So, just curious the mac exporter doesn't work? I like get a file with no extension

That file is a mac executable.
The same thing applies to linux executables, no file extension

Yeah, both linux and mac don't use extensions (instead they use the file's execute bit). The thing is not all gEs seem to be able to export to mac normally. I believe unless you are using a version built from the source, you most likely can't export to mac without special app packaging.

Is there a tutorial on that? I'm getting errors compiling from source even though I know I have the dependencies

Well... no there aren't any tutorials. There are instructions, but I guess you've been following that. I've only built it on Linux though (with quite a struggle at times), which I believe you don't use?
