I updated my MacBook Pro to Sierra 10.12.1 a couple of days ago. Since the update I can no longer pair with my Tacx Neo. It doesn’t seem to work through the build-in bluetooth on my MacBook Pro, or through my iPhone. Prior to the update it was working fine.
I was able to pair with Tacx app on my phone and verify that I have the latest firmware. I also erased all bluetooth devices and reset the bluetooth on my computer using the debug menu to no avail.
I have also been reading about issues on the Kickr after update. It sounds like Apple changed something Bluetooth related in the latest Sierra update.
