Hallo MTN Foren-siker,
Ich weiss nicht mehr weiter und suche eure Hilfe.
Der Macmini6.1, i5, 8GB, SSD, nacktes System 10.13.6 war schon beim ISP. Der hat ihn ein paar Tage laufen lassen und nix gefunden. Danach lief er bei mir ca. 1Monat lang bis zur gleichen Kernel Panic wie zuvor.
Nach dem Einbau eines anderen Netzteils lief er dann wieder einige Zeit. Jetzt startet er nur noch mit gedrückter Umschalttaste und liefert den angehängten Panic Report.
Vielen Dank im Vorab.

Hallo,
Mein Thread war so schnell in der Versenkung verschwunden.
Hat denn keiner einen Rat oder eine Idee aus welcher Richtung die Panic entsteht?
Egal welche SSD oder HD extern oder intern und welches System von10.9 bis 10.13,
dies ist immer gleich :
