@emil Not sure if anybody is still monitoring this, but I'd rather not start a new topic with the same question.

I have quite a number of Flic 2s and I have lost track of what one if them does. Apparently it's already paired to something, but I do not know to what (hub or phone). Hence I do not know how to unpair it.

Before going own the battery route (I find it tricky to open and I'd rather not stick the button anywhere if I do not have to) I'd like to know what the alternative is.
I do not quite understand what "while you scan" means. I do not know if it's connected to hub or phone, how do I unpair it then? If I press it says it's paired.
It's probably very simple, but I do not know how to do it.

Thanks!

For anybody still looking for such a solution here's my contribution:

Mac Mini server 2010 running 10.13 + Hideez Smart USB Bluetooth-adapter works perfectly with Flic 2 (I use the button in universal mode to zoom and close windows since I use the mini as my media center).
It won't work with 10.12. The button pairs at first, but looses connection after a few seconds and does not execute any of the universal commands. 10.13 solved the problem!

Just make sure you follow these instructions: https://dongle.hideez.com/how-to-use-hideez-bluetooth-dongle-on-macos

Especially the terminal line so that it always uses the dongle and not the internal BT module.

Ver satisfied indeed!
