I erased My Mojave system and few files on MACPRO 2013 to install Sierra from a bootable key
The MAVCPRIO came with SIeerra and as I got it I dowmloaded from Apple Store the full installer and using Apple suggesion I created a Terminal ways as suggeted in apple support to keep safe.
Testing the Key Sierra installer iit worked properly as everythinga wwas available fron the original apple sites.
Erased Mojave icking Option to inbstalolo Sierra in the the SSD grom nothe twe different Reecivery modesRecovery I see Highh Sierra, but the continue button doesnt di anything so I0'm stuck as from GHighSierra I could diowngraded to Sierra. In anycase the internbal SSD doesnt show.
Booting from a SIerra fully installed external drive to arrempt ussing Carbon Copy agaimn The SSD doesn't show up,
How tomake it appear? I erased all the APFS files from The reciovery option.
What to do?
