Apple Mac Operating System (macOS)

Usage and Licence Terms

  • Catalina is the latest operating system for Mac (will be released late September 2019) and is free to upgrade from Mac OS X Snow Leopard (10.6) or later.
  • In 2010 the University of Otago purchased Mac OS X Snow Leopard (10.6) licences for every Mac owned by the University, so all University owned Macs are licenced to run the latest compatible version of macOS.
  • Macs not owned by the University that came with Mac OS X Lion (10.6) and newer are licenced to run the latest compatible version of macOS.

macOS is available:

  • from on-campus in the Licenced folder on its-software server (smb://storage.hcs-p01.otago.ac.nz/its-software/its-software/Licensed/macOS). See Software Downloads for more information on accessing the its-sfotware server.
