this is literally a developers worst nightmare ... i experienced this one time when we released an android app. the auto updater broke. so we had to phone the customers to uninstall the app and install a new app. now this was with less than 1,000 users. i can only imagine how this would be like for company like Apple.

They control the entire OS. They'll have a lot more options to fix this.

Your development shouldn't depend on one PC. Code in git, DB in backups. You should be able to restore your dev state very quickly from scratch. You could even use Docker.
