Die andere Art einer 'defekten' System.keychain

Gestern nachmittag sah mein System.log noch so aus=-O

Nach dieser Terminal Eingabe (von macosxhints

sudo systemkeychain -vfcC

sieht mein system.log nun so aus
Apr 24 19:30:21 G4-17 loginwindow[105]: Login Window Started Security Agent
Apr 24 19:30:36 G4-17 kernel[0]: PB5_1_PlatformMonitor::registerConSensor - type 3, csi 2, subsi 5
Apr 24 19:30:41 G4-17 diskarbitrationd[38]: SystemUIServer [145]:22531 not responding.

Nun mußte ich nur noch das entsprechende Passwort des gewünschten Aiport-Netzes nochmal neu eintragen.

NB Die System.keychain wird bei einer Initial-Installation und bei jedem subsequentiellen update neu angelegt.
Kann aber auch mal defekt sein.
