Answer to "Keyboard Intermittently Non Responsive - Top row of Qwerty only"I had issues with 789YUIHJKM or more. The issue was when I pressed these letters it moves the mouse point. I tried to clean it but it didn’t work. But somehow I went to setting/accessibility/touch/assistivetouch/mouse keys and then turn off the (use primary keyboard). Now it goes back to normal. Just in case if someone have the same issues. Magic keyboard. Thank you.
