Installing Mac OS Mohave on NVMe card on Mac Pro (mid 2012)

Videocard not listed in the list; "Zotac GT 710, 2Go DDR3" Unusual attempt. Mojave install properly; disregard the previous "highSierra disk". Little tricky, but running right now.

"F ... ng hot" to try. Workin' on this for months; "HighSierra" never comes up. I did a try last night; putting my "Zotac GT 710 2 Go DDR3" in the box, and it fired up. Today, I removed the ATI card, wich block the installation of "Mojave". What's the result? "Mojave run on my Mac Pro (mid 2012).

Every attempt to install "HighSierra" on the NVMe was blasted.

There was an issue with High Sierra and nVME support. You had to run High Sierra 10.13.6 to get the firmware upgrade to make nVME cards Bootable. But that firmware could not be installed from an existing nVME card, because it was not bootable until you installed the firmware update.

The requirement is mentioned in this document, but readers went round and round with it on Mac Pro 2013 models and replacement internal drive installed BEFORE firmware update.
