They know when you open Premiere over at a friend's house on their Wi-Fi, and they know when you open Tor Browser in a hotel on a trip to another city. This means that Apple knows when you're at home. An IP address allows for coarse, city-level and ISP-level geolocation, and allows for a table that has the following headings: Date, Time, Computer, ISP, City, State, Application Hash Apple (or anyone else) can, of course, calculate these hashes for common programs: everything in the App Store, the Creative Cloud, Tor Browser, cracking or reverse engineering tools, whatever. Because it does this using the internet, the server sees your IP, of course, and knows what time the request came in. Lots of people didn't realize this, because it's silent and invisible and it fails instantly and gracefully when you're offline, but today the server got really slow and it didn't hit the fail-fast code path, and everyone's apps failed to open if they were connected to the internet. It turns out that in the 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. Security researcher Jeffrey Paul, writes in a blog post: 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.
