It's nice that I can mirror my iPhone onto my Macbook using a simple lighting to USB-whatever cable, then open Quicktime but what about the inverse of this? I want to simply record my mac's screen booting up into recovery, or record it in places where you usually wouldn't be able to open up Quicktime and record your entire screen.
Do I need to use an HDMI cable from my mac going into an external monitor, then record the monitor or can I use a dongle and trick my mac into sending HDMI input to my phone? Simply put, it's like recording the screen of a virtual machine.
I have a Macbook18,3
running macOS 12.1
and an iPhone 11 running iOS 15.1. If you happen to bring up third party apps, try and keep it free
