Mojave

[MikeEH]

According to Apple list of approved computers mine is. It is a macbook pro 2014 15" os Sierra. Attempted install repeatedly gave the following error.

macOS cannot be installed on this computer. (com.apple.diskmanagement.error -69854)

I have paid out $100 in support with the same result. I believe that macOS Mojave is faulty. Anybody have a fix?
