eMac 800 MHz and Leopard

You could force it to run once you upgrade the RAM, but it would be unbearably slow ... at least for me.

Short Answer: No, you can't.

Long Answer: Technically you can, but it will require hacking the installation disk, and dealing with a slow unfriendly computer.

I think you'll be better off with Tiger.

+1 for Tiger.

Really, yes, you can get this to run. But you're going to have a disappointing experience.

I get frustrated with it on my 1.25GHz eMac w/ 1gig. I can't imagine it on your machine. Tiger would be better suited as I know mine ran much smoother on it.

A member on this forum installed Leopard on his 500 MHz Titanium PowerBook, and I recall him saying it ran Safari and iTunes decently, but not much else. Your machine would be better, but don't expect it to run more then 2 or 3 programs at a time.

It's not really going to be as terrible as some people suggest. I run Leopard on a 1ghz eMac daily and for email, web browsing, IM and other light tasks it's perfectly fine.

You can install 10.5 pretty easily on the 800mhz by spoofing the clock speed in open firmware.
