But does anyone care about MacOS? ;)

I mean, I know Mac has had some great games (eg. I spent so much time on school Macs playing that Bolo tank game) ... but they have probably <1% of the number of games Windows has. I'd expect a simiilar percentage of devs to be interested in Mace (or whatever you call Mac Wine).

Not sure what you mean. The number of Mac games isn't relevant to a subthread about a project to increase performance when Windows games on Mac.
