Hello All, I've got a MacBook Air that is having very random lock up issues. Here are the specs: Model Name: MacBook Air Model Identifier: MacBookAir2,1 Processor Name: Intel Core 2 Duo Processor Speed: 1.86 GHz Memory: 2 GB The MacBook will just lock up no matter whats running, whether its just Safari and iTunes open, or just Safari, or just PhotoShop, or just iTunes. Whether its hooked up via wifi or via a network cable. What I've done so far is this: - Wiped Hard Drive and reinstalled Snow Leopard - No issues with install - Ran Disk Utility to Repair and Verify the hard drive - Came Back Green - Ran Memtest with 6 loops to test the memory - came back green - Used Onyx to test Hard Drive and clean system - Temperatures are fine while running, computer doesn't even get warm I was thinking it might be the video but there's no flickering at any time, I can stream video or run a local video in fullscreen just fine without any issues. The last time it locked up, the system.log said it was trying to write something to the Safari cache and then it showed my "unexpected shutdown" from me turning off the computer to boot it back up... Is there anything else I can test or try? I've been contemplating trying to find/purchase an SSD for the Air since it has the factory 4200rpm disk drive in it. Looking for recommendations... Thanks.
