First time poster here. My XDR display all of a sudden stopped working with my Mac Pro when I woke up a few nights ago, after what I assume was a firmware update to the XDR and/or an update to the Mac Pro that occurred the prior night.
Here‘s my setup: 2019 Mac Pro, 5700X graphics card, nano-textured XDR, with 25m Corning thunderbolt 3 usb-c cable connecting the Mac Pro in my server closet to my XDR on my home office desk. Up until a few days ago, this setup had been working perfectly for me for the prior six months (including after I’d upgraded to Big Sur).
But as of a few days ago, I just get a blank black screen on the XDR when I turn the Mac Pro on and the XDR. Nothing happens at all on the XDR when the Mac Pro is turned on.
I thought maybe something had happened to the Corning cable, so I tested it by plugging the same cable into my MBP instead of my Mac Pro, and the XDR worked perfectly when connected to the MBP using the same Corning 25m cable.
Then I moved my Mac Pro next to the XDR and connected it to the XDR using the short 2m Apple thunderbolt 3 cable that came with the XDR, and the XDR worked perfectly with this cable connected to the Mac Pro.
So I think whatever update was installed on my XDR and/or Mac Pro a few nights ago has caused my XDR to stop working with my Mac Pro when they’re connected via the 25m Corning cable (that I spent like $600 on).
Any ideas on why this is happening and how I can fix it so I can continue using the Corning cable with my XDR/Mac Pro setup? Any assistance anyone can provide would be greatly appreciated!
