I am currently running 10.4.11 on a G5 1.6 GHz Mac. I am trying to upgrade to 10.5 Leopard. I have manually backed up my machine to an external drive. When I try to boot off the Leopard disc...it boots, I'm able to select language, but then it says OS X can't be installed on this disc. My Mac is formatted as Mac OS Extended and has the current Firmware. I have run the Disc Utility from the start up disc and fixed permissions and any disc repair options and it still states that OS X can't be installed on this disc. What am I missing?

Any Help??

Thanks!
Michael

Where did you get your Leopard DVD? Is it an OEM version (gray label, I believe) that shipped with a Mac? If so, those are machine-specific.

They are gray disc...because I can't find anywhere to purchase the Leopard OS only Snow Leopard. My non intel mac will not run Snow Leopard. Can I partition my disc with single partition...will that work.

Lots of places where you can purchase a retail version of Leopard. The only drawback is that the retail version of Leopard has risen in price like what Gold is doing on the open market right now. :Angry-Tongue:

I suggest you stick with Tiger or bite the bullet and purchase Leopard from Amazon, NewEgg, etc. for around $225.00 new.

Regards.

I agree with chscag. Tiger is perfectly capable and will continue to run all of the software you currently have. "If it ain't broke, don't fix it." :)

No, you can't use that disc. They gray label ones are specific to the Mac model they shipped with. It won't work on yours. At all.

The retail version of Leopard is still readily available, though chscag is right… the current price for it on Amazon is insane. You can get a better deal off eBay, but be VERY SURE you are getting the "retail" version.

Hint-hint. If you absolutely must upgrade from 10.4, the tip for finding retail discs.

Look at the picture. If they have a space scene on them, they're retail. If they're gray, they're OEM for a particular Macintosh.

No, no, no, no! Sorry to disagree so "loudly". You must not have seen the many posts about getting Leopard from Apple by phone order. I think the most recent one I read said for $89 US. But, you have to call. You can't order online, or find it in a store. One person said you might get a negative response (We don't have any.) but if you're really nice and plead with them, they relent.
