Can you check the status of the keyboard that is attached to your Mac as well?
I have tested N+S 0R000 on both PC and Mac and output is as expected. This is directly from my Twiddler:
Version = 0.13u
I think, maybe, Caps could be toggled on the regular keyboard attached to your mac to give you this:
vERSION = 0.13U
Or something could be resting on your regular keyboard's Shift key to give you this:
Version = 0>13u
The mixed caps in "VeRSIOn" is perplexing which leads me to think something is touching an intermittently engaging the regular keyboard's shift key.
