EQ for Mac is a separate game, with a separate client. That means that our servers are not set up to handle that client (OpCodes, features, etc). It could be set up, but it would likely require a separate community (eqmacemulator.net anyone?) to dig through and build it. Nothing is impossible, but I doubt that the necessary talent pool is going to be inclined to coordinate an effort like that.
I played EQ for Mac briefly before coming back to EQEmu (trying to recapture the old EQ memories), and would be game for working on a project to convert the server to work with the EQMac client, but I'm hardly qualified to do much on that front.
