A MacBook Pro keyboard conversion kit is a set of replacement keycaps designed to change your MacBook’s keyboard layout from one language or regional format to another — for example, converting a German QWERTZ layout to a UK QWERTY layout, or changing from French (AZERTY) to US English.

Rather than replacing the entire keyboard assembly (which is expensive and time-consuming), a conversion kit allows you to simply swap the keycaps themselves. This is a much quicker, more affordable, and fully reversible solution. Once installed, your keyboard will visually match your preferred layout, and by updating your macOS input source settings, your keys will also type the correct characters.
