I will never trust Apple as long as I live. That's for many reasons over the years, but just as an example of why I hate them so much now...
I have just wiped a Macbook Pro ready to sell it. I made my own bootable USB installer for Catalina. I booted to recovery volume, then formatted the internal SSD, competely wiped clean
I then installed Catalina for the next owner. During the setup I decline all the crap, Siri, network setup etc. I actually ticked "this computer does not connect to the internet".
Catalina finished installing and loaded up into the fresh account. I then see it wants to install updates. How? It isn't on the internet?! YES IT IS. It has turned on WiFi and connected to my WiFi WITH a very secure password. Now I am thinking, how the F*CK does it know the password to my wifi? Where did it store that info if I formatted the internal drive? What if the new user drove to my house and sat outside, he could F*CKING connect to MY wifi?!
Someone blow up Apple, PLEASE!
