I'd like to install XP on my new aluminum MacBook, but I don't have the Leopard install disc that came with the MacBook handy with me. I left it in Texas, and I happen to be in Ohio until the beginning of the new year. The thing is, my family has their iMac install discs. Would these work fine? Normally, I'd try it without asking, but some newer drivers (like the unique trackpad of the aluminum MacBooks) cause me to hesitate.
