Warum stürzt mein Mac immer wieder ab?

(Ich muss das schnell erledigen, da ich denke, dass mein Mac wieder abstürzen wird.)

Mein Mac stürzt immer wieder ab. Es begann, seit ich Adobe Acrobat Pro installiert habe (seitdem habe ich es entfernt), aber es hat möglicherweise nichts damit zu tun. Selbst nachdem ich es entfernt habe, stürzt es immer noch alle paar Minuten ab.

Hier ist das neueste Panikprotokoll von Console:

Eine Ausnahme bei der Maschinenüberprüfung ist normalerweise ein Hardwarefehler. Wenn Sie Glück haben, handelt es sich "nur" um einen RAM-Fehler. Wenn Sie großes Glück haben, können Sie diesen beheben, indem Sie Ihren RAM neu einsetzen oder (glücklicherweise, aber nicht sehr glücklich) eine fehlerhafte RAM-Karte ersetzen. Wenn Sie Pech haben, könnte es ein Motherboard-Problem sein.

Erstellen Sie auf einem anderen Mac ein startfähiges externes Laufwerk (USB, FireWire oder Thunderbolt) mit einer sauberen Installation einer Version von Mac OS X, von der Sie wissen, dass Ihr ausfallender Mac dies unterstützt. Schließen Sie dann das Laufwerk an den ausfallenden Mac an und starten Sie von diesem. Wenn die Ausnahme für die Maschinenüberprüfung weiterhin angezeigt wird, liegt wahrscheinlich ein Hardwarefehler vor.
