I made my own EFI according to the opencore guide, using opencore 0.68, all drivers and kexts are downloaded from the latest, but after booting and selecting system recovery, after running the code, the monitor lost the signal, I don't know if there is something wrong with my config.list settings, I change the model, such as iMac19,1; iMac19,2; Macmini8,1 and other models, the situation is the same, I suspect if it is the interface of the monitor, but I have no more monitors to test.
My monitor only has three interfaces, DVI, HDMI and VGA, while the computer has two DP ports and one VGA port
Because I know macos does not seem to support VGA anymore, I used a DP-HDMI adapter to plug into the monitor
However, after I downloaded this file from olarila to install https://www.mediafire.com/file/ws7fpljza84ueia/Olarila+BigSur+11.2.raw/file
The signal is output from VGA, but the DP port signal is disconnected
I'm not sure why, but I'm glad I was able to install it successfully.
Today I used opencore0.68 to make a brand new EFI folder to boot the system made by olarila, but as I said before, the screen went black and it seems that both DP and VGA lost their output signals.
I would like to know what the cause is.
Also, after I changed the model to iMac19,1, I used istat menu to check the CPU usage and was able to recognize 6 cores, but the GPU never showed the temperature, just a " - " symbol, I don't know if the cores were not driven successfully, Then I tried to output a video with finalcutpro and found that only 6 CPU cores were involved, while the GPU did not respond. At the same time, the computer became very laggy. I tested it with MacX Video Converter Pro, and it looks like the computer has hardware encoding acceleration enabled, and HEVC is also shown to be active.
The second point is that there is a bug in sleep, when the computer is woken up, the monitor display resolution will change and the display screen becomes very narrow, I tried several tools to modify and fix the resolution, still not working.
The above is what I encountered, I hope I have elaborated the problem clearly. Attached is the file I got with runme.app and the debug file when I made the EFI boot system with 0.68opencore, hopefully it will help me find the cause.
I'm grateful for your help! MaLd0n?
