Macbook air freezes randomly
I've had my macbook air for 2 years and it will randomly freeze and need to be shut down by holding the power button for four seconds. This used to happen only about every 6 months but lately its been closer to once a week. Here's the report it sent to apple after the most recent shut down. Any ideas whats causing this?
