2012 13" MBA - Comma & Period Keys Nonfunctional

[MacDann]

I have a 2012 13" MBA that I am running the Sierra public betas on. After a recent update, my comma and period keys no longer work. I'm not sure if this is a result of the software updates or a hardware issue. Every other key works as expected, and there have been no physical changes or events such as spillage or drops to the MBA.

I find it odd that these two keys would suddenly stop working of their own accord.

Searches of the bug reports for Sierra public betas yield no issues of this type that I could find.

Any ideas/direction to try and resolve this would be appreciated.

Have you tried a PRAM & SMC reset?

Dang! You know, I feel stupid saying this now, but no, I have not.

It's been so long since I've had an issue of any kind with my Macs I forgot the cardinal rules of troubleshooting.

Thank you! I'll report back later today when I get a chance to do this.

Zapped the PRAM and did an SMC reset - no joy

roll back the beta. you likely have a bad kext.

Thanks! That's next.

Surprisingly, when I first reset the PRAM and SMC, it worked. Then I let it update (bad idea) and now it doesn't. And that's after another PRAM and SMC reset.

Fortunately, I don't use this machine for much so I can easily restore it and revert back to a stable OS. I'll do that tonight and report back.

Well, I got around to installing a production version of Sierra on the machine today. No joy. Still no comma or period.

Any other ideas/suggestions?
