is it really that hard to automate things on macos? I would have thought you could put most of the install instructions for everything you listed into a bash script? is macos locked down in some way? why is logging into things an issue if you have a password manager to auto fill things? on linux I just make a backup of the firefox folder so I don't have to reinstall the extensions on my new computer. all the settings files I want to keep are kept in syncthing folder then i have a bash script to create softlinks where those settings are supposed to be. doing all that manually every 3 years would be my idea of "really, really hard". with a script you just add the instructions once and then you can keep reusing it without any effort
