Valve's Hammer Editor for Mac OS X

Someone made a Wineskin port of Hammer from the Source SDK for Mac. It runs pretty well and I can’t tell the difference between running it on a PC and running it on a Mac.

Has anyone made a port of vtfedit or so to mac?

Yes:

Neat, does this person by chance have a site I can direct people to?

Both ports can be found on porting team.
