Remember, I'm doing a clean install. To speed up the setup, I want an inventory of all my installed apps and configurations. If you've installed `mas` using `brew`, you have a command-line interface to your App store installs. And `brew bundle dump —all —description —force` will write a list of everything you've installed from brew and the app store to `brewfile` in your home directory. Save that! Running brew bundle install will reinstall everything (you might want to edit the list first to avoid reinstalling stuff you don't want) But what about apps you installed by hand. There's no easy way to reinstall them, but at least you can get a complete list of everything you've installed with a simple terminal command `ls -la /Applications/ > Installed-Apps.txt` Now that you have a list of installed apps you might want to save configuration files. You'll have to do that manually for GUI apps, but in most cases, they store these files in Library/ApplicationSupport - remember there are two Library folders, the system-wide folder in the root directory, and the Library in your home directory. Make a copy of both and store them on an external drive. If you've moved your Home directory to a separate partition or drive your ~/Library will be preserved. So no need to worry about that. Just make a copy of the system-wide ApplicationSupport folder. CLI programs usually store their configurations as hidden files in your Home folder. These files usually begin with a dot. You can see them with the following command: `ls -ld *.` As you can see many of my dotfiles are really aliases to files stored in a folder called Sync. This is where Syncthing comes in handy Dotfiles often contain private information, like PGP private-keys and mail passwords that you wouldn't want to store on a public server. Instead I sync them to a shared folder available on all my systems. That way I always have access to dotfiles I want to use on all my machines, but I keep them away from prying eyes. I've written a little shell script to automatically alias them when setting up a new machine. Remember aliases?
