This version does not have the two folders for upgrade on or upgrade off so will it work as described in your video? If not where do I download the the exact version of the apps you used in the video. I am trying to upgrade a MAC Pro 5,1 boot rom 144 with generic RX580 8GB video card fro Mojave to Catalina Thanks for your input I forgot to mention my MAc Pro is early 2009 probably 4,1 upgraded to 5,1 and 12 core
