Unable to switch to Russian keyboard layout
I'm working on a Macbook Air (11 inch, early 2014). Recently upgraded to High Sierra 10.13.2. I'm now unable to switch to the Russian keyboard layout to enter text. The keyboard layout indicator shows "Russian" but when I type, English characters appear on the screen.
Here's a video that shows the problem: MacOS High Sierra keyboard layout bug - YouTube
The only layout I can change to is Japanese (this laptop was bought in Japan, and has a Japanese physical key layout).
Things I've already tried:
- Layouts other than Russian (e.g. Ukrainian, German) - they also do not work.
- Creating a new user: the problem is still there
- Rebooting
- Resetting the SMC
Any ideas?
