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. +### Issues with dual boot setups + +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.
