That might solve the issue until a patch comes along. In the meantime, if you encounter the problem, check to be sure the screensaver is turned off on all user accounts. It will likely not take long for Cupertino engineers to look into the situation. It might be that the screensaver activates on the secondary even if the primary profile is the one that is active.Īpple has not commented on the bug, but reports on the support forum have begun surfacing. MacRumors suspects it might be related to Big Sur's Fast User Switching feature. Several complaints mentioned having more than one user account on their device. Having it disabled on both user profiles solved the problem. I switched to my secondary account and disabled the screensaver on it as well. After disabling it again, I found the screensaver was still triggering after about 20 minutes. I have not encountered the exact issue with my 2018 Intel MacBook Pro, but I did notice that after installing Big Sur, the screensaver would activate even though I had previously had it set to "never." Checking the preferences menu showed that the install seemed to have reset that particular setting.
