Process "accountsd" has over 500% CPU usage I'm on Catalina 10.15.6 on a MacBook 2019 (16-inch) and one hour ago after startup my mac started  with an extremely loud fan and overheating. As Im writing this even the typing is lagging behind.
Does anyone know why this is happening and how to fix it? I closed all apps running already and restarted several times, but nothing seems to work.
Alright after several unsuccesful restarts, Diagnostics (starting mac while pressing D), recovery and safe mode starts. I did a &quot;force quit&quot; of this accountsd process and after that, I made a hard shutdown of my mac (holding power button for 10 sec). Apparently this seems to reset the SMC of the Mac.
Now everything is working fine again. The accountsd process is at 0% CPU and I can use my mac in the usual way.
What I cant say is: Did the &quot;force quit&quot; of said accountsd process resolve the issue or the SMS reset?
For anyone having the same issue and finding this thread: I would try both and see if it works for you.
