Q: My younger sister has just got a new Macbook and I am trying to use the Install disk to put Leopard onto my older computer. Can anyone give me any helpful advice?
A: Okay, STOP!!! The disks that come with the MacBook are for that MacBook only, if you try to install them on another computer one of two things will happen: 1. If the older computer is an Intel based Mac you'll get an error telling you that this install disk doesn't belong with this computer and it will stop the install. (there's no way around it, it's coded to the chipset of the MacBook only) OR 2. If the computer is not an Intel based Mac (ie: G5, G4 or G3) there's a good chance you'll screw up the file structure resources on your Hard drive. If this happens you'll need an experienced tech to fix it (and it the data could be unrecoverable) In order to install Leopard on your older machine (assuming it meets the system requirements) you need a full retail version of Leopard. I've seen at least a dozen machines come into my shop with the problem described in #2 above, all people who bought MacBooks or MacBook Pro's and tried to upgrade their system on an older machine using the disks that came with the new laptop. Most of the were recoverable, but all of them ended up spending more money having us fix it then they would have by just buying a retail copy of Leopard.
