BACKING UP There are many options for backing up your stuff, manually or automatically. As an example, Apple engineers were aware of the need for backups and that most people didn't backup. So Apple provides mechanisms to help users backup automatically: 1. iOS/iPadOS allows automatic backups to Apple's iCloud. 2. MacOS allows automatic Time Machine backups to an external drive as well as backups to the iCloud.

And if you believe in it, you're not only a sucker, you've been brainwashed into accepting your lot as a 2nd class digital citizen. The cloud is a lie because it convinces you of at least two Stockholm syndrome things: (1) you don't deserve to own or control your own data, and (2) security for your data does not matter.

DOWNLOADING AND RUNNING SOFTWARE IN THE TERMINAL Homebrew https://brew.sh https://en.wikipedia.org/wiki/Homebrew_(package_manager) Homebrew is a free and open-source software package management system that simplifies the installation of software on Apple's operating system, macOS, as well as Linux. The name is intended to suggest the idea of building software on the Mac depending on the user's taste. Originally written by Max Howell, the package manager has gained popularity in the Ruby on Rails community and earned praise for its extensibility. Homebrew has been recommended for its ease of use as well as its integration into the command line interface. Homebrew is a non-profit project member of the Software Freedom Conservancy, and is run entirely by unpaid volunteers.
