Um, Enders does have a mac client, I have it. It is lacking a few things, but has the good ones like night vision, xray, and a bigger screen. I would give you the link but Im not sure where to find it or how to post it. Hopefully someone the does will read this and post it for you. If you look hard enough it is in the forums. Good luck.
(Still wondering if there was an update for mac enders after w6 started...)
