This is to solve an issue where you use a non-apple european keyboard with the US keyboard layout in macOS where the Tilde key is in the wrong place.
This is the process for the Logitec MX Keys Mini
- Connect the keyboard (bluetooth)
- Make sure the keyboard is in PC mode (hold fn + p for 3 seconds)
- Go through the keyboard wizard and at the end select the European ISO... layout
- Switch the keyboard to Mac mode (hold fn + o for 3 seconds)
- Tilde should work
If this doesn't work:
- delete /Library/Preferences/com.apple.keyboardtype.plist
- reboot
- try above again
I had to do this again with the MX Keys S Plus today, and the same instructions worked out fine. It's like the Nordic keys one which I use in US layout. When I went through the Wizard it wasn't recognized as European ISO, but it was the only one with ISO in the name. "~" worked fine once I switched it back to Mac mode.
I mentioned the Wizard, because when it seems when you connect these Logitech keyboards to macOS by adding them as a Bluetooth device, they always bring up a keyboard Wizard (says something about not being able to identifiy which layout the keyboard is in etc).
Also I guess I should mention that I've never actually tried to buy the "Mac version" of these keyboards even though I see that is an option. Things might just work then, but these are the Cross-platform editions I've tested with where you have both key's printed on the actual keyboard.
