Up until now, your Mac supported all versions of any app on your computer. You can run a 32-bit or 64-bit app smoothly on your computer. However, that changes with the macOS 10.15 release.

After updating your Mac to the latest version of macOS, you will no longer be able to run apps that use 32-bit architecture. macOS is ceasing support for all 32-bit apps and is now moving towards the 64-bit only app environment.

What to do with 32-bit apps?

If you have found that some of your apps still use 32-bit architecture, we recommend that you upgrade them to 64-bit versions as soon as possible. If you don’t, these apps won’t work on macOS 10.15 and later.

Most developers are aware of this change Apple made to macOS and may have already released 64-bit versions of their apps. There are a few ways to check if your existing apps have 64-bit versions available for your Mac.

Update apps from the Mac App Store

If your 32-bit apps were downloaded from the Mac App Store, the developer has likely sent a 64-bit update to the store. If so, all you need to do is update the app as you normally would and it will then be compatible with the latest versions of macOS.

Updates window in the Mac App Store
  • To update your apps, launch the Mac App Store on your Mac.
  • Click on Updates top option to access the update panel.
  • If there is an update available for your apps, you will find a Update button next to them.
  • Click the button and the apps will be updated to the latest versions.

Get the latest version from the official website

It is possible that the 32-bit app you use on your Mac comes from a website on the Internet. If so, you may want to check the app’s official website to see if a 64-bit update is available.

Simply go to the app website and look for a newer version of the app. If it is available, download and install it on your computer. Your existing app will be updated to the latest version.

Update the app from within the app

Many of the apps allow you to get updates from the app menus. This is true for apps like iTunes, Chrome, AppCleaner, among others.

App Cleaner Check the Updates menu

In most apps, you can get new updates by clicking on the app name at the top and selecting Check for updates or a similar option. If you find that an update is available, select it to install it on your computer.


If you haven’t already, go ahead and update all your 32-bit apps to 64-bit versions if you still want these apps to run on the latest versions of macOS. Not doing this will make your apps dysfunctional.
