So as the title explains, since last Friday I've been trying to figure out why my Macbook Pro started getting stuck on the boot screen with the spinning gear. Sometimes a progress bar appear and it fills like 1/20th of the way and goes back to the spinning gear. However, if I boot into Windows 7, it works fine. I tried using the Snow Leopard install disk to get into disk utility and it won't even boot from cd (For reference, I tried the hold-c command to boot into the cd). The I tried resetting the PRAM, the SMC reset and the fsk thing, no bananas. I have this Macbook Pro since June 2009. I'm shot of ideas, if you guys have no idea what's wrong its a call to Apple, or a meeting with a "Genius" ugh. Thanks and sorry for the long read.
