I've got a brand new Macbook Air 2012 with 8GB ram, 512 GB SSD, Core i7. I transfered all my files, apps, etc from my old Macbook Air. And last night it froze twice in an hour. I wasn't doing anything fancy, CPU load was very low. The freeze was full: no beachball, no crash screen, nothing, just everything stopped working and what was on the screen stayed there, frozen in time. It was a bit warm in my home, 85 F or so, but I wouldn't expect that to freeze my brand spanking new machine. But, it hasn't happened since I've been using it in a cooler environment (70 F) as yet. Anyone else having a similar problem?
