Thanks, unfortunatley I bought it from the Apple store in the UK and it didn't come with any disks :-(
I have access to other computers, is there anywhere I can legally download an ISO image?
Sorry, I find that hard to believe. Especially, if you purchased your computer from an Apple Store. Doesn't matter which country an Apple Store is located, all Macs up to Snow Leopard came with 2 system discs.
Replacement System Discs can be obtained from Apple's Customer Support - US (800) 767-2775 for a nominal fee. You'll need to have the model and serial number of your Mac available.
If you're not in the US, you may need to go through the regional Apple Store that serves your location to find the contact number - http://store.apple.com/Catalog/US/Images/intlstoreroutingpage.html
Ok I will have to contact the apple store. I bought it mail order in the UK, I still have teh box it came in, with all the other bits of card and plastic bags, there were definitly no CD's/DVDs with it.
I remeber at the time thinking that was odd, but most Windows systems don't ship with them now either, the media is on a hidden partition that you can acces during boot and I assumed it was the same here too.
But thanks anyway.
