Although the Mountain Heister Support answered within 24 hours, but was unfortunately useless. They ignored my questions (which combination has been used in contacts on the pin) and asked me but at Apple to ask if the MacBook is supported.
I would actually give this cable really not a bad rating, because it is to go with my headset G4ME One designed and otherwise makes a tidy impression. The sound quality was also higher than the then tried out USB sound cards. However, if you advertises that it is on Mac, and it does not work, unfortunately I have no other choice than other users with the same setup to warn.
