Thanks Rain. Where does it say I'm using Leopard?
I looked in the 'apple/about this mac/software' and all I see is, Mac OS X 10.5.8 (9L31a).


Thanks Rain.

I don't think you'll see it on the actual computer - at least, I never saw it anywhere - except on the install disc.

It's usually one big cat for each new major upgrade.

10.0 - Cheetah 
.1 Puma
.2 Jaguar
.3 Panther
.4 Tiger
.5 Leopard
.6 Snow Leopard
.7 Lion
.8 Mountain Lion.

Yeah, I love big cats. :P

Can you try the HTML5 versions? I know in the settings you can select to view YouTube videos in HTML5 browsers. I have noticed they run better than flash does in Chrome.
