Simply because I am the only dev who has a Mac and it works for me (although unplayably slow - the ATI drivers for OS X seem to suck performance-wise, even X.org's radeon driver is faster on this 9200). I certainly won't buy a Mac again, I am so disappointed by OS X.
If there is any Mac developer here who can try to help, please try fixing the problems (which I never had) and send in a patch. Thanks. Known problems to me are:
- Black screen (doesn't happen for me)
- No OS X 10.3 support (but that's stone age, and supporting it appears to break with universal binaries)
- Installation of patch is hard (won't fix, as the patch needs to still work for Linux and Windows)
- data directory not inside .app (won't fix, because otherwise both Nexuiz.app and Nexuiz-SDL.app would need their own copy of the data)
