  • macOS 10.15, 10.14, 10.13 (Catalina, Mojave, and High Sierra)

For Students and Faculty/Staff non-Geneseo Computers

If the installer tells you that your operating system is too old, you will need to upgrade your OS to a supported version (preferably the latest version). Both Microsoft and Apple have instructions on how to do so:

For Faculty/Staff Geneseo Computers

If you have a computer provided by the school, upgrading your OS version depends on what kind of OS you have:

  • For Windows, upgrading the Windows 10 build is easy. You can either find the latest build in Software Center or download it from Software at Geneseo. This installation will take some time (around 40 minutes on average), so be sure to run it when you won't need your computer for a bit. If you have Windows 8.1, 8, 7, or older, contact your department's Technology Support Professional (TSP) for assistance.
  • For macOS, the latest OS version provided by Geneseo is available for download in Managed Software Center. The installation will take around 40 minutes, so make sure to run it when you won't need your computer immediately.

If you cannot get a supported OS to install, contact your TSP for assistance.
