Hello, ask for an advice, please. i have a MacBook Pro (Retina, 15', Mitte 2014) with dual Graphikcards, NVIDIA GeForce GT 750M 2 GB and the less power one: Intel Iris Pro 1536 MB i hae read: macOS Mojave requires a graphics card that supports Apple's graphics framework Metal, but until updated web drivers are released, many Nvidia graphics cards are incompatible with the operating system. In the meantime, some users have downgraded back to macOS High Sierra. Until now is no driver for 10.4. Is it right or? is it better when I like use the Nvidia to downgrade to 10.3?
