Sooo basically I have done this thing using my Mac mini 10.5 discs and edited the osinstall.mpkg so it would work on my Imac g4 which I later transfered on to my USB using ccc so everything was good until I got to the installation part where it told me to clean me discs but I have used a bootable USB so now I kind of dont what to do ...... Just wondering if it would work me changing the osinstall.mpkg on the actual discs and using it like that or not?? Any help would be great!!
