I think he was wondering if there was ever going to be mIRC compiled into something compatible with mac's. In that case it's no. If you want to run mIRC.exe on a mac you can get a crossover program. Or buy Mac OSX. Enjoy!
I'm sure he would of mentioned or rather asked the exact question if there was going to be a MAC version. However good call though unless he posts again about it I doubt we both will never know

.
I just figured since the Subject/Question was "is mirc able to run on macs?" and using
Crossover that the answer to the exact question is yes. Crossover allows Windows programs to be installed on MAC intel OSX computers. Not just running an .exe, but actually install them

. Quite nice if you ask me.
