better now? sorry as i said its hard for me to put this clearly since i really can'T make logic of any of it anymore
Nice, this looks like a capture from your own cMP. So, it's proved can work on cMP, correct?View attachment 898326
You can try this driver here to get this interface at boot:
GitHub - n-d-k/NdkBootPicker: External GUI boot picker for Official OpenCore bootloader
External GUI boot picker for Official OpenCore bootloader - n-d-k/NdkBootPickergithub.com
Yes. F10 makes the screen capture. Space bar shows auxiliaries. The newest Shell.efi does not work, but I don't think it is related to this driver, but only to OC itself. Can you please test the newest OC with the Shell.efi? if it does not work I will open an issue.
My recommendation is to keep it simple and use TextEdit. You can also use Xcode, but recent versions have a bug that affect data fields.
I use the OpenCore Configurator. There are warnings not to use it, but it works nicely for me.
OpenCore Configurator | The Original | mackie100 projects
OpenCore Configurator like as Clover Configurator will help you create custom configuration files for the OpenCore EFI bootloader via a streamlined graphical interface.

I have since discovered propertree, which will reload/remake the config file based on your EFI directory! Its pretty nice and its what the Vanilla OpenCore guides recommend using. You can use it on a mac or pc:
GitHub - corpnewt/ProperTree: Cross platform GUI plist editor written in python.
Cross platform GUI plist editor written in python. - corpnewt/ProperTree

I would NOT recommend using a regular text editor (including TextEdit). Its way to easy to break the config accidentally if you are doing more than just changing an existing value.
I played a little with open core and it worked for me with my GPUs with Bootscreen, I have seen the OS Chooser.
Now I want to do some tests with no-mac-bootscreen-but-uefi GPUs.
Excuse me for my ignorance
but I cannot get a boot screen with the settings of post 1 on some of my old UEFI GPUs like GT640 and Quadro K600.
I checked the Firmware and for example my K600 should have UEFI support
also I fired up nvflash and it gave me info:
UEFI Version 0x10015 (Oct 26 2012)
UEFI Signers Microsoft 2011
is that UEFI GOP or am I wrong ?
As an all time Mac User I have no clue about this UEFI GOP stuff.
I know that those GPUs are weak, but at least they are silent and affordable Kepler cards.

This happens when you are spoofing the iMacPro board for hwaccel... you need to remove that.
For others have the same problem.
I haven't test it yet. My cMP was doing something last night. I would like to confirm that 963KB version is the one that you want to test, and doesn't work.
Yes the latest OC compiles Shell.efi inside the folder automatically. Unfortunately it stopped working for me. I am using older version attached in previous post which still works. Also if I enter and exit shell and enter shell again it freezes even with this version and I have to reboot.
Activate AMD hardware acceleration
I created a new "easy to install package" as per many requested (based on the official OpenCore). [The attached package updated to 1.0.0] For those who only need HWAccel, post #594 has everything you need. This new package mainly offer HWAccel + boot screen. Also, this package should work in...

Strange, I just tried that 963KB version, not even show up in the boot picker. Of course, it's inside the Tools folder, with the latest OC 0.5.7 beta, and with the following code in the config plist.
Code:
<dict>
<key>Arguments</key>
<string></string>
<key>Auxiliary</key>
<false/>
<key>Comment</key>
<string>Not signed for security reasons</string>
<key>Enabled</key>
<true/>
<key>Name</key>
<string>UEFI Shell</string>
<key>Path</key>
<string>Shell.efi</string>
</dict>I just try again with NdkBootPicker. The UEFI Shell shows up in picker, but black screen / hang after I select it.
That's with the RELEASE version.
Same results as mine. The one attached works only the first time.
Still no luck updating to the latest beta. It is no longer asking to upgrade the firmware as I removed the board id injection. But I found this:

As far as Shell.efi see this comment

This probably doesn't apply to unpatched systems. I have been booting beta 1 with no issues since its release. (10.15.4 allows for WEG-enabled DRM for the RX 580.)
How did you upgrade/update? If I try through the Update utility it boots to a black screen so I have to reboot. On reboot I find out the blessing of OC is gone so it boots to Recovery for whatever reason. If I do upgrade through the DMG it either gets stuck in the beginning with the Apple logo screen or I completely loose the screen output (black screen). I haven't tried Beta1 only Beta4 and 5 and I got the same issue.
