Gone away a laptop with the wrong keyboard layout?

I gave a friend a Mac bookair. She hardly speaks any German and will soon be returning to Indonesia because she is a student

I only noticed now that I bought her the expensive laptop with a GERMAN Tatstaur! When she's back in Indonesia she can't do anything with the öäüß!

what have I done? What now!

Well in the best case, she knows her keyboard by heart, I still have an English one and I still know where each key is in German and you can buy a new keyboard or replace certain keys

Well, maybe your girlfriend in Indonesia can then use an external keyboard with the layout there. I suspect there are possibilities via USB (possibly with an adapter) or Bluetooth.

If she bothers herself so much about the keyboard, she will probably be able to buy an external keyboard with her desired layout. Such keyboards are available for very little money and are connected via BT.

Unless she sells the device anyway and gets something cheaper (I would do because I didn't want an Apple device, no matter how expensive it was), she will know what to do and in Indonesia she should get such keyboards thrown afterwards for Lau.

Check with your dealer what it costs to replace the caps. First select the desired language in "Language & Region" in the system settings, in "Keyboard" at the bottom tick "Keyboard… Show in menu bar", then select the alternative in "Language & Region" and click on the keyboard in the menu bar at the top Date) and there "Show keyboard overview". Take a screenshot of this, then select the original language again, including a screenshot. Now compare. There are several methods, but that got too far here.

I'm not sure which layout they use in Indonesia, but swapping would of course be the most obvious option.

With good laptops you can sometimes swap the entire keyboard, of course you would need a spare part and at Apple I'm not sure whether that is possible.

The other options would be to simply swap the keycaps, but the disadvantage of this option is that you can of course change the arrangement and shape of the keys. ANSI keyboards, for example, have a different Enter key. But there are also stickers for this kind of thing, but they break over time.

In principle, it doesn't matter what is written on the keys, you can choose a different layout on the software side. The only problem is if you can't type blindly or if a key is completely missing on the keyboard, e.g. The ANSI layout has one key less than the German, otherwise there are virtually all keys with different lettering and sometimes in slightly different positions.
