I have been trying to get AAC to work over Bluetooth between my Tesla Model S (mid-2013, firmware v8.1 2018.16) and my MacBook Pro (macOS High Sierra 10.13.4; hardware is mid-2014). I followed the instructions on MacRumors to enable AAC (and aptX, which is not supported anyway), but the Bluetooth drop-down menu indicates that the active codec is still SBC. I tried playing music through VLC, iTunes, and regular system sounds. Have other people experienced this? Anything that I am doing that is wrong? While I would assume that my iPhone 8 running iOS 11.2.6 is streaming AAC, I have no way to verify that for sure.
