attack of the bteam can't play attack of the bteam on tekkit launcher

[_jd_]

For some reason, I can not play attack of the bteam.Every time i press the "Play" button it starts attack of the bteam , then stops and goes back to the technic launcher.It only happens to this one modpack.

By the way , not sure if this is the reason , but im on a iMac
