Hi everyone! Can somebody advise me, please...? I own a Black MacBook 4,1 (late 2008) with OS X Leopard (v.10.5.8) installed. I am experiencing problems with the hard drive, which requires the Installation Discs to sort it out, but I don't have the Installation Disc Set. I was wondering what would be the best, most effective remedy for this problem? Would it be possible / recommended to backup then format the hard drive and do a fresh, full install using OS X Snow Leopard 10.6? Would this be possible and would it sort out the problem/s? If you have any other ideas or recommendations I would be most grateful. Many thanks in anticipation. Sincerely, Nigel.
