A friend has a 17" macbook pro that wont boot, he as nstalling 10.4.9 and didnt realie e didnt have enough batter power to finsh and it shut off halfway through. He turn it on plugged it in and it finshed, restarted and wont boot. It gets a please turn of your compuer and restart message. I had a botoable backup of my macbook handy so booted of that, and copied he important files over. I looked in his harddrive and am seeing a mach_kernel in finder, which wasnt tere before. He is leaving on Wednesda so unless apple can do samme day service taking it in is really impossible. If preffered It would be nice to be fied tonight, I do not have the macbook pros install disks here I d however have my macbooks. Any ideas on how to fix it?
