HC no it wasn't. I used the original mac card when I did the first boot to 5.1 Not sure what happened to the old graphics card HC.
Thanks james for that tip, yes, the OS drive options appear.
Again, OS 10/12 claims when it finishes the upgrade that the drive is not worthy.
Still baffled. As mentioned I have two SSDs and OS allows me to load to the crucial then fails.
Possibly HC you know of a 2TB SSD that IS definitely compatible?
