Application menu bar is not responding on MI Mini

I have just upgraded to a new Mac mini with M1. I can not get a response when I mouse over a Menu Item in any Application. My old 2018 Mac mini is siting beside the new M1 and it works fine. Both systems are on Version 11.0.1.

I’ve went through all the notes and this is what I noticed. Using my thunderbolt cable was the problem. I switched back to my usb-c 4 and the menu is active and working. Looks like the same ongoing issue with 4K monitors or monitors connected using thunderbolt?

OK guys, I have a similar problem. I am using M1 mba with an external monitor on shell mode(with laptop closing up).When the problem happens, the menu bar will not respond, F3 for exposè will not work and any other functions concerned with exposè will not work.


For a quick fix, you could try to reopen the laptop shell and close it again. Or unplug the monitor cable whichever is easier. Hope this helps.

I just got this issue abt 10 minutes ago .I am thinking to restart as well but when i click the apple logo on tthe top left hand corner nothing happens. none of the buttons includint the apple logo is responsive. should i just press the power button behind the mac mini? force it to shut down.


Ook so when i press the power button to shut down i get a prompt on the screen if i want to shutdown restart etc. I can live with that

Same issue. Insane that something as important as the menu bar is rendered unusable. The only way to fix on my MBP M1 is to open the screen, which is a real pain because I have it in a holder vertically. Any time the screensaver kicks on and the screen locks is when I have the issue. So it either has to be:

  • Screen saver
  • Screen lock
  • Monitor going to sleep


My monitor is connected via thunderbolt as it is a Samsung that is also charging my laptop.


I feel bad for people on the minis, you would just likely be totally screwed. I tried to remove the com.apple.systemuiserver.plist file in my Library preferences and kill the SystemUIServer as some older threads suggested, and this did not help.

I just pull the connector from the rear of the Mac mini. I don't worry about the power to the monitor. I've had many long conversations with Apple support including escalations to senior consultants and they try to be helpful but they are not. BTW, I'm in that mode right now. My application menu for Safari does not even display, for other apps it is non-responsive! This seems like a pretty serious issue that lots of users are having. I have a Genius Bar appointment coming up for this and if I get any new insights I'll report.

It's April 22nd, 2021 and my MacBook Air M1 is exhibiting this behavior. macOS Big Sur, 11.2.3. I think it is only happening when I have the external monitor connected. When I'm using the external monitor I have the MBA closed. If I open the MBA, let the laptop's display and the external monitor finish sorting themselves out, and then close the MBA again the menu bar springs back into life.


I hope this is of some help to somebody!
