Mousepad replacement for Mac air 2019

The Touchpad is one of the easier repairs in this system. We don’t have any guides but the MacBook Air 13" Retina 2018 Teardown gives you a good idea whats involved. Now the bad news, the trackpad also has the keyboard key mapping so you need to get the trackpad for your keyboard as an example you have a US keyboard but you put in a UK touchpad it all assume the keyboard is a UK keyboard and will not offer all of the expected action/character you typed.

Basically you’ll need to go to an Apple Store or authorized service center so you get the correct one. If you are not able to get the correct trackpad for your keyboard.
