How to stop FN key changing my keyboard layout (macOS Big Sur)? I've got my new MacBook Air m1 very recently. I changed default behaviour of F-keys to normal F1, F2, etc. So in order to activate 'media' keys like volume up/down I need to press Fn+F-key. Now, what I've realised is that pressing Fn with F1, F2, etc sometimes (50/50 chance) changes the keyboard layout as well! God, it is so annoying. It shouldn't be so 100%. I think that's just a bug. So, how can I disable Fn for changing my keyboard layout?
This new feature of MacOS Big Sur can be turned off by unchecking a box in System Preferences &gt; Keyboard.
