On November 17, 2021, Apple announced its own self-service repair program. This is designed specifically around the right-to-repair movement, a response to so many demands out there in the wild that owners of iPhones and iPads and Macs (and other devices) be allowed to repair their own devices without voiding any warranties. It's a way of thinking Apple hasn't subscribed to for quite some time, but it finally came around.
Apple will publish self-service repair manuals on its support site
