Black Screen after install Sierra 10.12.2

[romantosh]

I am trying to install Sierra on my PC after an upgrade to MSI Radeon RX 460 4GB. Before, i had on my PC El Captain and graphics card HD5750, and everything worked, i also tried to load El Captain on my RX 460 and it works. On Sierra it shows a black screen after install. I am using a Clover and FakeSMC.kext. System definition on El Captain was Mac Pro 3,1 (Early 2008). Maybe someone knows how to make it boot?

Welcome to the forums romantosh,
Black screen is a common problem using the newer AMD GPU's. Several threads about it in the graphics forums. You may want to take a look there, here is a link to AMD graphics testing. It is a long thread but the AMD 4XX cards of all varieties are being tested there. macOS Sierra PB: Need testers for new AMD Radeon drivers! There should be enough information there to get you up and running(workarounds) and other users will offer a helping hand.
