What boot args are you using?

 

[fredherbert]

u can see it in the efi but its: -v keepsyms=1 debug=0x100 alcid=11 agdpmod=ignore

Change agdpmod=ignore to agdpmod=pikera, as that us the boot argument used to prevent black screen issues with Navi GPUs.

 

[fredherbert]

i changed it and now im stuck here

 

[Edhawk]

Try using both boot arguments.

You shouldn’t need agdpmod=ignore with your B550 system, but it may be helping.

 

[fredherbert]

? i think you may be confused with another person my chipset is A520, not B550

 

[fredherbert]

i got past the error but im back with no video output

 

[Edhawk]

No I am not confused, I just rushed the reply. Saw A520 but wrote B550. Doh!

Still shouldn’t need agdpmod=ignore boot argument for your system no matter which macOS version you use.

haha, no worries, i fixed it tho, i remade my EFI i changed to macpro 7,1 and it works perfectly, only audio doesnt work. its alive!
my boot args was -v keepsyms=1 debug=0x100 alcid=1 agdpmod=pikera unfairgva=1 and it worked

Your MSI A520-A Pro motherboard uses either the Realtek ALC892 or ALC897 codec. You will need to check this in Windows or Linux to confirm which audio codec is in use.

AppleALC.kext includes a number of layout ID's that work with these codecs.

Layout ID's for the two codecs

Unfortunately there isn't a custom layout-id for your MSI motherboard, so you will probably need to use a generic ID, which may not include all the audio options available on your system. Layout's 1, 2, 3, 4, 5, & 7 tend to be non specific audio configurations. All the higher numbered ID's will be custom audio configs.

what open core options did you check to create a macpro 7,1? just wanting to double check as I tried this and am not sure I did it right.

Read this section of the Dortania Ryzen guide.

Ryzen and Threadripper(17h and 19h) | OpenCore Install Guide

FYI, If you are using a real MacPro5,1 then this isn’t the guide you need. You need to read up on using OCLP, which you have probably already done.

Have a look over at MacRumors, they may have more info about keeping your MacPro5,1 alive with the latest macOS releases. The threads below and others might hold the answers you need.
