On modern versions of macOS, you simply can’t power on your computer, launch a text editor or eBook reader, and write or read, without a log of your activity being transmitted and stored; Current version of the macOS, the OS sends to Apple a hash (unique identifier) of each and every program you run, when you run it.
This data amounts to a tremendous trove of data about your life and habits, and allows someone possessing all of it to identify your movement and activity patterns. For some people, this can even pose a physical danger to them.
You have to make an exclusive choice: you can have a fast and efficient machine, or you can have a private one.
