Screensaver comes on randomly and prevents use in Big Sur and M1

We have a new MacBook Pro M1 with Big Sur 11.0.1 and already in a half dozen instances the screensaver has come on in the midst of using the computer, despite having screensavers turned off. When the screensaver appears randomly, the computer becomes unusable and has to be restarted to function again.


Anyone else have this issue?


Interestingly, I am the guest user of this MBP and this started to happen on my GF's side after I once turned the screensaver on in my partition. I have since turned my screensaver setting off but it still happens. I think this should provide a clue to the engineers, because it only happens in the main user partition.

I have filed a bug report on screensaver issue and just finished a call with Apple support. They have provided a solution and it did worked for me. Screensaver didn't show up yet. My machine is "MacBook Pro (13-inch, M1, 2020)".

Same here - I have screensaver set to never on both my accounts and it is still happening.

I will try to do some further testing with both having a single user logged in at a time and fast user switching disabled (which as I can see force the former anyways) to prove the workaround, but I think this still applies for the fix if being able to logged in via multiple users at the same time is a feature expected to work.

I've tried all fixes to this, updated to 11.1, nothing, the issue is still present. It is very annoying this one as it pops up randomly and typically in the worst of times. Hopefully with the next update we'll get a fix to this. I was trying to replicate what I was doing but seems it is just whenever it decides itself it is a good time to lock you out.

I am having the same issue with my brand new MacBook Air. I have spent over 6 hours on the phone with apple and even had the issue escalated to the senior tech who said even she was baffled. She had me bring it to my local apple store so they could completely wipe the computer and start fresh. I have had it back for 2 days now and it is still happening. Not sure where to go from here but it is very annoying especially since it happens in the middle of video meetings

I don’t have any accessories connected, so it may be a bit different to your use case. Did you touch any key after it is showing blank screen ? I am sure Apple will release a patch to fix this annoying issue. Until then, Hide your MBP from your wife. My 1st MBP is from 2006 and still works great even after I can’t upgrade OS for past 7 yrs. I am very frustrated as well for such a simple thing can’t work properly, but overall MBP experience is great and I see more pros than cons.

Thanks for that clarification.

Actually, the reason I tried my luck on the forum is because I did NOT succeed in getting to that point where you can file a bug report. I might be missing something here but the only thing I get from browsing the "Get Support" section is to be redirected to a chat or a phone call...

I did that with my HomePod problem and it did not go anywhere : When I asked "Could you please file a bug report on that" the only answer I got was "Sir, we are not at this point in the process... even if all the guy suggestions failed".


If you have an URL where I can open a good old support ticket like the others (tech companies) do, I would be pleased to help to get that issue fixed (as I'm sure many of others in this forum). I'm a support engineer myself, I kinda know how this work, so please... help me help you !


Regards.

i just purchased a MacBook Air and it is doing the same thing. I am having a very hard time with Apple support about this. I contacted them within the two week window to return the laptop and they have not resolved the issue with me. Every support person that I have spoken with has told me a different story and they keep putting me off and apologizing for my inconvenience. In fact, they are acting like they are doing ME a favor to look into the my “complaint.”


I need to know the answers to the following questions:


1) Have others had trouble returning new laptops? They are telling me the issue with returning the brand new laptop is related to my serial number.


2) Does this screensaver issue ONLY happen with the MacBook Air, because I am trying to decide if I should not replace this “lemon” with another Air that will have the same problem.


Thanks for your feedback about this. In closing I would like to add that mo one at Apple has admitted that this is a known problem, They are acting like this is an isolated instance; however, this thread leads me to believe otherwise.


Thanks!
