macOS Big Sur Compatibility Issues with UCLA Health Tools

  • February 11, 2021
  • News

Apple's latest macOS, Big Sur, is publicly available; however, our teams have identified compatibility issues with UCLA Health's commonly used applications. We strongly recommend not upgrading your devices to Big Sur until the third-party applications have been updated by their developer. All UCLA Health IT-managed macOS devices will also not be upgraded.

We also recommend not purchasing the new MacBook devices with the Apple Silicon M1 chipset. This device only works with the macOS Big Sur, which is currently not compatible with commonly-used applications.

Our teams will provide more information once testing has concluded to ensure compatibility issues have been resolved.

Security Exceptions

*Please note we are no longer providing security exceptions for devices on Big Sur.

If you were granted an exception prior to February 2021, please update OnGuard and Global Protect VPN on your device. You can find the links to download below.
