If you use a gray installation disc, that is from an Intel-Mac, you will propably have no luck trying to install it on a PowerPC-Mac. The “Retail” version is good on both Intel and PowerPC, hence Universal. So, where’s the problem then? It is the kernel. The gray Mac-specific installation discs have a slim Intel- only Mach kernel on them, so it will simply say “This architecture is not supported by this kernel” or similar. All other things, all applications, are “universal” still. > Intel and PPC need different partition schemes, but the OS installed DOES > NOT CHANGE.

The first Intel-based Macs could use an APM formated HDD. The newer ones, that were shipped with 10.6 and newer, propably aren’t any longer. > If you're moving from a PPC mac to another PPC mac, as the OP is, then all > you need to do is be able to install the drive. Natuarlly, an IDE HDD will not be able to connect to a SATA bus, except when you use an adapter/converter. > Also EVERY DVD drive ever made will READ dual layer disks; after all, this > is how a 2 1/2 hour movie + extras are put onto a single DVD disk. As far as I remember this is true for DVD-R, but unfortunatelly not for DVD+R.
