Apple’s latest operating system, macOS Mojave (10.14) was released on 24 September 2018. The current supported version of Mac OS X deployed on university systems (10.13) has been tested thoroughly with the University software portfolio, network services and storage infrastructure.

We are currently aware of the following potential issues with 10.14 that you should consider before upgrading:

  1. Symantec anti-virus software should be upgraded to v14 before you update to macOS Mojave. 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. macOS Mojave is the last version of the Operating System which will support 32-bit applications, and so you should start to identify and move away from them as soon as possible. They can be identified in two ways:

1. When you run a 32-bit application for the first time on Mojave, you’ll receive an “application is not optimised for your Mac and needs to be updated” warning.
2. Alternatively, from the Apple menu, choose “About This Mac”, then click the “System Report” button. From the system report, scroll down to “Software” in the sidebar, then select “Applications”. When you select an individual application, you will see a field titled 64-bit (Intel). “Yes" indicates 64-bit; “No" indicates 32-bit. If you're already using macOS Mojave, select Legacy Software in the sidebar to see all applications that have not been updated to use 64-bit processes. (from the Apple Support Knowledgebase)

More information about the transition away from 32-bit applications can be found on Apple’s website:

iSolutions is currently working on a fully tested version of macOS Mojave for University Mac computers over the next few weeks.
