I just bought two iMac's at an auction, they were both wiped clean before the sale. The problem is when I turn them on I'm getting a screen with an icon of a folder with a question mark. So the guy wiped them but didn't reinstall it, or so I believe.
I did not get any of the disc's for the computer because it was a school sale, so I have no idea how I can installed the system so I can use them. I do have a Macbook Pro running Mac OS X version 10.6.8, however the disc that came with it didn't work on the large iMac's, which I figured it wouldn't.
My question is what do I do at this point? Is there a way to start them, Do I need to buy a disc?
