macOS Catalina upgrade not recommended for University Macs

If you are using a University Mac, we do not recommend upgrading to macOS Catalina, whilst testing takes place. In preparation, you’ll need to consider any older ‘32-bit’ apps (e.g. Photoshop CC v2018), you are using, as they will no longer be supported.


macOS Catalina (version 10.15) is Apple’s new Operating System for the Mac. IT Services strongly advise that you do not upgrade your University owned Mac. There are known compatibility issues with Adobe Photoshop and there may be other issues with University applications and IT systems.

What can I do to prepare?

Before you upgrade to macOS Catalina you will need to consider any older ‘32-bit’ apps, you are using, as they will no longer be supported. You may have already seen notifications appear when you run apps, such as “App” is not optimized for your Mac and needs to be updated.

Apps like Office 2016 are already 64-bit versions, so will continue to work as before. This article explains more and how to prepare for your upgrade:

For now, identify any older applications you use. More information and support will be provided following testing of macOS Catalina.


This release of Apple’s new Operating System has not yet fully been tested with the University’s applications and IT systems. Further testing will be carried out over the next few weeks and we’ll communicate our findings in due course.
