I have searched and searched the internet, and have found similar issues, but I've yet to find a solution. So, hopefully you guys can help. I have an iBook G4. Recently, I broke it (we won't get into that). I found another iBook G4 on eBay and bought it. Now, before I broke my first iBook, I cloned the drive to my Western Digital Passport Studio Edition via SuperDuper. When I got this new computer, I plugged in the Passport (via Firewire) and booted up. I pressed the option key and was asked what I'd like to boot from, but there was only one option: the internal hard drive. So, I let the computer boot as normal, then went to Startup Disk in System Preferences. The computer had recognized the Firewire drive when it was booted up, so I just selected that drive. I restarted the computer, and was greeted by a little Finder icon with a question mark over it. The computer proceeded to bootup normally. What am I doing wrong? The external drive is formatted as Apple Partition Map, and the computer clearly recognizes it once it's fully booted up. I've tried doing this on my MacBook Pro, and it works fine. Tried it on a normal MacBook and it works fine, too. I'm thinking that the whole PowerPC thing is causing the issue. Any suggestions?
