If you’ve installed macOS Catalina and run into problems with some of your apps, or you’ve just decided that you don’t like it as much as Mojave, the good news is that you can downgrade back to the previous version of macOS. The bad news is that it’s a lengthy process with several steps. Read on to find out how to do it.

- I wouldn't advise using Lion (10.7) as your everyday OS if your Mac is capable of running something more recent. Even if you don't care about the general improvements in capability and (in my opinion) usability with the latest OS, Lion is no longer supported by security updates and you will find many more recent apps won't work on it (and some websites may also fail to work well on Lion's.
- It searches for apps everywhere on your mac, even on other hard drives. So unless you're using a backup system such as Time Machine, you will want to make a zip or something of the old version of the app, to make sure the App Store doesn't upgrade the backup copy you've made instead of upgrading the one in the Applications folder – Abhi.
- Transport Layer Security (TLS), and its now-deprecated predecessor, Secure Sockets Layer (SSL), are cryptographic protocols designed to provide communications security over a computer network. Several versions of the protocols find widespread use in applications such as web browsing, email, instant messaging, and voice over IP (VoIP).Websites can use TLS to secure all communications between.
1. Back up your Mac
https://pfmgxna.weebly.com/blog/no-x-to-uninstall-app-on-mac. Cocoapods 1.0.0 Update: note that if you have 1.0.0 installed, attempting to reinstall an older version on top will leave 1.0.0 as the default version, so you have to sudo gem uninstall cocoapods first, then select 1.0.0 as the version to remove.
You should have backed up your Mac before you upgraded to Catalina, as you should before you perform any major upgrade or make any significant change to your Mac. However, the files you’ve been working on since you upgraded won’t be up to date on that backup. So, you should copy those files to an external disk, or a cloud storage service like Dropbox or iCloud Drive so you can retrieve them easily when you downgrade. We’re going to completely erase your Mac’s startup disk, so it’s important to copy anything you need now.
Before you backup, however, you should take steps to remove the junk and clutter from your Mac. There’s no point in backing up all the clutter along with the files you really need. To do that, I recommend CleanMyMac X. It’s the easiest way to clear out the clutter on your Mac. Here are just a few things it can do:
- Delete years worth of system junk
- Find hidden apps and folders
- Neutralize Mac-specific malware, like key loggers
- Manage hung apps and heavy CPU consumers
- Update all your software to the latest-supported versions
As you can see, CleanMyMac X does a lot more than just clear out junk files before you backup your Mac. It’s well-worth keeping it on your Mac and using regularly to keep your Mac running smoothly.
2. Save your passwords
When you downgrade mac OS Catalina, you’ll delete everything from your hard drive, including licence keys and settings. So, in addition to making sure you copy all the files that have changed since you last backed up, you should make a note of those. If you use a password manager that syncs with other devices and allows you to store licence codes and encrypted notes, you could use that. If not, any app that allows you to sync encrypted notes will do. Or you can use Apple’s Notes app. It’s also a good idea to take screen grabs of settings to make it easier to restore them later. Remember to copy the grabs to a cloud storage service or an external disk.
3. Create a bootable installer of macOS Mojave
Note, you can skip this step if your Mac shipped with macOS Mojave or if you made a backup with Time Machine before you upgraded to Catalina.
- If you’re reading this before macOS Catalina ships, you can go to the App Store and search for Mojave, then download it. If it tries to install when it’s finished downloading, quite the installer.
- If you’re reading this after Catalina ships, you can download Mojave here, but only on a Mac that’s not already running Mojave. When you click that link, Software Update will launch and start to download Mojave. When it’s finished, quit Software Update.
- Grab a USB stick with 16GB capacity or an external hard drive or SSD and plug it in to your Mac.
- Launch Disk Utilities and Erase the Drive or USB stick, formatting it as Mac OS Extended (Journaled) and selecting GUID partition map if a selection is available.
- The easiest way to create a bootable installer is to use DiskMaker X. However, you can also do it in Terminal like this:
- Launch Terminal from Applications - Utilities
- Type:
sudo /Applications/Install macOS Mojave.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled
where ‘Untitled’ is the name of your USB stick or external hard drive - Press Return and wait for the word Done to appear in Terminal.
Whichever method you used, you should now have a bootable macOS Mojave installer. Keep it safe.
4. Uninstall macOS Catalina
- Make sure your Mac is connected to the internet.
- Click on the Apple menu and choose Restart.
- Hold down Command+R to boot into Recovery mode.
- Choose Disk Utility in the macOS Utilities window
- Select your startup disk
- Choose Erase
- Quit Disk Utility
How to downgrade Catalina to Mojave if your Mac shipped with Mojave
- Once you’ve erased your startup disk and quit Disk Utility as described above, choose Reinstall macOS from macOS Utilities.
- Press Continue.
How to rollback from Catalina using a Time Machine backup
If you backed up your Mac with Time Machine before you installed Catalina, you don’t need to create a bootable installer – you can just reinstall Mojave from your Time Machine backup. Make sure it’s plugged in if it’s an external disk. If it’s a network disk, make sure you’re connected to the network.
- Once you’ve erased your start up disk as described above, choose Restore from Time Machine backup in the macOS Utilities window.
- If your backup is on an external disk, select it. If it’s on a network disk, select it and choose Connect to Remote Disk.
- Type in your username and password for the remote disk if necessary.
- Select the data and time of the backup you want to restore from.
- Follow the onscreen instructions.
5. Install Mojave using a bootable installer
If you have a Mac that didn’t ship with Mojave and you don’t use Time Machine to backup, you’ll need to reinstall Mojave from the bootable installer we created earlier.
- Plug in the installer disk.
- Go to the Apple menu and choose restart, then hold down the Option key.
- Mojave will start installing on your Mac.
- When it’s finished, your Mac will restart and the Setup Assistant will appear
- Follow the steps in the SetUp Assistant to set up Mojave
Restore your settings
If you have reinstalled Mojave from a bootable disk, rather than a Time Machine backup, you will need to reinstall applications and copy documents across from your backup. That’s where those notes and screen shots you made earlier come in handy!
Once you’ve restored your settings and reinstalled all the apps you need, your Mac is ready to use again, running Mojave instead of Catalina.
Tip: If you want to roll back to an earlier version of macOS than Mojave, you can. To reinstall the OS your Mac shipped with, use the method in ‘How to downgrade if your Mac shipped with Mojave’. If you want to roll back to a version of macOS newer than the one your Mac shipped with but older than Mojave, you can download Sierra and earlier versions from the Mac App Store. Then follow from Step 3 in ‘Create a bootable installer of Mojave’.
My Mac is still underperforming, what to do?
You thought that reverting to macOS Mojave would get your Mac back to norm. But if it didn’t and you still experiencing sudden freeze-ups and glitches, full disk cleanup is your answer. Probably there are too many conflicting system junk files on your drive that you need to plow through.
https://pfmgxna.weebly.com/veryfitpro-app-for-mac.html. You don’t need a regular disk cleanup app — most of them are scam — but this tool, CleanMyMac X, is notarized by Apple, and can really do helpful optimizations on your Mac.
- Download the free edition here
- Go to Maintenance tab
Now you can perform some of the tasks suggested by the app, like running Maintenance Scripts. Also, check the System Junk tab and remove all the useless files it recommends you to delete.
As you can see, it is possible to uninstall Catalina if you decide you don’t want to continue using it. It’s essential, however, that you backup your Mac before you upgrade. And remember, before you backup, clear out the clutter with CleanMyMac X. That way you won’t use precious space on your backup drive copying over junk files.

With its enhancements and limitations, the new macOS 10.15 is inescapable. The official release is planned for September 2019, but Apple savvy users have tested Catalina long before — with the macOS 10.15 beta. If you’re not one of them, you might want to check the best assets of the new macOS here.
Catalina comes with extended workspace, no iTunes, and 64-bit app architecture. According to early user reports, the beta feels faster and more stable than the previous ones.
It’s not all rosy, though. By switching to 64-bit apps, macOS Catalina stops supporting the apps with 32-bit architecture. For you, this means no access to over 200 popular applications.
The bundle of incompatible apps have been discovered by iOS developer, Steve Moser, when he was testing the developer beta of Catalina. Once you upgrade, you can find the full list in Library/Apple/Library/Bundles.
We’ve collected the major Adobe, Apple, and Microsoft programs you’ll have issues with in macOS Catalina. No need to panic just yet — there are ways to fix this.

Which Mac apps will stop working
The problem of Catalina incompatibility is not only about third-party apps. Apple is not 100% prepared too. For people working with multimedia projects, it’s important to know which Adobe software won’t be working after the update. So take a deep breath, and see what’s going away.

Apple apps not working in Catalina
- iWork’09, an old version of Apple’s office suite that includes Pages, Keynote, and Numbers. Apple released the newer bundle with 64-bit apps in 2013 — so an update will fix the problem here. Alternatively, you can get more advanced substitutes like Ulysses for writing and markdown.
- Final Cut Studio and Logic Studio. You can upgrade to Final Cut Pro X and Logic Pro X instead.
- Apple’s DVD Player (older versions released before macOS Mojave).
- Aperture. The app won’t work in Catalina, even though it’s 64-bit. Apple recommends to switch to Photos or Adobe Lightroom. If you need a pro-level editor for a moderate price, you might want to try CameraBag Pro.
Microsoft apps not working in Catalina
- The 2011 version of Microsoft Office (Word 2011, Excel 2011, PowerPoint 2011, Outlook 2011). To continue using the apps, get the 2016 version of Microsoft Office. Or, you can switch to Apple’s iWork, Ulysses, or other Mac alternatives.
Adobe apps not working in Catalina
Since Adobe moved to a subscription model called Creative Cloud, there has been lots of shared components introduced across Adobe products. For instance, if you buy a subscription, you may get a 64-bit application with a 32-bit installer. This won’t work in Catalina. Adobe says they are working on updating shared components for macOS 10.15. In the meantime, be aware of the incompatible apps:
- Photoshop. There have been issues with the 2018 version of Photoshop in macOS Mojave, so you may expect the trouble in Catalina as well. If you want to use the app, Adobe recommends to get Photoshop CC 2019.
- Premiere Pro. The app is 64-bit, but there have been reported issues related to camera and microphone access in macOS 10.15.
- Illustrator. The CS5 version won’t be supported in Catalina, but you may switch to CS6.
- InDesign. To this one, you have to say goodbye. At least, for now. The latest CS6 version hasn’t been updated to 64-bit architecture yet.
- Acrobat Pro. The recent version of the app, as well as Acrobat DC and Acrobat Reader DC, have 32-bit components. So it’s a no, for now.

Most Adobe apps — even those with 64-bit architecture — are known for Dark Mode issues. So if you continue using the apps in Catalina, be careful with the darkness.
As a safe alternative, get CameraBag Pro or Capto. They work equally well for professional designers and amateurs. Both are available on Setapp, a subscription package that, by the way, offers many more photo editing tools — just ask for it.
How to check if an app is compatible with Catalina
We’ve talked a lot about outdated app architecture, so the first thing you’ll want to check when upgrading is whether your app is 32-bit. Tutuapp. Here’s an easy way to do it on Mac:
- Click on the Apple logo in the upper left corner.
- Select About This Mac > System Report.
- Navigate to Applications under the Software tab.
- Find your app on the list and check whether it says “Yes” in the 64-bit column. In macOS Catalina, there will be no such column. So, you’ll have to click on the app and see a short description that says “Kind: 64-bit.”
We also recommend to pay attention to the “Obtained from” field. Ideally, it should say Apple, Mac App Store, or Identified Developer. Avoid using apps that are specified as “Obtained from Unknown,” while these are most likely to misbehave.
If you want to uninstall 32-bit applications before upgrading, CleanMyMac X will swipe everything away for you. Open the app and go to Uninstaller. Filter your apps by 32-bit and click Uninstall. Instead of checking System Report every time, you can find and remove every outdated application in a few seconds.
If your app doesn’t work in macOS 10.15
The problem with 64-bit architecture is that many developers choose not to optimize their 32-bit applications for Mac with the release of Catalina. If that’s the case and you can’t find an alternative for the missing app, you might need to downgrade back to Mojave. Luckily, there’s a way to fix most problems with apps not working in Catalina:
- Check whether a developer has a 64-bit update for your app.
- Look for an alternative app compatible with macOS 10.15. For instance, most of the Adobe apps for photo and video editing can be replaced with Capto or CameraBag Pro.
- Roll back to Mojave and continue using 32-bit apps. You should note, though, that Apple may stop the support for Mojave by 2020, which means it will stop supporting 32-bit architecture sooner or later.
While many developers continue working on Catalina compatibility, there will be further changes to the list. For questions and quick insights, follow the MacRumors discussion on Catalina apps.
