Hi, I'm running 10.5.6 on my unibody macbook pro and since DFU doesn't work with the latest update, I had to change some kext files to jailbreak my iPhone. I changed them back afterward, but now when I boot up, neither my keyboard nor mouse works. I can't even login! Unfortunately, I can't even boot up from safe mode from the restore discs as there's a cd in the drive that I can't eject. Please help! Thanks!!
