View Full Version : Why clone only starts in safe mode?

Any ideas why I can only start in safe mode, when starting from a cloned hard drive on a different Intel Mac computer?

I regularly clone my MacBook Pro using SuperDuper's Smart Update option. Earlier this week I got an Intel Mac Mini for use if any emergencies arise. Both computers are running Mac OS X 10.4.11 (8S2167).

However, I am only able to start from either of my cloned external drives in safe mode. When trying to start normally from either cloned drive, instead of the normal loading and login screens, a nearly-black screen with some artifacts displays at that point.

This problem occurs when choosing the cloned startup drive after pressing Option at startup, or after selecting the drive in the System Preferences > Startup Disk panel and clicking Restart.

Both cloned drives are partitoned using GUID. One drive is a LaCie, the other an EZ Quest. The MacBook Pro starts up just fine from the same cloned drive.

Prior to updating to the Intel computers, I was always able to trade SuperDuper cloned drives between my G4 laptop and G4 Mac Mini. That ability saved my bacon more than once.

Any idea what is going here, or how to further troubleshoot the problems?

Thanks in advance. ...pt

Looks to me like the OS version that came with the laptop isn't compatible with the Mac mini, and (likely) vice versa...

Thanks, Dave, for the prompt reply.

I didn't realize that Apple had regressed to such OS version incompatibilities.

Based on that, I'll have to rethink my entire backup strategy. I'll probably use SuperDuper for cloning my main computer, and then occasionally use ChronoSync to synchronize the user files from my main computer to my emergency computer. And then hope my laptop doesn't get stolen or die unexpectedly.

In prior emergencies, it was much simpler when I could start and operate from a SuperDuper cloned disk for a few days, and then clone it back when my main computer was available again.

New hardware almost always comes with a 'special build' of the OS, and those builds aren't synchronized until the next release after that. 10.4.11 is a tough one, because Macs that came with 10.4.11 won't sync up until 10.5...

So at the point I get around to upgrading to 10.5, then I *should* be able to go back to my previous strategy - where a cloned drive from my laptop can start up my Mac Mini in an emergency?

That would be nice. However, while waiting for various programs to be upgraded for 10.5 compatibility, I may not upgrade for a few months yet.

Thanks. ...pt
