View Full Version : Boot Another Mac from my iMac SuperDuper Backup?

03-15-2008, 11:25 AM
I have used SuperDuper to back up my entire iMac system to an external USB hard drive. Then, I tested the external hard drive by booting from that disk. Everything worked perfectly ! ! !

Question: Can I take that external hard drive with my iMac full backup to another Mac (mini-mac, for example) and boot that machine from the drive? Or will hardware differences make this impossible?

Thanks for your comments.

1. 24" Al iMac, Intel 2.4Ghz Core 2 Duo, 3GB RAM, Leopard 10.5.2.
2. Mac Mini, 1.66Ghz Core Duo, 2GB RAM, Leopard 10.5.2

Should work fine.

Thanks for the assurance, Dave.

In fact, I tried it. I unplugged the USB connected Seagate Free Agent hard drive (on which I had performed a full bootable backup operation with my iMac) from my iMac and plugged it into my wife's Mac-mini, a much slower and less capable machine.

The little Mac-mini booted to the external hard drive, albeit slowly, and the user interface and program content appeared identical to that on my iMac.

In an admittedly limited experiment, I exercised four programs from my iMac on the Mac-mini and found that they all operated properly. In fact, I was able to bring up my TurboTax/Windows program that had been running on the iMac under Fusion 1.1 and Windows XP. TurboTax/Win functioned normally on the Mac-mini.

I did observe two anomalies, neither of which was a real issue:

1. When I attempted to play a song in iTunes, the program required that I agree to the Apple license for iTunes before it would launch; although I had long-since done so on my iTunes program on the iMac. When I acknowledge the license terms, the program launched and played normally.

2. When I launched Fusion 1.1 the program requested that I identify the location of the virtual machine, something it had never done on the iMac. When I clicked on the appropriate box, it found the VM and ran Windows XP normally.

All-in-all a very successful experiment.

I am impressed. :D

Glad to hear it worked as expected!
