Title says it all. My Mac Pro 3,1 has some weird issue with not being able to recognize any SATA drives. I have no idea why, but it only sees NVMe drives in the PCIe slots. Anyways, when I go to the startup manager, it’s literally blank. It’ll see OS X installers, but the hard drive doesn’t show up. Weird enough, it says that the NVMe is “Internal”, yet it shows the yellow external drive icon on Desktop. Does anyone know how to get the drive on the boot menu? It’s an old OWC card and I installed all of the drivers. On OS X Yosemite 10.10.5.
