I replaced the Geforce GTX 980 by a Radeon Sapphire Pulse RX 580 in my MacPro 5,1. Sometimes, when I boot under High Sierra 10.13.6. the processing bar and the login window don't appear. The screen remains grey. I used screensharing with a second computer and there the login window from the MacPro appears, so I can reboot the MacPro from there. But it's annoying. Is there a solution to avoid the grey screen?
I uninstalled the NVidia and CUDA drivers. The problem doesn't occur under Mojave and never happened with the Geforce 980 when the webdriver was installed.
