I have an Power Mac G5 with tiger on it, an iMac with Leopard on it and my MBA with Lion... I wanted to reinstall the original OS on the imac and the CD is dead.... So now's my question! Instead of running around and trying to get another DVD form a shaddy vendor, I tought I could take a one year membership with ADP, Mac developement and get Leopard for the G5, Snow leopard for the iMac and Montain Lion this summer for my MBA... Is that possible ? (getting the OS from Apple, and not renewing my subscription next year) Thank you!
