A friend has a Mac Pro 8-core with 10.6.2. The hard drive is showing some issues so I would like to rebuild the installation from scratch on a new drive. I have an intel mac mini and I'm wondering if it is possible to create a new boot disk (via external firewire enclosure) and do all the updates and software installation (Final Cut Studio, Adobe suite, etc) on the mac mini and then simply drop the new drive into the mac pro. Or is the software installation hardware specific?
you shouldn't do that. first, there may be hardware problems due to difference in available hardware drivers if the mac pro is very new. also, if you do this the system will be identified everywhere including system profiler as mac mini. if you need to do it do it straight on the mac pro.
