getting a Bluetooth speaker to work is a must, thanks to the T2 leading to a crap audio experience in Windows 10 - sound glitching, plus the Spotify app just causes all sound to cut out. It might have options to turn off power saving try disabling that if possible:

Afterwards I was able to get my speaker to pair once again.ĭepending on which Mac you have, with older Macs you probably have a separate Bluetooth driver. Worse yet, when I click on Properties for the device, I get: The drivers for this device are not installed. The problem is that, in Windows 10 Device Manager, my Bluetooth USB Host Controller (found in 'Other Devices') shows that no drivers are installed. Removing all Bluetooth devices beforehand is important, as they magically pop back into Device Manager if you don't. The installation had been done using Apple's BootCamp software. Then Action > Scan for hardware changes, to readd Bluetooth hardware.

So the next step was to remove all Bluetooth devices in the Settings app, then go into Device Manager and remove all Bluetooth hardware.

Applies if you're on Mojaveīut that wasn't enough for me. Someone suggested via this reddit post to fully power down the Mac, wait a bit, then boot directly to Windows. So through trial and error on my 2018 Macbook Pro (with a T2 chip), and booted into Windows 10 with Boot Camp, I figured out a workaround to force my bluetooth speaker to not re-pair properly after a reboot.
