Major macOS Catalina Catch

Apple is cutting off 32-bit app support in macOS 10.15.

Apple is cutting off 32-bit app support in macOS 10.15.

For all the new macOS 10.15 features, there is a major catch that you will need to adjust to. Apple no longer supports 32-bit apps on this version of macOS.

Apple started warning users about this with macOS Mojave, and now the cutoff is real. macOS Mojave is the last version of macOS that will run 32-bit apps.

Developers will need to offer 64-bit apps to run on macOS Catalina. You can check your apps to see if any of your apps are 32-bit.

  1. Hold the option key and click on the Apple logo in the upper left.
  2. Click on System Information.
  3. Scroll down to Software and Choose Applications.
  4. Click on the 64-bit menu option to sort by it.

Once you know, you can look for alternatives or reach out to the developer to see if they have a plan to support you with a 64-bit app this fall.
