Apple’s latest operating system, macOS High Sierra (10.13) was released on 25th September 2017. The current supported version of Mac OS X deployed on university systems (10.12) has been tested thoroughly with the University software portfolio, network services and storage infrastructure.

We are currently aware of the following issues with 10.13 that you should consider before upgrading:

  1. Symantec anti-virus software should be upgraded to v14 before you update to macOS High Sierra.  This version is available at
  2. Older versions of Microsoft Office/Outlook may not work after the upgrade, the latest version is available at
  3. Following the upgrade, you may be invited to store all documents and desktop files to the iCloud Drive. The iCloud Drive, should not be used to store University data as this may be in breach of the University’s Data Protection Policy (section 3.7).
    Uncontrolled storage of University data on servers outside the EU, may also break data protection laws and could potentially lead to reputational or financial damage to the University.
    Information on how to turn off iCloud following the upgrade can be found here: How do I turn off the iCloud Drive when installing macOS Sierra on a University Mac?
  4. The High Sierra upgrade brings with it a mandatory upgrade to Apple’s new filesystem (APFS). Since this is not a fully mature technology, there may be unexpected issues, which can only be fixed by Apple themselves.

If you decide to upgrade to macOS High Sierra and serious issues do occur, unfortunately, your Mac may have to be wiped and rebuilt to the previous operating version.

iSolutions is currently working on a fully tested version of macOS High Sierra for University Mac computers over the next few weeks. We will provide you with further information once this is complete via SUSSED.
