What is the use case for this feature? I have never needed or wanted to see what is on my phone on my computer. Do people leave their phones in the other room and instead of getting up to get it they lazily can now log in from 15 feet away? This is another example of Apple's phase of "re-arranging the deck chairs on the Titanic" when it comes to Mac OS, which has been going on for several versions now. They create apps (Freeform) which no one needs and features like this which benefit very few. How about fixing HomeKit? Or getting Siri to actually work? Or updating Apple Music into something modern (I am looking at you, Playlists on the nav that are impossible to organize). I have been using Apple products since 1983, and I believe we have reached the reductio ad absurdum portion of our program. It's gotten bad enough that I have considered buying a Windows laptop. And I hate the f---ing NOTCH.
