This Bluetooth is still driving me up the wall. Its clearly an OS X problem. I can pair my Android phone to either my H9 Max or Boss GT1000 using the appropriate app, but can only pair the H9 with the Macbook Pro if I literally sit the H9 on top of the Macbook! I don’t ever recall having any problems until I put High Sierra on. I would gladly go back to 10.12 (or even 10.11) if I could get everything back to normal. I expect Apple will just say “Oh, its your music hardware at fault” or “Updating to the latest High Sierra will fix it”. No it pigging won’t!!
