macpro 4.1

Sorry if this has been discussed. Recently acquired a 2009 MP 4,1>5,1 with RX 580. I can see the os image from the bootcamp viewer, but it wont boot into macos Catalina. It will just re boot into windows. I may have deleted the macos boot from the image, but not sure. Holding option brings...

If this has been addressed before I apologize - I couldn't find it. I have a 4,1 w/ firmware update to 5,1. Running Sierra and Maverick. I did do the 1.4 update to be able to run nvme bootable as I was running High Sierra with an Sapphire Pulse RX580 but moved that setup to another MacPro...

Hopefully someone can shed light on this situation... I have a MacPro 4,1 that’s been upgraded to a 5,1 and currently running a 6-core 3.46 in Mojave with boot rom 138.0.0.0.0 I recently got a ridiculous deal on a MacPro 2009 upgraded from 4,1 to 5,1 running a 12 core 3.46 in OS X 10.13.6...

Hi all I installed Mojave on my 4.1 without reading the full instructions. DOH! It works reasonably well but video is stuttering in Quicktime and doesn'tplay at all in VLC, it jus goes nuts and I have to for close the app. I was asked if I had graphics acceleration enabled and the truth is I...
