✓ macOS Catalina install restriction lifted on October 22 2019 for college-owned computers.ITS has been testing macOS Catalina beta version since its release on September 2019. Catalina is the first version of macOS to exclusively support 64-bit applications which means that some of your critical and favorite programs may no longer work with this new version.
We recommend that you only upgrade if your computer has at least 18.5 GB of available storage space and a minimum of 8 GB of RAM. Before upgrading, make sure you have a backup plan and set aside plenty of time for the installation to complete.
If your Mac is currently running macOS Mojave, and you have not installed specialty software, it most likely meets all of these requirements and you are safe to upgrade. Upgrading to macOS Catalina is not required.
✓ Have a backup.ITS strongly recommends backing up your data. Once you upgrade, there's no going back to retrieve any lost data. Back up your data to your Google Drive Backup & Sync, H Drive, Time Machine, or CrashPlan.
✓ Check software compatibility.What are the most important software programs you use every day? The latest versions of programs such as Microsoft Office and Google File Stream are known to work great with macOS Catalina, but some specialized software may need patches or paid upgrades before they work. If you aren’t sure, contact the ITS Help Desk at email@example.com. Faculty members may contact their Academic Information Associate. RoaringApps compatibility checker may have more information.
The following applications have been tested and launch successfully. ITS cannot test every function in these programs: ATLAS.ti, Citrix, Google Drive File Stream, Mathematica, ChemDraw, CrashPlan, GlobalProtect.
