release, or by relying on a Time Machine backup made prior to the update to macOS High Sierra.

The downgrade method we’ll cover here uses a Time Machine backup to restore to a prior version of macOS and downgrade macOS High Sierra 10.13. If you do not have a Time Machine backup made with a previous version of Mac OS, this will not be possible to follow.

Why downgrade from macOS High Sierra?

For most users, they should not downgrade from macOS High Sierra. Downgrading system software is probably most appropriate as a last resort or a final troubleshooting method, if some particular problem with High Sierra is making the Mac unusable or incompatible with your workflow. There are mixed reports of some Mac users updating to macOS High Sierra and then experiencing a range of problems, from rapid battery life draining, inability for some apps to open, apps crashing, strange performance problems or overall performance degradation, problems with mounting and reading disks, problems with networking connectivity and wi-fi, amongst other issues that could be considered deal breakers.

Important: Keep in mind there is no official downgrade path for macOS. Downgrading macOS High Sierra is accomplished by formatting the target hard drive, thereby erasing everything on it, then restoring from a prior Time Machine backup, or by formatting and then clean installing a prior version of macOS system software onto the computer, and then manually restoring files from some other backup. For our purposes here we will be covering a downgrade by erasing, then restoring from a Time Machine backup made prior to installing High Sierra.

If you do not have a Time Machine backup made prior to installing macOS High Sierra, of the Mac when on Sierra or El Capitan, then you can not proceed with this approach.

How to Downgrade macOS High Sierra to a Prior Mac OS Version

Backup your Mac before beginning this process, it requires erasing the hard drive and removing all data.

  1. Connect the Time Machine backup volume to the Mac if it’s not already attached
  2. Restart the Mac and immediately hold down Command + R keys together to boot into Recovery Mode on the Mac
  3. When the “macOS Utilities” screen appears choose “Disk Utility”
  4. Pull down the “View” menu in Disk Utility and choose “Show All Devices”
  5. Select the hard drive with MacOS High Sierra installed on it, then click the “Erase” button in the tool bar
  6. At the erase drive screen, name the drive and select “Mac OS Extended (Journaled)” as the file system format, click “Erase” when ready – ERASING DESTROYS ALL DATA ON THE SELECTED HARD DISK, DO NOT PROCEED WITHOUT A BACKUP
  7. When the drive finishes formatting, exit Disk Utility to return to “macOS Utilities” screen
  8. At “MacOS Utilities” select the option to “Restore from Time Machine Backup”
  9. Downgrade macOS High Sierra

  10. Select the Time Machine backup drive connected to the Mac as the backup source and choose to continue with the restore process
  11. At the Time Machine “Select a Backup” screen, choose the most recently available backup that has the version of MacOS you want to restore (macOS Sierra is versioned as 10.12.x, Mac OS X El Capitan is 10.11.x) and select Continue
  12. Choose the destination to restore the Time Machine backup to, this will be the hard drive you formatted earlier
  13. Now choose “Restore” to confirm you want to restore the hard drive to the Time Machine backup

The restore of macOS will begin, this can take quite some time depending on the size of the backup, the speed of the hard drive, amongst other factors. Be prepared to wait a while, and let the entire process complete uninterrupted.

When the restore from Time Machine completes, the Mac will boot back up to the state and with the system version where the restored Time Machine backup was made.

Note that if the process of formatting the hard drive mentioned above is usually only necessary for Mac users who changed their file system to thew new AFPS file system available in macOS High Sierra. If the Mac file system was not changed then a regular old restore from Time Machine is possible without bothering with the additional step to format the drive, but nonetheless the data on the driven will be removed and replaced with the data on the Time Machine backup.
