Question marked as
macOS Mojave - Technical Specifications
The graphics cards offered by Apple in Mac Pro (Mid 2010) and Mac Pro (Mid 2012) don't have GPUs that support Metal, so these systems require upgraded graphics cards in order to install macOS Mojave.
Before you upgrade to macOS Mojave on these Mac Pro models, you need to update to macOS High Sierra 10.13.6 and then make sure that your graphics card is compatible. You also need to turn off FileVault.
