Maybe this is old news but I've got an older Mac system (Corei7 5k iMac from 2015).
I just got my new iPhone 12 Pro Max two days ago.
Turns out that if you plug in the phone to a standard lightning cable to a USB-3 port the iMac doesn't see the phone apparently.
I've tried it with my iMac and a Windows 10 laptop.
But, if you use a USB-3 to USB-C adapter to the cable that comes with the phone it charges and transfers data fine.
And if I connect the USB-C to lightning cable to the Windows PC the phone charges and also data transfers.
I suppose this is old news or I should have assumed it but I could see a lot of people bring irritated by this.
