Seit einigen Wochen startet mein MBP 2020 (MacBookPro16,2) im laufenden
Betrieb immer wieder neu, d.h. der Bildschirm wird schwarz und das
System (macOS 11.6.4 (20G417) Big Sur) wird neu gebootet.
Dieser Vorgang tritt anscheinend nie auf, wenn ich gerade aktiv am Gerät
arbeite sondern immer dann, wenn das Gerät für einige Zeit nicht benutzt
wird, auch im Ruhezustand.
Im Syslog habe ich nichts gefunden, was auf eine Ursache hindeutet. Das
hier sind die typischen letzten Zeilen vor dem Reboot:

Auch das Abstöpseln aller externen Geräte brachte keine Abhilfe. Die
Hardwarediagnose findet keine Fehler.
Irgendwelche Ideen?
