Big Sur


Apple have announced they will be releasing their new operating system for Mac tomorrow, 12 November 2020.

Big Sur (OS 11) will be available to install from the App Store or, if you have automatic updates turned on, it will be downloaded to your machine automatically.

A number of applications that you may use at Royal Holloway are not supported on Big Sur and may not work correctly, including:

  • GlobalProtect (the VPN)
  • Sophos (antivirus)
  • Mathematica

SPSS, as it is reliant on a constant connection to campus via the VPN, will also stop working.

As with Apple’s Catalina (OS 10), there is no support for 32-bit apps, and these will also stop working if you choose to upgrade.

We strongly recommend that all Mac users check your commonly-used apps for compatibility with OS 11 before you choose to install it. If you have automatic updates turned on, you may wish to temporarily turn these off.

We are working with our suppliers to update apps that are not compatible with Big Sur, and will make these available as soon as possible.

A limited number of apps are available on the Windows Virtual Desktop, which can be used on Mac. You can check if your app is available here.

We will continue to update this page as more information becomes available.
