MacOS Big Sur Conflict with Sophos
Apple is releasing the latest operating system—MacOS 11 or Big Sur—for Macintosh computers Thursday, November 12. At this time, Sophos is not compatible with Big Sur.
If you are using Sophos Home or using the Sophos Endpoint Protection campus license for antivirus/anti-malware, make sure that automatic updates are turned off on your Macintosh computer to avoid issues.
Depending on your computer, you may find automatic updates in App Store > Preferences
Or it may be in System Preferences > Software Updates
When you find either of the above checkboxes, if it is clicked on (as above), click it again to turn automatic updates off.
After Sophos updates to be compatible with Big Sur, you can turn automatic updates back on and install the new operating system if you wish to.
