I have had 4 different versions of UE in the last 14 months (on my mac) and never been able to get ProRes. Or see my CamLink or Facetime in my mediaPlayer. I’m now up to 5.1 and still no joy… I tried using Parallels app to use windows. It instantly gave me ProRes and saw my facetime and Camlink camera. However, it will not render anything properly after the last update of V4.27.2. It is also buggy in the earlier versions. Over my 30 years in the business, this is the one software that has defeated me (whilst on a Mac).
