I want to upgrade to Mountain Lion. I have 10.5.8 OS X now. The Software Update says there are no updates.But I need to update to the next level in order to be able to download Mountain Lion.

So I go to Apple Support - they ask for my serial number - i type it in - it says "invalid".


So now what? I'm stuck and Apple Support won't talk to me without the serial number.

    There has never been a free upgrade from 10.5 to 10.6 Snow Leopard, so Software Update is reporting the correct information. Snow Leopard was a $30 upgrade, which you may be able to still get by calling Apple, in the US, at 1-800-MY-APPLE. Ask if it's still available from the legacy products list. Since Mountain Lion was released, it's been pulled off the Apple online store site. Or check Amazon or hardcoremac.com.
