Some Keys not working after Sierra Update (Only for specific profile)

You probably have mouse keys turned on:

System Preferences > Accessibility > Mouse & Trackpad > unclick Enable Mouse Keys.

Hope this helps.

This solution worked for me. Darn I have had this problem for months, at last. Searched and searched.

This is the longest running problem I have had, I know it may seem a small thing but it's been such a headache having to rely on an external keyboard for so long.

So simple in the end, I know I may seem like an idiot but **** I am a happy one:)

If other keys don’t work

You may have accidentally set an option that changes how your keyboard operates.

• Choose Apple menu > System Preferences, click Accessibility, then click Keyboard. Make sure Slow Keys is turned off. If Slow Keys is on, you must hold down a key longer than usual before it’s recognized.

• Choose Apple menu > System Preferences, click Accessibility, then click Mouse & Trackpad. Make sure Mouse Keys is off. If Mouse Keys is on, pressing keys in the numeric keypad moves the pointer instead of entering numbers.

• Choose Apple menu > System Preferences, click Keyboard, then click Input Sources. Select “Show Input menu in menu bar.” Open the Input menu, then make sure the correct keyboard layout is selected.

  To see the keyboard layout, click Keyboard, then choose “Show viewers for keyboard, emoji, and symbols in menu bar.”

macOS Sierra: If keys on your keyboard don’t work
Thank you for using Apple Support Communities. Have a nice day.

Try safe mode if your Mac doesn't finish starting up - Apple Support
Take care.

Worked for me. Thanks.

I have the same problem here, and I can't log into Mac OS because my password's keys are not working. What can I do to solve this problem?

Hi, glad to know somebody talk about this problem. I have trouble logging in since the keyboard doesn't work. Moreover,

Moreover, there's no "apple" logo on the left which means I can't change any settings.

Thanks heaps!! After my toddler mashed my keypad, it wasn't working.. It was the Mouse keys were on 😀

Very happy and relieved here 😀

Choose Apple Menu > System Preferences > Accessibility > General > , Under Accessibility shortcuts uncheck Slow keys, Sticky keys, mouse keys. This worked for me.

Good Luck!

I had this issue after enabling mouse keys but according to Apple's support only number keys should not work.

Thanks a lot, i tried many other solutions, but none worked, then i tried yours and it worked well. Thanks

Go to System Preferences, then Accessibility. Click Mouse & Trackpad, look for Enable Mouse Keys, uncheck its box. Hopefully it will resolve your problem.
