 If you want to test bluetooth output on your keyboard and are powering it through the USB connection rather than a battery, you will be able to pair with a host device but may not see keystrokes sent. In this case you need to use the [output selection behavior](../behaviors/outputs.md) to prefer sending keystrokes over bluetooth rather than USB. This might be necessary even if you are not powering from a device capable of receiving USB inputs, such as a USB charger.

+Since ZMK associates pairing/bond keys with hardware addresses of hosts, you cannot pair to two different operating systems in a dual boot system at the same time.
+While you can find [documented workarounds](https://wiki.archlinux.org/title/bluetooth#Dual_boot_pairing) that involve copying pairing keys across operating systems and use both OS with a single profile, they can be fairly involved and should be followed with caution.

 ### macOS Connected But Not Working
 
 If you attempt to pair a ZMK keyboard from macOS in a way that causes a bonding issue, macOS may report the keyboard as connected, but fail to actually work. If this occurs:
