So for the last week I’ve had continued degradation of Bluetooth performance on multiple devices. My headphones (Sennheiser PXC 550’s) and my mouse (Logitech MX Master) have been in disconnecting/reconnecting loops… most notably the mouse. I’ve tried charging both; I’ve tried changing the keyboard batteries (random hope since also logitech); I’ve even tried using one without the other, and moving them out of the room from each other, thinking it could be too much interference… all with no success. Then I found a Youtube video of a guy with the exact same problem, and a comment with a solution. Granted I don’t know the EXACT cause of the issue, but at least I have a functional mouse and headset again.

The Solution: Hold [Shift] + [Option] when clicking on the bluetooth icon in the system tray. Choose the Debug sub-menu, then chose Reset.
