I haven’t been able to use my Apple Cinema Display because the cable didn’t work and it was very difficult to get hold of a new one.
Finally I found one on Ebay and was able to buy it for 30 bucks (and then an additional $60 in shipping 🤦♂️).
Changing the cable was not a two minute task. Had to take out most of the components.
But now it’s working and I’m happy.
