Pushed a small commit that excludes binding the right control key under macOS.

I suppose prior versions just silently continued, but this warning makes sense because macOS systems don't have a right control key:

Tentatively closing.

@kcgen This is still happening for me on both the Mac mini (Catalina) and the Macbook Pro (Big Sur).

Have tried to generate a new keymapper file and see if that problem is still repeated there? File is mapper-v2.map. Remember to backup old one and then remove it.

[Burrito78]

There is no .map file on my system. Maybe i would need to map something first for it to exist?

[Grounded0]

If you don't have a mapper file in ~/Library/Preferences/DOSBox then you're running default keymap and yet the warning still pops up.

[Grounded0]

Happens on latest main with default keymap.
