I purchased an OWC Aura Pro x2 for my 19,2 2019 iMac. I was able to physically install it but had a hard time installing OS Sequoia. I eventually got it but the Mac will not “restart” and find the ssd to boot to. (Flashing folder with question mark). I can shut down and boot just fine, but cannot restart. So the iMac cannot complete system updates or Migration Assistant without the ability to restart.
Any ideas?
OWC support is now telling me the Aura Pro x2 is not compatible with 19,2 iMacs. On their site the PCIe 3.1 says it’s compatible but 4.0 is not.
