When Apple launched macOS Mojave in 2018, it announced that it would be the last version of macOS that would support 32-bit applications. From Catalina onwards, you will no longer be able to run 2-bit apps and will have to upgrade to 64-bit versions or find alternatives.
We’re nearing 32-bit-ageddon with the release of macOS 10.15 Catalina sometime in October 2019. The new version of macOS marks the end of old 32-bit apps whose software code was never refreshed to support 64-bit CPUs. The 32-bit app app will appear in its own windows on your Mac desktop, and a second top row menu (the virtual Mac menu) appears below the top menu of your MacOS main installation. As you can see in this window, my Mac is running Catalina, but a 32-bit app The virtual machine's docking station is visible at the foot of the screen, but it's easy. 32-Bit App Warnings When Installing Catalina. When upgrading to macOS Catalina, the installer will show a list of recently used apps that are 32-bit so you know what to expect before installing.
What are 32-bit apps?
Don’t worry, this article will show you how to completely delete these old 32 bit application from macOS Catalina. Delete the application and related files by accessing Finder location a). Move the Application itself to the Trash. Remove Applications Cache. Access /Library/Caches and /Library/Containers and find the application name.
These applications date back to the days when computers ran on 32-bit processors and had 32-bit operating systems. While often described in terms of speed and power, the real difference between 32-bit and 64-bit whether it’s applications operating systems or CPUs, is the amount of memory they can address. 32-bit apps can only address 4GB of RAM, so that is the maximum amount of RAM they can use.
Why has Apple stopped supporting 32-bit apps
Apple has been using 64-bit processors in Macs for well over a decade and macOS has been 64-bit since Snow Leopard, so it was only a matter of time before the Mac became 64-bit only. That time is now. Apple believes that the apps most people use most of the time are 64-bit and those that haven’t made the leap have good 64-bit alternatives.
It has also provided plenty of warning. When you open a 32-bit app in Mojave or High Sierra for the first time, you are warned that it is 32-bit and that you should update it. That warning then appears again every month or so.

Is my app 32-bit or 64-bit?
When you upgrade to Catalina, you’ll be shown a list of any 32-bit apps you have installed and that will no longer work. If you want to check before then, you have two options: one very easy and the other a little more complicated. We’ll start with the manual, more complicated method.
Click on the Apple logo at the top of the screen.
Choose About this Mac.
Select System Report at the bottom of the window.
Click on Applications and scroll to the right until you see the column headed ’64-bit’.
Apps that have a yes in the column are 64-bit and will work, those with a ‘No’ are 32-bit and won’t work.
There is an easier way to check, and it’s the one I recommend because it will allow you to upgrade 32-bit apps to their 64-bit versions at the press of a button. It uses the Updater utility in CleanMyMac X — a cool program by MacPaw — and it’s so simple to use. Here’s how:
Install, and launch CleanMyMac X — it’s free to download
In the app, click on the Uninstaller tab
Now, press the “32-bit” tag in the sidebar on the left
You will see the list of your apps that will not be supported on Catalina. Some of them may already have 64-bit versions available. So instead of updating each app separately and wasting time browsing, just put the cursor on the tab below called “Updater”
Check the box next to each of the apps and press Update. The most recent versions of all the apps displayed will be installed, including 64-bit versions where they’re available.
How can I keep running 32-bit apps on macOS Catalina?
If you have 32-bit apps that you depend on and absolutely can’t use another app, and there is no 64-bit version available, you have three options.
Don’t upgrade to Catalina. If you carry on using Mojave, or whatever version of macOS you’re using, you will be able to keep using 32-bit apps. However, it’s unlikely that the developer of those apps will continue to update them once Catalina is launched, as fewer and fewer people will use them. For example, shortly after Apple announced Catalina, games developer Aspyr announced that it would no longer sell 32-bit games. You will also be missing out on all of the benefits of Catalina.
Upgrade to Catalina on your main Mac but keep another Mac running an older version of macOS. This relies on you having more than one Mac, of course. But it does mean you can enjoy the new features in Catalina and still use your old 32-bit apps. However, the same thing applies as above: your 32-bit apps are unlikely to be supported and updated for long. That includes security and compatibility updates.
Run Mojave in a virtual machine, such as VMWare Fusion.
What else is affected by dropping support for 32-bit?
Some media file formats won’t make the transition to 64-bit. Most of these were created using formats or codecs that rely on QuickTime 7, according to Apple. The QuickTime 7 framework is included in Mojave and its predecessors, but won’t be there in Catalina, so formats created with it won’t work. Apple has a full list of affected formats here.
That means some Final Cut Pro and Motion projects won’t be compatible. However, if you open a project with a 32-bit format, you will see a warning and will be able to convert the library to a 64-bit compatible format at the click of a button. You will also be able to convert Final Cut libraries at any time from the File menu by choosing Check Media for Compatibility. And you can convert files in Compressor.
Dropping support for 32-bit apps in macOS Catalina is part of a long transition from 32-bit to 64-bit that started with hardware and then with the OS in Snow Leopard. Apple has been supporting both for many years but has decided the time is now right to become a 64-bit only operating system. Fortunately, most apps have already migrated to 64-bit and you can update all your apps at once using CleanMyMac X’s Updater. For apps that don’t have a 64-bit version, you need to decide whether to find an alternative or not upgrade to Catalina.

With macOS Catalina and later, there are plenty of great reasons to delete apps. If an app is 32-bit, it has to go. Apple made the decision to discontinue support for 32-bit binaries with macOS Catalina, and many app developers didn’t retrofit their apps to be 64-bit as Apple requested. Old 32-bit apps no longer work on macOS.
Some apps may just be unnecessary. If you have apps for managing photos or your music library, you may find the new Photos app that comes with macOS or the new Music app do a great job, so the old software you’d been using is redundant. It’s gotta go!
Whatever the case, there are quick and easy ways to delete apps from your Mac. We’ll walk you through it!
One thing to know is deleting an app isn’t the same as uninstalling it. There are two ways to delete apps, though: Finder, and Launchpad.
How to delete apps on Mac using Launchpad
In Launchpad, you can pressing and holding the app's icon to bring up the wiggly app management feature. Like iOS, app icons start to shake in-place, which allows you to move them around. Third-party apps also have a small ‘x’ icon on the top right of the icon in this mode, which allows you to delete them.
Another way to delete apps is from Finder. There, you simply select the app, then right-click and select ‘delete.’ In either Finder or Launchpad, you can drag app icons to the trash bin to delete the apps.
(If you’re on an older version of macOS – or OS X, for the much older versions – and managing apps via iTunes, the process is similar. Select the app, right-click, and select ‘Move to Trash.’)

Remove apps with the Finder
Remember when we told you deleting and uninstalling weren’t the same? Deleting is the first step in the process; Apple wants you to do more work!
The completely uninstall an app, follow the instructions for deleting an app above. Then head to your library folder from Finder:
Open Finder
Select ‘Go’ from menu
Hold down ‘option’ key on keyboard; you should see a new option for ‘Library’
While holding down the option key, select ‘Library’
A word of caution before you proceed: DO NOT delete files if you’re not sure what they do. Apple hides the Library for a reason: most people shouldn’t go poking through it and deleting files haphazardly. If you don’t know what a file or folder is for, leave it alone.
Library houses files and folders apps need to operate. Sometimes these files or folders are for updating an app, or managing a Safari extension. Again, Library isn’t a toy. Tread lightly!
When you find a file or folder you know doesn’t belong – and is associated with the app you deleted – you can also delete the file by right-clicking and selecting ‘Move to Trash,’ or dragging it to the trash bin.
Deleting these files completes the deletion of an app. It’s possible those files were doing things necessary for the app that you no longer want, like calling a server or tracking keystrokes. Without the app, those types of features are just spyware.

When you’re done deleting apps and associated files, go ahead and empty your trash bin.
If you’re thinking ‘wow, that all seems sort of scary,’ you’re not wrong. Even seasoned pros get nervous when digging into a computer’s Library file system. There is a better way to uninstall programs from Mac, though!

If the idea of deleting apps and digging into secret libraries on your Mac to remove associated files is daunting, we have a better solution.
CleanMyMacX is a best Mac utility that helps manage your apps and files, in addition to a ton of other features. For now, we’ll focus on app management.
In the CleanMyMacX menu is an ‘Applications’ section on the left pane. It has three options: Uninstaller, Updater, and Extensions. Updater lets you manage updates for apps you want to keep, and saves you the trouble of digging through the App Store just to update an app.

Extensions helps you manage Safari browser extensions, Spotlight plugins, Internet Plugins, and Preference Panes. It’s the simplest and most straightforward way to manage the add-ons some apps demand, which aren’t always caught when deleting or uninstalling an app. When you find an extension you don’t want, just select it and click the ‘Remove’ button at the bottom of the window.
To uninstall apps on Mac, go to the ‘Uninstaller’ option with CleanMyMacX. Here you’ll see apps in a variety of categories. There’s the ‘all’ category for – you guessed it – all of the apps on your Mac. There’s also a section named ‘unused,’ which shows you which apps you’re not really using often.
The ‘Leftovers’ section makes Apple’s ‘Library’ look silly. In CleanMyMacX, Leftovers automatically finds the files associates with apps you no longer have. Hovering over the file in a list brings up the ‘Show’ option, which gives you precise info on exactly what app the file is associated with. No more fumbling through Library and guessing!
There’s also a section for 32-bit apps (remember, we talked about that!) which shows every app that’s no longer supported for macOS. If you really enjoy the app, we suggest reaching out to the developer to see if they will be making it a 64-bit app. If not, go ahead and delete it; it just won’t work on your Mac.
When you’re ready to uninstall programs from your Mac, select the app in any menu you see it in and click ‘Uninstall’ at the bottom of the screen. It’s that easy!
Conclusion
The main goal when uninstalling an app from macOS is to get rid of it completely: files, folders, the app – everything. We’ll also note that if you plan on never using the app or service again, it’s best to request the app developer remove your profile entirely. The method for this varies, but the app or service’s website should have the answer you need.
It takes a long time to delete an app the Apple way, and it’s just not worth it. Digging through the Library is scary stuff, and one wrong move can have a ripple effect on your entire system. No thanks!
We prefer CleanMyMacX, which takes care of the heavy lifting of deleting an app, then removing associated files to completely uninstall it. With a few clicks, you completely rid yourself of an app you don’t want.
