Hi all,

I am using an external keyboard (PERIBOARD-612), which is compatible with Mac OS. The key mapping works fine except when the shift key is pressed. When the shift key is pressed, the command key and option key are swapped.

I would refer you to the third party developer for your external keyboard issues continue or try a different keyboard to compare your results.

see if there is anything here:
