Right now I'm using wine (from http://winebottler.kronenberg.org
) to run windows tools. I have a bash script in my maps directory that invokes qbsp like this:
/Applications/Wine.app/Contents/Resources/bin/wine ~/quake/bjptools_xt/txqbsp_xt.exe jam_ericw.map
Seems to work fine.
I'd recommend against using native mac tools (or anything but 32-bit windows tools) for the moment, because it's possible you'll run in to this bug, which will cause corrupted lightmaps in some places: https://sourceforge.net/p/quakespasm/patches/15/
The patch lightmap2.diff should be applied to light tools, but I haven't had a chance to report it to tools authors with a proper test case yet.
