I just bought a 27” iMac. Recently, I make an attempt to install Windows XP through boot camp. But I was unable to register XP so I decided to go back to my old Mac OS, the problem is I cannot restore to its original OS. How can I fix this?

Which procedure were you trying to use to switch to the old Mac OS that you were using before? I will suggest that you just perform a clean installation of the Mac Os operating system again as opposed to trying to downgrading, if that is what you are trying to do.

The reason why you cannot be able to get the original Mac OS operating system when you try to downgrade is because there may be some windows XP files that are on the system and therefore you will need to get rid of them. Therefore, get a bootable Mac OS installation disc, and then perform a clean installation of the operating system.

As for the windows XP, you may just be having a wrong key, you could have tried others before you settle to switching back to the Mac OS.
