Checking for 32-bit apps on an individual machine. I'm not sure how useful this would be to Mac admins, but you can check for 32-bit applications on a single machine by going to System Information.app. Then scroll down on the left side to find, under Software, Applications. It might take a while for the list to load. Once the list is loaded. Developers of Mac applications have known about the transition to 64-bit apps for several years, and most modern applications have or will be updated to work with Catalina. However, there may be some old or no-longer developed apps that are 32-bit only. More reading about macOS Catalina & 32-bit apps: 32-bit app compatibility – Apple support.
MacOS Catalina does not allow 32 bit applications to run. In order to upgrade you will need to find updated or alternative software to meet your business requirements. To see what software on your Mac might be 32 bit you can perform the following steps:
- Click the apple icon on the top left of your computer screen and select 'About this Mac'
- Click the 'System Report...' button on the screen that pops up.
- Click Software then Applications. You will see a column for 64-bit (Intel). Sort by this column and look for applications that say 'No.'
Any applications you find may have a newer version available from the software grid. For the most up to date information on versioning requirements please visit our MacOS Catalina known issues page.

Mac Os 32 Bit
Apple began transitioning to 64-bit hardware and software technology for Mac over a decade ago, and all modern Macs now include powerful 64-bit processors that can run advanced 64-bit apps. These apps can access dramatically more memory, enable faster system performance, and take advantage of technologies that define today’s Mac experience, such as Metal graphics acceleration.
Apple has been working with developers to transition their apps, and in 2018 Apple informed them that macOS Mojave would be the last version of macOS to run 32-bit apps.

When you attempt to open a 32-bit app, you will see an alert that the app is not optimized for your Mac, or that the developer needs to update it to work with this version of macOS.
If you haven’t upgraded to macOS Catalina, you can still open and use the app, but you should check with the app developer for a 64-bit version that also works with the latest macOS.
How to find 32-bit apps on your Mac
System Information can find 32-bit apps that are installed on your Mac:
