Well ... Catalyst works...
On the surface - there are no visual glitches ( apple fixed bugs i reported several months ago )
Since then i haven't seen any specific Leopard problems-
But as usual beneath the surface there are an awful lot of changes in the OS that might affect what we do-
So I have to urge great caution.
But as anyone buying a new mac knows - from Oct 26th - they wont have any choice in the matter.
Performance? I dont know - a little slower than 10.4.x - though not much.
Developers only got access to the release builds yesterday. The same day are everyone else - which is crazy...
So there isnt much time to have tested anything...
