Fehler auf kernel.log… wie behebe ich sie?

Mein Mac funktioniert anscheinend einwandfrei, es gibt keinerlei Abstürze, aber mein kernel.log ist voller Fehler und das beunruhigt mich, da ich es nie mit solchen Nachrichten gesehen habe. Dies ist ein Beispiel von heute, da ich die Maschine gebootet habe:

Wie Sie sehen können, können viele Dinge nicht geladen werden, Fehler aller Art ... Wie kann ich sie beheben und diese Nachrichten verschwinden lassen?

Dies ist Mac OS X Lion 10.7.4, der auf einem iMac Mitte 2011 (iMac 12,2) ausgeführt wird.

Vielen Dank.

Die Fehler, die ich in diesem Protokoll sehe, haben mit Kexts (Kernel-Erweiterungen) zu tun.

Versuchen Sie, im abgesicherten Modus zu starten (beschrieben in Apples HT1564 ): Halten Sie die Umschalttaste während des Startvorgangs gedrückt . Der Computer lädt dann nur bestimmte Kernel-Erweiterungen.

Wenn dies zu weniger Fehlern im Protokoll führt, liegt möglicherweise ein Problem mit dem Kernel-Erweiterungscache vor (der meines Erachtens im abgesicherten Modus umgangen wird: siehe TS1884 , obwohl dies nur für 10.5 als relevant markiert ist).

Wenn es anscheinend ein Problem mit dem Kext-Cache gibt, können Sie ihn meines Erachtens sicher löschen, /System/Library/Caches/com.apple.kext.caches/und er wird neu erstellt, wie in dieser Frage und Antwort von superuser.com erläutert. Aber ich würde in diesem Szenario etwas mehr Nachforschungen anstellen, um dies zuerst zu überprüfen, da es sich bei dieser Frage um 10.6 handelt.
