Caution: ITS Recommends holding off on Catalina, the Latest Mac Operating System (OS)

October, 2019

Catalina, the latest Mac operating system, was recently released. ITS is asking the campus community to temporarily hold off on upgrading their Macs to this newest operating system. We want to test it and ensure that there are no conflicts and that the reported bugs in the beta release have been fixed. 

One of the biggest concerns with Catalina is that it will no longer allow 32-bit programs/applications to run. You will not want to upgrade if you are using any 32-bit programs until you can purchase a 64-bit version or alternate program(s). You can verify which programs are 32-bit by checking the system information. To do so:

  • Hold the option button on your keyboard, click the apple icon in the top left of your screen and then select “System Information…”
  • A screen will appear. Select “Applications,” located under the “Software” section. This is where all of your applications are listed as well as a column that will report if an application is a 64-bit app.
  • If there is a “No” in the “64-Bit (Intel)” column for the application, then that software will not run on Catalina.

Another thing to keep in mind: If you do upgrade to Catalina, prior to ITS approval, and have issues, there is no easy way to rollback to Mojave. If, for any reason, you need to downgrade, Mojave will need to be re-installed on your machine; meaning, your data will have to be backed up and your drive will need to be wiped.

ITS will send out another announcement once we can ensure Catalina will work for the majority of campus applications. Until then, we strongly recommend that you hold off on upgrading to Catalina.
