Apple has already informed developers of which Mac hardware will be supported under macOS Mojave. The general rule of thumb is that if your hardware is from 2012 and newer (other than regular MacBook that must be from 2015 and newer), you'll likely be able to enjoy all of the macOS Mojave features including the long awaited Dark Mode. These are the devices that can run iOS 12 and macOS Mojave. There’s good news and bad news for fans of keeping old hardware running. While iOS 12 will run fine on any device that currently runs.
When Apple announced in 2017 that macOS High Sierra would be the last version of the Mac operating system to support 32-bit applications without limitations, that seemed to spell the beginning of the end for those apps on the Mac. And when it launched macOS Mojave beta in June 2018, it reinforced that message, saying that Mojave would be the last version to support 32-bit apps in any way. Most 32-bit apps still work, however, while others have been or will soon be updated. A third group have other problems with Mojave that mean they won’t run properly and have not been updated, their developers preferring to allow them to reach a natural end of life on the Mac.
Will macOS Mojave support 32 bit apps?
If you still run 32-bit apps and are running High Sierra or Mojave, you will probably have seen warnings telling you that the app is not optimized for the version of the OS you’re running. Most 32-bit apps still run fine, others will struggle. So, the answer to the question ‘will macOS Mojave run 32 bit apps’ is that it very much depends on the app. Technically, 32 bit apps in Mojave will run but with some limitations on what they are able to do.
How do I know which apps are 32-bit?
There’s a very simple way to find out which of the apps installed on your Mac are 32-bit.
1. Click on the Apple menu and choose About this Mac
2. Press System Report…
3. Scroll down to the software section and click on Applications
4. Enlarge the window so you can see all the columns
5. Grab the bar that divides the list of apps and the description text and drag it down so you can see more of the list
6. Go through the list and look at the ’64-bit’ column
7. If you see any ‘No’s in the column, those apps are 32-bit
What do I do if I find 32-bit apps in Mojave?
You could do nothing, after all 32-bit apps will still run in Mojave. Or you could launch each one to see how it runs. But you will need to take action soon, especially if you rely on those apps, because they won’t run in future versions of macOS.
The best course of action is to check if there are updates available for any app you find that is 32-bit. There are two ways to do this, the fast way and the slow way.

4. Install any updates it finds
5. Repeat for the next 32-bit app
What if there’s no update?
If there’s no 64-bit version of an app you use regularly, check the developer’s website to find out if they plan to release one before September 2019. https://treegear691.weebly.com/best-photo-and-movie-app-for-mac.html. If not, it’s time to find a replacement for the app. In many cases, the developer will have released a completely new version of the app, or a replacement for it, and you’ll have to purchase that separately. In other cases, you’ll need to find a completely new app to use.
Once you’ve replace the app, it’s a good idea to uninstall the 32-bit version from your Mac, to free up space and reduce the chance of conflicts. You can do this manually, by going through folders in your Mac’s Library and tracking down every file associated with the app. Or you can use the Uninstaller module in CleanMyMac which will remove every trace of an app with on click.
Which well known apps are affected?
Quite a number of apps from big developers like Apple, Microsoft, and Adobe will stop working when macOS stops running 32-bit apps altogether. Here are a few of them:
Apple
- Aperture
The last version of Aperture, which was replaced with Photos, was released in 2014 and is 64-bit so may run without a problem. However, older versions are 32-bit and won’t run at all once macOS stops supporting those apps completely.
- iWork
The first 32-bit version of iWork was iWork 13, so if you’re running an older version, it won’t work after September 2019. The good news is that the current iWork apps are free to download from the App Store.
- Final Cut Pro and Logic Studio
Apple’s professional video and audio tools were superseded by Final Cut Pro X and Logic Pro X in 2011. If you’re still running the older versions, now is the time to move on. There is one thing to note, however. Many of the apps that used to come bundled with both Final Cut and Logic Studio were never updated. These include DVD Studio Pro, Soundtrack Pro, Cinema Tools, and Color. So, if you’re still running older versions of those apps, you’ll need to find replacements.
Microsoft
Office 2011 is a 32-bit application and won’t run once macOS stops supporting 32-bit apps altogether. Office 2016 was updated to 64-bit in 2016. If you have an Office 365 subscription, you can update Office 2016 through that, if necessary. If you bought the standalone version of 2016 and are still running the 32-bit version, you can download an update from Microsoft’s website or by using CleanMyMac’s Updater module.
- Adobe
All Creative Cloud versions of Adobe apps are 64-bit and so if you have a Creative Cloud subscription you won’t have any problems with Mojave or future versions of macOS. If you’re still running CS 5 or CS 6 versions of Adobe applications, compatibility varies on an application by application basis.
Photoshop CS 5 is 64-bit but there have been many reported compatibility problems with Mojave. CS6 seems to work fine with the latest version of macOS. Illustrator CS5 is 32-bit so, at the very least, you should update it to CS 6 if you can. InDesign wasn’t updated to 64-bit until Creative Cloud, so if you’re running CS 5 or CS 6 you should update to Creative Cloud before September 2019. Premiere Pro has been 64-bit since CS4 and After Effects since CS5, so as long as you are using those versions or later, you should be ok. Lightroom has been 64-bit since Lightroom 2.
Other notable apps
- Ableton Live 10
According to the company, Live 10 is not yet fully Mojave compatible. It says on on its website: ‘ We advise users to wait until a fully compatible version of Live is released before updating to macOS Mojave.’
- Avid Media Composer
Avid says that Media Composer is not ‘“supported” on Mojave currently. That doesn’t mean that it won’t work, but it does mean the company is aware of several issues.
- Avid Pro Tools
The hugely popular audio production tool is another one of Avid’s products that company says is not currently supported on macOS Mojave.
- Avid Sibelius
Like Pro Tools and Media Composer, Avid says it is aware of issues with its Sibelius musical score editor and Mojave and advises against running it on Apple’s latest operating system.
- Ecamm Call Recorder for FaceTime
This popular app, that allows you to record FaceTime calls for, say, interviews or podcasts doesn’t work with Mojave. Ecamm says that Apple has tightened up security and made changes to FaceTime that mean Call Recorder will no longer work.
- Endnote
The company says of versions X7, X8, and X9: “Through our testing and reports from users, we discovered some issues with the EndNote PDF viewer that existed with macOS High Sierra have persisted with macOS Mojave.” It adds that Endnote X6 is not “officially compatible” with Mojave at all.
- Extensis Suitcase Fusion 8
Suitcase Fusion 8 is currently a 32-bit application and the company says: “ Extensis is working to make its applications 64-bit compatible for all future macOS updates and will provide public updates as soon as they are available.” It also said in a support post that if users dismiss the “not optimized” warning, it should work as normal. Obviously, that won’t be the case in future versions of macOS, which will only run 64-bit applications.
- Propellerhead Reason 9.5.4 and earlier
The company advises users running earlier versions of its audio creation tool to update to version 10.2.
While macOS Mojave will run 32-bit applications, it does so with limitations. Those limitations depend on the application you’re trying to run. Most developers have already released 64-bit versions of their apps and it’s a good idea to upgrade to them now. When you do, you can use CleanMyMac to quickly identify which apps on your Macs have updates available and to uninstall the 32-bit versions you no longer need.

If you’re excited at the launch of macOS Catalina and want to try out all the new features for yourself, you can download the public beta from July and give it a go. However, as it’s beta software, it comes with a health warning and you should take precautions when testing it. One way you can do that is to create a dual boot system so you can still boot into Mojave, or whatever macOS you’re currently running, when you need to. Here’s how to dual boot macOS Mojave and macOS Catalina.
Clean up your drive beforehand
Once installed, macOS Catalina will have access to all your files and folders, so back up your Mac just in case it damages them. You can use Time Machine or any other backup tool. Just make sure you have a backup of your entire Mac before you download macOS Catalina. You should also consider turning on FileVault. It will slow your Mac down, but will force Catalina to ask for permission before it access encrypted files and folders.
The other thing you should do is clear out the junk on your Mac. We’re going to install Catalina on your main startup disk (yes, you don’t need an external disk!), so the more space you have available, the better. It’s not often that I recommend specific applications, but for this purpose, I’m a big fan of CleanMyMac X. It makes it really easy to identify what’s taking up all your disk space, thanks to its System Junk tool. And it makes it easy to remove junk files, too. You can either let it scan your whole Mac, or focus on specifics like iTunes, Photos cache files, Launch agents, or large and old files you no longer need to access regularly. You can download it here, so I recommend giving it a try, you might find that it frees up tens of gigabytes of space.
What you’ll need for macOS Catalina
- Access to macOS Catalina. It’s only available to Apple developers until July. Then there will be a public beta available. In October, the full version will be available on the Mac App Store.
- A Mac that’s capable of running Catalina. Here’s the list of compatible Macs:
MacBook 2015 and later
MacBook Air 2012 and later
MacBook Pro 2012 and later
IMac 2012 and later
IMac Pro 2017 and later
Mac Pro 2013 and later

3. An APFS-formatted startup disk. If your Mac is running High Sierra or Mojave, its startup disk is probably formatted as APFS. The exception is hard disks or Fusion drives running High Sierra. You can check the format of your startup drive by clicking Launchpad > Disk Utility.
If your start-up disk is not formatted as APFS, your best option is to install Catalina on external drive. In this case, instead of using Disk Utility to create another volume on your startup disk as shown below, you should grab a USB stick or external hard drive with at least 16GB capacity and use Disk Utility to erase it and reformat it. Then, when you install Catalina, below, choose it, rather than the second volume, as the location for the install.
Download and install macOS Catalina
Depending on when you read this, macOS Catalina will either be in developer beta, public beta, or full release. If it’s still in developer beta, you’ll need to wait until the full public beta is available in July, unless you’re a registered Apple developer.
Before you download macOS Catalina, you’ll need to create a volume on which it can be installed. If you’re running Mojave, your startup disk will be formatted as APFS. This makes it easy, because APFS doesn’t require you to create a new partition. It uses containers, each of which can host multiple volumes. Here’s how to create one for Catalina.
- Go to Applications>Utilities and double-click Disk Utility to launch it.
- Select your startup volume in the left sidebar.
- Click on the Edit menu and choose Add APFS Volume.
- When “Add APFS Volume to container” appears, give your new volume a name, say “Catalina”, and choose APFS as the format.
- You can ignore the section for reserving space for the new volume, it will be given what it needs as it shares space with your startup volume.
You’re now ready to download and install Catalina.
- Click here to begin downloading the public beta.
- When the download starts it will prompt you to choose a location for the installation. Choose the volume you just created.
- Click process to install macOS Catalina
Your Mac will restart several times during the installation process. Once it’s finished, you will be able to dual boot into wither macOS Catalina or macOS Mojave.
How to dual boot macOS Mojave and macOS Catalina beta
Once you’ve installed macOS Catalina, you have two options for choosing which OS to boot into.
- Hold down the Option key when you restart or boot your Mac, then choose macOS Catalina or Mojave.
- Before you shutdown or restart, go to the Apple menu and choose System Preferences. Then choose Startup Disk and select the one you want to boot into next time.
My apps don’t work on macOS Catalina
First thing people notice after they run a new OS is some of their apps stopped working. Annoying as it is, not all developers have yet optimized their software for Catalina. A large portion of your applications may still be 32-bit, which macOS Catalina won’t support.

There’s a quick 5 second way to check which of your apps are 32-bit.
I do it using the Uninstaller tool in CleanMyMac X. You can download its free version here.
- Launch the program and click the Uninstaller tab
- Now, select 32-bit in the sidebar
From there you can find your long-forgotten apps, delete them. And, most importantly, update them to the latest versions using the Updater tool (the one below Uninstaller).
Dual-booting macOS Catalina and MacOS Mojave is a great way to try out Apple’s new operating system without having to use it every day. You should never use a beta version of an OS for day to day work, so it avoids that problem too. If your startup disk is formatted as APFS, you can even have both operating systems installed on the same disk. Just remember to backup your Mac before you start, and to use CleanMyMac X to clear out junk files.
