Dude, come up with a new Mac OS version already, please!
It's on it's way....the last 2 versions had issues with mac and some parameters were not being set within the client. That seems to be fixed now. Crypotocoderz will release the MacOS version soon, but I believe he is going to push a fix to the syncing past block 5 on a fresh install problem first. Once that is released, a new MacOS client will be built and released alongside or shortly after the Windows one.
