Hi Greg,
This is the first email that I’ve sent from this MacBook Pro 15” 2018 Intel which I bought 2 weeks ago. Early today I succeeded in creating a bootable installer of macOS Mojave within one of two volumes within the GUID - HFS+ structure of a Samsung
T7 External SSD, and then used it to install Mojave 10.14.6 within a new prebuilt GUID - APFS volume named, “macOS Mojave”, ’next-to’ the "mac” volume with Catalina 10.15.?6 and the volume “Mac -data" on the Internal SSD.
So. Mojave is up and running natively, next find the Supercard stuff (smile,hopefully)…
Mojave is the Correct Color (green) on the graphic of Internal SSD Container of volumes.
(See attached image)
That’s appropriate
Little by slow,
-Dan
