J'ai un MBA 2009 qui a un problème peu commun :
Le clavier et le trackpad cessent de fonctionner de manière aléatoire, parfois juste après le démarrage et parfois après quelques minutes. J'ai d'abord pensé qu'il s'agissait d'un problème avec le système d'exploitation, j'ai donc fait une installation propre de 10.8 Il a résolu le problème pendant une heure, puis il est revenu.
Je peux affirmer qu'il s'agit d'un problème provenant de ces dispositifs car l'ordinateur répond correctement lorsqu'il le contrôle avec ssh .
De plus, lorsque j'essaie d'utiliser un contrôleur usb, cela ne fonctionne pas du tout...
Je ne peux pas gérer un AHT parce que les disques SSD ont été entièrement effacés ( avant Je reçois le MBA)
J'ai isolé le journal correspondant :

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.
