Hi all,now i have an old g4 powermac and i have recently purchased some imac grey 10.4.4 discs,when trying to install these dvd's i get a kernel panic error at the very first start up screen,the os im using now is from grey ibook cd's 10.2.1 and i hav'nt any problems with this,so is there any way i can install these dvd.s containing 10.4.4 on my machine or did i waste my money!
