I have the MacBook Pro 2016, and I've been having a variety of bluetooth problems for awhile now.
I cant ever connect my Bose headphones to my MacBook. Usually, I connect it, and within 5 minutes it disconnects and I have to reset the bluetooth module, then it works. I have to reset the BT module every time I reconnect my headphones, which is a little excessive. Also sometimes in the middle of a song it just disconnects.
As well, today I put my laptop in my bag, and went to see it about 2 hours later, and the fan was running like crazy. No idea why it was overheating.
