Caps Lock (as input switcher) on MacOS about keyboards

[LovelyAlpaca]

KEY-DOWN - QMK: KC_CAPS Event key: CapsLock Code: CapsLock KeyCode: 20
KEY-DOWN - QMK: Event key: Unidentified Code: Unidentified KeyCode: 0
KEY-UP - QMK: KC_CAPS Event key: CapsLock Code: CapsLock KeyCode: 20 in 123.000ms

This is what happens when Caps Lock key is used as the input source switcher in MacOS.

I don't think that this is a VIA problem.
VIA is just a GUI for changing the keymap.

This is more likely an issue with the underlying firmware which is QMK.

Disabling NKRO does the job.

@stage-two you are saying that the only thing needed is to disable NKRO or also change the tap delay?

@yiancar just NKRO.
Tried it on: GMMK PRO, couple of Keychrons and others with Mac Mini 2018 and couple of Intel-based MBPs.
Same story everywhere: setting NKRO_ENABLE = no in qmk rules.mk fixes Caps Lock input source switching.

This issue seems to be unrelated to VIA itself.

Thank you for the info!

This works for me, awesome!
FYI in VIA you could set some key to 'Toogle NKRO' and press it to toggle it off, then you can unbind it and set to other keys you want.
