Tengo un MBA 2009 que tiene un problema poco común :
El teclado y el trackpad dejan de funcionar aleatoriamente, a veces justo después del arranque y otras veces después de unos minutos. Al principio pensé que era un problema del sistema operativo, así que hice una instalación limpia de 10.8 El problema se solucionó durante una hora y luego volvió a aparecer.
Puedo afirmar que es un problema que proviene de estos dispositivos porque el ordenador responde correctamente al controlarlo con ssh .
Además, cuando intento utilizar y controlador usb no funciona en absoluto...
No puedo ejecutar un AHT porque los SSD se han borrado por completo ( antes de Me dan el MBA)
He aislado el registro correspondiente :

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.
