Not at the moment but we'll get a new compile shortly.
Just a heads-up, in case you aren't aware, the Mac version only supports hosting games and compiling from the command-line. It does not support playing games (for that, you'll need to set up a virtual Windows OS)
Thats what I want a better Mac version
When will byond make a Mac Version to play?
