Hello, I have inserted this card into a MacPro 5.1 (singleCore) with Mojave and it remains dark (yes, it is known that there is no boot screen). FileVault is also off. Does anyone have any idea what else this could be? It still has 2 additional disks with Raid1, but that should not interfere. Thanks for any hints.
