I have this problem that I'm not getting bootscreen og boot picker on my Mac Pro 5.1 (2010)
When I boot I have black screen for about 20 sec the the monitor gets signal and turn on with the Mac login screen.
When I'm in Mojave I see the last sec of the boot progress bar and the the Mac login screen.
I have everything up and running with Catalina and everything is working eg. hardware acc.
The system disk is on a NvMe disk, Mojave on a SSD in one of the trays. GPU is a Sapphire RX580 Nitro+ with a 32" 4K Eizo screen connected with DisplaPort - have tried both DP 1.1 and DP 1.2
I have also tried connect it with HDMI and also to a 27" non 4K monitor.
OpenCore is 0.6.6
Have attached my config.plist
