How to find and upgrade 32-bit apps on your Mac

So far, your Mac has supported all versions of any of your apps. You can run an application whether it is 32 bit or 64 bit without any problem on your machine. However, that will change with macOS version 10.15.

After you update your Mac to this latest version of macOS, you will no longer be able to run any apps that use the 32-bit architecture. macOS is dropping support for all 32-bit apps and is now transitioning to a 64-bit-only application environment.

That means for end users like you and me we need to upgrade our apps to 64 bit version, otherwise we will lose access to apps in latest macOS update . Of course, we understand that not many of you are tech-savvy and you may not know whether an application is 32-bit or 64-bit.

Therefore, we’ve put together this guide that shows you how to find 32-bit apps on your Mac and gives you advice on what you can do with them. At the end of the tutorial, you’ll see how you can run your apps even in the latest macOS update on your Mac.

Use the System Report to find a list of 32-bit apps on your Mac

System Report is a great utility on your Mac that allows you to find out a lot of information about the hardware and software elements of your machine. While its main purpose isn’t to help you find apps on your Mac, it does help you find all the 32-bit apps on your machine.

Here’s how to access a list of all 32-bit apps installed on your Mac:

  • Click the Apple icon in the upper left corner of the screen and select About this Mac. On the following screen, click the button that says System report below your Mac details.

Use Activity Monitor to find 32-bit apps on Mac

Another way to find 32-bit apps on your Mac is to use the Activity Monitor tool. This tool allows you to find out if an application is 32-bit, but the application must be running while you try to find this information. You won’t find any information if the app isn’t running on your Mac.

  • Launch the app in question on your Mac but do nothing with it. Open Activity Monitor from Launchpad.
Search bar with Activity Tracker entered
  • Right click on any column name (CPU Time, Thread, etc) and select Kind. It will add a new column to the right of the existing columns.
Right-click the menu in the Activity Monitor window
  • Newly added Kind column will tell you whether the application currently running on your Mac is 32-bit or 64-bit.
Type column in Activity Monitor window

Both methods described above will make it easy for you to find all the 32-bit apps available on your Mac.

What to do with 32-bit apps?

If you find that some of your applications still use 32-bit architecture, you may want to upgrade them to 64-bit versions as soon as possible. If you don’t do that, these apps won’t run on macOS 10.15 or later.

Most developers are aware of this change that Apple has made to macOS, and they may have released 64-bit versions of their apps. There are several ways to check if your existing applications have 64-bit versions for your Mac.

Update apps from the Mac App Store

If your 32-bit apps were downloaded from the Mac App Store, it’s likely that the developer pushed a 64-bit upgrade to the store. In that case, all you need to do is update the app as usual and then it will be compatible with newer versions of macOS.

Updates window in the Mac App Store
  • To upgrade your app, launch Mac App Store on your Mac.
  • Click Update at the top to access the update panel.
  • If an update is available for your apps, you’ll see Update buttons next to them.
  • Click the button and the apps will be upgraded to the newer version.

Download the latest version from the official website

Maybe the 32-bit application you use on your Mac came from a website on the Internet. In that case, you might want to check out the app’s official website to see if a 64-bit update is available.

Just go to the app website and find a newer version of the app. If it is available, download and install it on your machine. Your existing app will be updated to the latest version.

Update apps from within the app

Many applications allow you to receive updates from within the application menu. This is true for apps like iTunes, Chrome, AppCleaner, etc.

App Cleaner's Check for Updates menu

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


If you haven’t already done so, go ahead and upgrade all your 32-bit apps to the 64-bit version if you still want them to run in the latest version of macOS. Failure to do so will cause your applications to malfunction.
