Sooooo I found my original Mac Pro graphics card: ATI Radeon HD 2600 XT that came with my Mac Pro. I put it in. I attempted the update again. It didn't install the Helper to update the firmware. I am not an expert but from looking at the Activity Monitor, it looks like it is deleted right after it is added. I know a properly flashed GTX 680 is supposed to allow the firmware update but I have not done an EFI flashing of a graphics card and don't want to brick the GTX 680.
Here is the root of my frustration, I was able to use tools to take my old MP 3,1 to High Sierra without all this firmware update problem. Is there something wrong with how this MP 4,1 was updated to 5,1 that is the root problem? Everything in this forum said any original MP graphics card should allow the firmware update. Yet, it seems no matter what card is installed, the firmware update will not happen. I am attaching screen shots of what I am using and the Activity Monitor.
I know I am being a pain in the rear but I desperately need a more powerful machine (the 5,1) since the 3,1 is increasingly unstable and fear I have been tricked out of what the 5,1 cost.
Thanks in advance
