Hello, I'm having an issue with my 2010 MacBook Pro. It started crashing a lot a couple of months ago, eventually even with kernel panics. Sometimes after a crash, during the next boot, it would display a progress bar below the Apple logo on the grey screen, similar to those you see during firmware updates. If that happened, the booting sequence would take a couple of minutes and would only finish after the progress bar was filled. It got progressively worse. One day I got a kernel panic, the same progress bar appeared during the next boot, but in the very beginning of the process the MacBook just shut down. I tried everything I could, including resetting PRAM/SMC, using a boot disk to check the internal HDD, fix permissions, etc. .. no use. So I reset everything from a Time Machine backup. Everything seemed to work (albeit with even more application crashes and a few kernel panics) for a few weeks, then BOOM - it won't boot again. This time I suspected a hardware issue, especially after taking out the internal HDD and using an enclosure to restore some files that were not backed up on Time Machine - when I plugged it in through USB the OS X complained that the disk couldn't be repaired and although files are accessible, the file system is read-only. So I got a brand new hard drive and did a full clean OS X reinstall. Two weeks later, the same issue It is very, very frustrating. I am NOT restoring through Time Machine another time. I want to find out what's going on here. Any suggestions? Since I can't boot I can't give you the full hardware profile, but it's something along the lines of a Core 2 Duo CPU @ 2 GHz, 8 GB of RAM, OS X 10.8.4. Any help or advice would be greatly appreciated. My warranty ran out so I really don't want to take this thing to a repair shop. Thank you!
