MacOS Upgrade Instructions

Before getting started with your MacOS upgrade, we recommend completing a number of system checks to ensure your upgrade goes smoothly.  If you run into any issues with the system checks or have questions, submit a Service Now ticket for assistance.

  • Check the status of your Crashplan Backup and ensure you have a complete backup. 
  • If you have an AFS client installed, it must be uninstalled before upgrading the operating system. To find out if you have it installed, open a finder window and navigate to Applications > Stanford > AFS > AFS Controller. If that path exists, you have an AFS client installed.  To uninstall:
  • Check for 32-bit applications, which are no longer supported under MacOS Catalina (10.15). 
    • Download and run Go64 tool to display your 32-bit applications.
    • Most application developers have Catalina compatible versions so it’s just a matter of upgrading your 32-bit app to the new version after you’ve upgraded to Catalina. Check the software vendor’s website for a Catalina compatible version. If there is no Catalina compatible version for your critical application, you must upgrade to Mojave (10.14) to be able to run 32-bit applications. If there are 32-bit applications that you do not use or no longer need, you may upgrade to Catalina.

Once these checks are completed, you can upgrade your own system to MacOS 12 (Monterey) or MacOS 11 (Big Sur) or MacOS 10.15 (Catalina) using Apple's upgrade instructions. If you are unsure which OS to upgrade to, submit a Service Now ticket for assistance.
