  1. Running Big Sur. I held the shift key down on restart but I have no indication that I am in safe mode. Computer worked the same as always. I started having this issue a while back on this computer only. I can sign in with my other apple ID and messages and facetime work fine. Now, I sign in and it looks like I am on then 10 seconds later I get the sign on screen again.

    I will keep searching the web. Thanks.

    • With Safe Mode it should say Safe Mode(or Boot, I forget) on the upper right hand corner of the log in screen. If you have a firmware password set it probably won’t do a safe boot.

    • Having this exact issue. Sign into messages, it opens for about 10 seconds and then quits and gives me the login screen again. Also running Big Sur on a MacBookPro. Did you find a solution?
