I just bought the Leopard family pack and installed it easily on my macbook. I can't get it to install on my powerpc g5 (2.5 gb ram, 200 gb hd). When I run the dvd, after it checks that the disc is ok, it says it's unable to install and suggests I run disk utility. I've run disk utility twice and it still won't install. My hard drive is striped which I think might be the problem. Any suggestions on what I should try next? Thanks a lot.
