You can downgrade the macOS Mojave beta to macOS High Sierra easily if you need to go back to a stable version on your Mac. If you are tired of testing the macOS 10.14 beta and you want to go back to macOS 10.13.5 to get away from macOS Mojave beta problems, this is that you need to do.
Going back to macOS High Sierra is an easy process, but it is time consuming, so make sure you set aside enough time to complete the process. During parts of this you will not be able to use your computer, so plan ahead.
You will need a Time Machine backup made on macOS High Sierra before you upgraded. This will put everything back where it was before you started using the beta, but you need to have made a backup before moving over to the beta. You can check to see if you have a macOS Mojave Time Machine backup, but unless you’ve been doing important work on the beta, it’s not a major issue.
This guide will show you how to complete a macOS Mojave beta downgrade to go back to macOS High Sierra.
How to Downgrade macOS Mojave Beta to High Sierra
Downgrade from the macOS Mojave beta to macOS High Sierra.
Connect your Mac to power and plan on spending a little time with your Mac to get this process started. The first step is to erase your Mac. Then you will install macOS High Sierra from a clean install. Finally you will restore a Time Machine Backup, which will get you back to where you were right before you switched to macOS Mojave.
You’ll need a good internet connection and this guide assumes you installed the macOS Mojave beta on your main drive.
Erase Your Mac Drive
- Restart your Mac using the Apple menu in the upper right.
- When it is restarting hold Command and R until the Utilities menu appears.
- Choose Disk Utility
- Click Continue and then Click on Startup Disk. Often labeled Macintosh HD
- Click Erase.
- Choose the APFS file format from the list and click on Erase.
If you don’t have a solid state drive you may need to choose Mac OS Extended for the format in step 6, but most Apple computers will be using APFS. He3re’s more from Apple on which you should choose.
Reinstall macOS High Sierra
It will take a few minutes to erase the drive. Once completed, you can start installing macOS High Sierra.
- On the main macOS Utilities screen, choose Reinstall macOS.
- Click Continue and then Agree to any terms and conditions.
Wait for the Mac to restart and then you are back on macOS High Sierra.
Restore Your Time Machine Backup from High Sierra
Restore a Time Machine backup that you made on macOS High Sierra.
Now that you are back on macOS High Sierra, you still need to install all of your files, apps and data. Your Time Machine backup includes all of this information and can put it back in place quickly. If you prefer, you can skip this step and start fresh, which may be smart if you were having macOS High Sierra problems.
- Restart your Mac and hold Command and R to get to macOS Utilities.
- Choose the Restore From Time Machine Backup option.
- Click Continue. Then choose the backup that you want to restore from. You will need to connect to WiFi if you have a wireless Time Machine drive or plug in if it is on an external drive.
- Click Continue after you choose the latest backup and then wait for the restore to complete.
The Time Machine restore process will take a while to complete. The best thing you can do is step away and check in on your Mac every 30 to 60 minutes to see if it is done.
11 New macOS Mojave Features That Will Change How You Use Your Mac
macOS Mojave Dark Mode
Apple finally offers a dark mode for the Mac that is built-in and that carries over to your apps. The new Dark Mode includes a darker desktop background and darker colors in all of the menus and settings.
This puts the focus on your content and isn’t as blindingly bright when you are using your Mac at night. With Dark Mode enabled the built-in Mac apps like Mail, Messages, Maps, Calendar and Photos also appear on screen with a darker look.
Apple allows third party apps to support Dark Mode. By the time the public Mojave release date arrives expect many of your favorite apps to support this feature.
Stacks on the Desktop
The desktop can quickly clutter up if you use iCloud or even if you just love to store items you are working on there.
With macOS Mojave, your desktop now has the ability to Stack related documents together so that your desktop is cleaner and items are easier to find.
You can group by file type, a variety of date information or by tags. You can scroll through the various stacks and find what you are looking for easily.
This is a feature you can choose to use, or choose to ignore if you don’t like it.
Apple made the desktop dynamic in macOS Mojave. It looks like a very slowly moving version of the Apple TV screensavers and it’s a small but cool feature.
Throughout the day, your desktop will change to show the sun or moon going over the Mojave dunes. This only works with the default backgrounds that Apple includes in macOS 10.14.
We hope that Apple will add more options or developers will be able to add support like this for other backgrounds that tap into the macOS 10.14 settings.
macOS Mojave Finder Upgrades
The macOS Mojave Finder is all new with an array of features and options that will make it easier to manage your files without opening other apps.
Starting with the new Gallery View, you can easily see pictures or videos in Finder and browse through them. This lets you visually sort through all of your files and you can use the new Preview Pane to see more metadata about the media you are looking at.
Quick Actions let you quickly change files. One example is making a PDF password protected right from inside Finder. You can also run Automator Actions on files.
The upgraded Quick Look feature allows you ro see a full preview of a file and then edit it immediately. You can rotate or crop images, trim audio and video files and more.
Read Apple News
Apple News is coming to the Mac on macOS Mojave. Once you upgrade you’ll get all of your favorite Apple News sources right inside an app on your Mac.
This brings the same curated news home page and your personalized stories to the Mac that you’re reading on your iPhone or iPad. You will get the full Apple News experience including Siri Suggested topics, Channels and sources.
If you love using Apple News to stay on top of the news that matters to you, this is a very nice upgrade that is free with macOS Mojave.
Home App on macOS Mojave
Do you control your Smart Home with Siri and the Home App on your iPhone or iPad? If so you’ll love this new macOS Mojave feature that adds the Home app to your Mac.
As someone who works at home, I’m excited to control my home using the Mac, which I am likely already using, instead of reaching for my iPhone. This also looks like it will make setting up rooms and automations easier than on an iPhone.
Your existing Home syncs through iCloud to the Mac so you don’t need to reconfigure anything. This also shows you notifications for doors and other HomeKit items that you want to know about.
Apple finally supports Group FaceTime calls. Until now you’d need a third party app to talk to two people at once on a Mac or iPhone, but with iOS 12 and macOS Mojave you get support for up to 32 people.
The feature shows an array of users across your screen, focusing on who is talking, or allowing you to pick one participant to look at in full. Other users will need to be on iOS 12 or macOS Mojave for this to work.
On iPhone and iPad users can also bring Animoji and Memoji to the party instead of showing your face. This will also integrate with iMessage so you can quickly start a Group FaceTime call with people in a group message.
Members can join with video, or join with just audio. The Apple Watch even supports joining with audio only.
New Mac App Store
The Mac App Store in macOS Mojave will look and feel more like the iOS App Store does in iOS 11.
You will now see app roundups, app features and other content that highlights Mac Apps. Apple hopes this will help you find apps to use on your Mac.
There is now a tab for new and updated apps called Discover, which will help you find a great new app to try. Other categories include; Create, Work, Play and Develop so you can sort through apps based on what you are trying to do.
Apple is also working with developers to bring apps from Microsoft and Adobe to the Mac App Store.
macOS Mojave Privacy & Security Features
With the new macOS Mojave Safari upgrade you will see privacy and security upgrades aimed at keeping your information private and safe.
One of these features is an upgraded Intelligent Tracking Prevention mode that stops websites from showing Like and Share buttons for social media or comments. These can be used to track users across the web. Safari also changes options to precent tracking based on system information.
Safari already helps you come up with new passwords, but the browser will now help you create stronger passwords and let you know if you are re-using a password that makes it less secure.
Apps now need to get permission to use the camera, microphone or tap into personal data from Mail or Messages.
New macOS Mojave Screenshots Tool
If you routinely take screenshots or screen captures on your Mac, you will love the new macOS Mojave screenshot tool.
With this tool you can get more control over the screenshots you take. You can also record your desktop using the Screenshot tool so that you can capture an important part of a webpage, or a specific task you are trying to share.
Once you take a screenshot in macOS Mojave, you can click on it in the bottom corner and open it up in Preview to quickly edit and then share without cluttering up your desktop.
Use Your iPhone to Scan or Take Photos to Your Mac
Apple adds a cool new feature called Continuity Camera to macOS Mojave.
This allows you to quickly tap into your iPhone to take a picture or to scan a document. Simply choose to use your iPhone to add a picture or scan something and it will power on to the camera. You can take a photo and then accept or re-take. Once you finish the photo appears instantly on your Mac and you can use it.
There’s no need to try to use the mediocre webcam to take a photo of something, just tap into the excellent cameras on your iPhone. This is also perfect if you need a scanner and you don’t want to buy a dedicated device.
