Don't worry you won't regret this decision at all Nope I don't think it has been tested on Mac yet... (EDIT: I recomment you to just explore the patch just for the moment because if you start a career it will be invalidated in the next version which is coming soon in the next days)
Next version in the upcoming days guys (new grunts exclusively for Djokovic and Murray, speed of courts modified, more outfit added to players for different moment of season: arrival of Indian Wells, Miami, Madrid, Roland garros outfits separately, playersatp.ini slightly modified ex: added more years to Federer, Hewitt ect.., added exhibition of Abu Dhabi!!!
