Upgrade your Mac from OS X Yosemite to macOS Sierra

All University Mac users are strongly advised to upgrade from OS X Yosemite operating system to macOS Sierra (v10.12.6), as soon as possible, as Yosemite is no longer supported by Apple. The upgrade will help to ensure that Macs have the latest security, features, and remain compatible with other University systems.

If you are currently running OS X El Capitan (10.11.x) or macOS Sierra (10.12.x) then you do not need to do anything. Find out which operating system version you are currently using.

  1. Go to Mac Self Service
  2. Under Categories, click on OS Updates*
  3. A MacOS Sierra icon should appear
  4. Click on Install (this may take a while to complete)

*this will appear if your Mac is compatible with the upgrade.
