Hello,

It is the third time that my MacBook Pro is blocked (no mouse or keyboard) and that at the same time an alarm sound beeping like an ambulance occurs...

I wonder why and I'm afraid of what could append next.

Do you know what this means ?


MacBook Pro (13-inch Late 2011), Mac OS X (10.7.4)

Alancito has provided the appropriate Apple support article for the Apple Hardware Test.  For your MBP, a disk is not necessary.  Press and hold down the D key when you start your MBP.  It will do no harm to your machine.

 

Ciao.

Run an Apple hardware test.  The only audible alarms that I am aware of indicate RAM problems.

 

Ciao.
