Ho un MBA 2009 che ha un piccolo problema non comune:
La tastiera e il trackpad smettono di funzionare in modo casuale, a volte solo dopo l'avvio e talvolta dopo pochi minuti. All'inizio ho pensato che fosse un problema con il sistema operativo, quindi ho eseguito un'installazione pulita di 10.8 , ho risolto il problema per un'ora e poi è tornato.
Posso affermare che si tratta di un problema proveniente da questi dispositivi perché il computer risponde correttamente quando lo controlla con ssh .
Inoltre, quando provo a usare e controller USB non funziona affatto ...
Non riesco a eseguire un AHT perché l'SSD è stato completamente cancellato ( prima ottengo l'MBA)
Ho isolato il registro corrispondente:

Will attempt to recover by breaking constraint
<NSLayoutConstraint:0x7ffdf8cb22e0 H:[NSTextField:0x7ffdf8cb1fa0(184)]>
Set the NSUserDefault NSConstraintBasedLayoutVisualizeMutuallyExclusiveConstraints to YES to have -[NSWindow visualizeConstraints:] automatically called when this happens. And/or, break on objc_exception_throw to catch this in the debugger.

L'ultimo viene ripetuto molto e la disabilitazione del centro notifiche non ha funzionato. Proverò EFI.
