I bought a copy of Tiger from ebay and apparently it will install only on an eMac. I have a G4. So, I did some extra looking around on ebay and found this-
This is an Original Apple Mac OS X 10.4 (TIGER) Full Version install/Restore DVD set. This is the set that ships with the new eMac. It is NEW OEM. Disks are labeled eMac. Disk set is in new, unused condition. It includes the Original Apple Mac OS X 10.4 Full install / Restore DVD's (2 Disks)-New, and Tiger Universal Install DVD adapted from Original Disks and Burned to DVD (not pictured) to allow installation of TIGER on any supported machine ( if you do not own an eMac).
So, I was wondering if it's easier to create new DVD's or try to return the DVD's to the seller.
