The following question was asked on another forum, and the answer has me wondering... What are your thoughts about this? Question: Do you really think an Intel based Mac will boot from a PPC operating system? Answer: Yup. I've got a PPC G5 iMac iSight 20" on my wife's desk right next to mine, and it's USB CCC backup drive, both with Leopard 10.5 8 with APM format of course, and they are both bootable with my SL Intel 24" iMac. So yes, I know it works. But thanks for your concern. And what's even more interesting to me, is that both have been 'trimmed' of surplus Intel code etc. using Monolingual, so they are both OS X PPC code only. Not too bad Apple.
