SL Upgrade Disc does NOT work on Tiger

greenfestival · Nov 17, 2009, 03:53 PM

I own a MacBook Pro (Intel Core 2 Duo) with Tiger installed (10.4.11).

After reading several articles confirming that the Snow Leopard upgrade disc works on Tiger, I decided to purchase the $29 upgrade disc.

I pop the disc in, restart the computer, and (after choosing the English language option), am greeted with an error message:

"Mac OSX cannot be installed on this computer. This disc requires version 10.5 or later to be installed."

Anyone have any insight on this?

Thanks for the replies. Is anyone else having this problem? I find it hard to believe that i'm the only one.

you can't do an upgrade install. rather, backup all your information, and do a clean install. that is, boot the disk and use diskutility to wipe the drive. afterwards, you should be fine. this is because the default installation method on the SL disk is upgrade. you have to go through some hoops to find how to do a manual install.

The SL upgrade disk is designed to upgrade from Leopard not Tiger. It's only a problem if you don't have Leopard. Which the upgrade disk was designed for.
