Can I use a Mac os x 10.6.6 that came with a newer iMac to install it on another one?
If you have the gray installation CD you probably won't be able to do it because they are machine specific, but its worth a try. If you boot from the CD &amp; it is not compatible with the machine it will just tell you to press the power button to turn off your machine. Then just boot normally &amp; eject the CD, no harm done.
