How do you force AA with a Mac?
Supposedly there is an ATI panel to do this, but only for ATI cards, and only for PPC Macs as far as I know. You can find more info about that
here. If you don't have an ATI card, or have an Intel Mac, then perhaps
this is your only fallback. It's rather dumb as far as a proceedure goes, but it will do the job.
In any case, you are probably better off waiting for the game to support FSAA natively. It's not at all difficult to do, just not very high on the todo list yet. I'll get to it in another month or two though.
Forcing AA'ing with games that dont support it is dangerous. Forcing a Mac to do something it shouldnt be doing is even more dangerous.
That's just dumb on both counts. Forcing AA is not at all dangerous. At the most you'll just run out of video memory, or have the occasional rendering issue with some apps.
