In mac, you can connect to in game voice and hear your teammates use it, but you yourself cannot speak through it. Heroes also does not seem to appear in system preferences as something I can give permissions to for microphone access. This was working about 2 years ago if I remember correctly, but lately I have not been able to give heroes of the storm Mic permissions as it simply does not show up. There is apparently away to by pass this with some technical know-how, but I am not that tech savvy and do not want to mess up my computer by playing around with security protocols on it I am unfamiliar with. If anyone has an answer or if this is some bug that needs to be fixed, please let me know, I would really appreciate it.
