Hi,

Im having a quite of an issue while booting with my AMD graphic card. I was able to install macOS 10.14.5 and Clover bootloader successfully.

My system will boot and the card is recognised by the OS, but for some reason while booting the graphics card can't get graphics displayed on the display until the system has gone first to sleep mode. The screen just Flickrs and it seems to search signal. I'm using graphics cards DVI port. After that graphics are displayed properly and after that the OS runs like a dream.

Have any one encountered similar problems, and which kind of solutions are being used to fix the issue?

regards
Kozom

I manage to solve my problem, by lucky coincident! There's something with the DVI-port, which caused the problems. I was able to boot successfully with out any issues when the display is connected via graphic cards mini-DP port.
