Changing input source with Caps Lock key not working
It should be possible to change input source with the Caps Lock key on macOS Sierra,
and I have checked 'Toggle ABC input source with Caps Lock' in System Preferences > Keyboard > Input Source.
However, it doesn't work and Caps Lock still only works as Caps Lock.
I've tried rebooting, resetting keyboard shortcuts, disabling Siri, resetting NVRAM, resetting SMC but still not working.
I've been only using the default input source, and haven't installed and programs related to the keyboard or the input source.
Can anyone help?
Thanks in advance.
