After updating my Macbook Air's OS to Sierra, I can't hold down a key to make variations of that key with accent marks appear. I've tried messing with my keyboard settings in System Preferences, but I can't figure it out.
Here's an image of what I mean:

Are you holding down the key long enough? Is this happening everywhere or just in certain applications?
Try setting up another admin user account to see if the same problem continues. Please post back on whether or not this worked. Also try the Safe Mode. Please post back on whether or not this worked.

If it works in the Safe Mode, try running this program when booted normally and then copy and paste the output in a reply. The program was created by Etresoft, a frequent contributor. Please use copy and paste as screen shots can be hard to read. Click “Share Report” button in the toolbar, select “Copy to Clipboard” and then paste into a reply.

I'm sure I'm holding the key long enough, this issue happens everytime I'm typing anywhere. It's not a serious problem, though. But now I'm wondering why would I have to go through so many hoops (logging in as another user or safe mode) to get something so simple that my mac air used to do by default, and my mac pro still does?
The other admin account and the Safe mode are tests to see if it is isolated to your account and/or possibly caused by installed 3rd party software. They are just test, not a guaranteed fix.
