Catalyst in snow leopard

[samsc]

Something else to think about is that the rumor of Snow Leopard being entirely Cocoa. Right now, there are APIs and frameworks in the beta that are still using Carbon. Basically what this means is that there might be a need to entirely reconfigure applications running on the new system. Catalyst would most likely need some rewrite depending on how radically different the interface.

I can't speak for Richard here but from my own development observations, are that while Snow Leopard will "look the same" to end users, it will be radically different inside and Catalyst won't work quite as well (yet).

No- catalyst should work without any changes at all in my code.
and so should all previous versions of catalyst.

if it doesnt work apple has broken something that needs to be fixed.

a carbon/cocoa API divide is misunderstood by many people- and its not relevant.
