Suddenly the fan of my Mac Mini starts to run as crazy - Possible reason / elimination?
I found a solution for the problem, meanwhile.
Here's what worked for me: In the &quot;System-Preferences&quot; it was demanded to update the Apple-ID.


After doing so, I shutdown the machine. Then started it again.
The problem is now gone. The accountsd-process is still there in the processes-table, but the use of system-capacity is back to normal.
