TECH ALERT: Delay macOS Big Sur Upgrades

November 11, 2020

Faculty and professional staff with Drexel-provided Macs should NOT update to macOS Big Sur, which will be released on Thursday, November 12. Drexel IT must first test critical Drexel software and systems—including Sophos Safeguard, our data encryption and security software—to ensure compatibility.

When an operating system is updated, some applications break and need to be updated to regain their compatibility. This is the case with macOS Big Sur. Once again, we strongly recommend that faculty and professional staff DO NOT upgrade, even though some Drexel-provided macOS users might receive prompts or see the update as available. As in years past, we anticipate approving the new Operating System early next year.

Currently, at Drexel we support macOS Mojave and macOS Catalina. Drexel-provided Macs can upgrade to macOS Mojave or Catalina, presuming the device was manufactured after 2013. You can upgrade to the most recent, approved version of macOS by following the instructions available in our RemedyForce Knowledge Base.

If you have questions or concerns, or inadvertently updated your Drexel-provided Mac computer, contact the IT Help Desk at 215.895.2020 or Information about how to upgrade to macOS Big Sur, once it is safe to upgrade, will be available on our Web site at We encourage you to visit and check our Web site often for updates.
