I want to do some slightly dangerous testing, testing an install package I've written, so I've got an external drive, and I want to make it a bootable OSX disk, then I can boot up on the external, do my install, and if it screws things up, it doesn't actually affect the usability of my machine.
The problem is that when I stick the disk that came with my computer (It's actually another computer in the office, but they're both minis) in and try to run the installer, it says "You cannot install OSx 10.6 on this computer". Now, the computer is ALREADY running 10.6, so that's a kind of silly error message...
It does this when I boot to the DVDRom as well.
Am I doing something really really dumb? or what?
