Option key stopped working
The option key on my MacBook Pro (Retina, 15-inch, Mid-2015; MacOS 10.12.6) just stopped working. In the first half of typing a sentence, it worked (on shift-option-hyphen). In the second half of the same sentence, it stopped working. Since then, it has not worked. Any combination of the option key and another key produces nothing. This is true in Word, Notes, TextEdit, Safari, and any application I try.
I've restarted the MacBook Pro. There's no change. The option key doesn't work.
I've connected an external keyboard. There's no change. The option key on the external keyboard doesn't work. So, apparently, it's not a hardware problem with the MBP keyboard.
Any suggestions? (Of course, I can take it to an Apple Store.)
