I've written about my woes with my old iBook G4, but you'll be glad to know my new MacBook arrived today! Upon startup, I tried transferring my info using Setup Assistant via Firewire, which seemed simple enough, but it gave me the following error message (more or less): Cannot transfer info. OS X not installed on other Mac. Press 'Continue' to try again This is just not true. OS X is installed on the iBook. I tried several times to no avail. So I skipped that step and used Migration Assistant to do the transfer. Same error. I've read up on the Firewire Target Disk Mode, and as far as I know I don't need to update any firmware. But I don't think that's the issue, especially if it's saying that OS X isn't installed... I successfully transferred all my info from my My Book external drive, but now I've run into another problem. I now have 2 separate user accounts under my name - one has all my info from the old iBook and the other is just fresh. Is there a way I can merge the 2 accounts? Or should I just delete my new account and keep the iBook account? Sorry if it sounds confusing. The simple transfer process just didn't work out the way I was expecting, so I'm a little frustrated. Thanks!
