Making the upgrade to Catalina

If you are considering upgrading an off-domain computer to Catalina, you should check the compatibility of any additional software you have installed. Please refer to Apple’s support article How to find 32-bit apps on your Mac

If all of your applications are compatible, you may proceed with the Catalina update. You can upgrade to Catalina by doing the following:

Apple Menu > System Preferences > Software Update.

As with all OS updates, we recommend that you back up your files before updating.
