    Will apple ever fix this?

    I usually have 3 things connected to my MBP (I have two 2012s, 13 and 15 happens to both), a sound bar, magic mouse (v1) and the iphone itself trough LE for something called 'mac id' that allows me to unlock by proximity or touch id, handoff and stuff.

    anyway... it usually works fine but sometimes the audio starts to cut out. when I see that happening I open the bluetooth explorer and check the AFH maps, they are almost completely red, with like 7-8 green squares only. that in theory indicates the spectrum is completely dirty, which is not true as I use 5ghz wifi on the MBP and the only 2.4 wifi with significant presence is my router at channel 13 which is basically idle.

    if I let it going on with the stuttery audio, something eventually breaks/crashes (all bt devices disconnect and reconnect and I see a ton of stuff in dmesg) and suddenly the AFH is green again, with a few reds here and there as expected. audio works fine again for a while, then eventually the issue repeats.

    really annoying. ideas on how to diagnose this better?

    I used a bluetooth connection to my speakers to watch Game of Thrones today and after about half an hour the audio cut out, my trackpad and keyboard stopped working and the BT-menubar-menu froze along with System Preferences.

    From what I've heard - but it's never a full explanation - it has something to do with a low amount of cache available to bluetooth, or something. It just can't seem to handle both audio and other peripherals at the same time? Is this supposed to be the future? Apple? Anyone?
