Yeah the restart and shutdown doesnt work! How can i fix that? I've tried a few but still get the same issue How would I go about fixing the USBs? I've used the files from @Ploddles efi but they are still slow opencore-2020-11-14-115258.txt.zip

I also made a new USB with the DEBUG version of OC as someone suggested in order to get the MMIO ( i dont know if that's what we've been doing with Fabiosun yesterday ) but maybe it could help to sort the issues ! DEBUG.zip

So I've spent all night yesterday trying to solve the unpredictable black screen that happens before the login appears but I couldn't figure out. Sometimes , I restart and it loads right away Also, the USB shows as 3.1 but when I've done some speed tests it writes with 15mbs or something. What i did is used @Ploddles ACPI and added those to my working config but it doesn't seem like it works as it should. Am i missing anything? I also tried to copy the MMIO whitelist @fabiosun made for my working config and replace it in @Ploddles OC 6.3 config but I still get the same error I got initially with MACH Reboot Any ideas?

I will experiment tonight with a copy of the EFI to see how it turns out! Once again, thank you so much for your amazing help. Feel blessed to have the support of this community!

Yeah very strange ! How do i do that? Sometimes I have to unplug the hdmi and replug it and it works . There is only 1 hdmi port , the other ones are display ports ( i dont have a monitor with dp) It boots without the pikera and without Whatevergreen . Just "-v"

Thank you ! Im still so confused why it takes so long.. sometimes i have to take off the HDMI and put it back and it shows the login screen. I've uploaded a video!

So this one works fine and it didnt crash yet! The only issue is that it takes too long to boot. I'll take a video and upload it on youtube so you can see! opencore-2020-11-13-163310.txt.zip

I've tried again but still the same error ! Latest bios right? It gives me this error first then the usual MACH reboot

OMG! It didn't crash yet ! You are a god! The only weird thing is that it takes too long to boot and the logic screen takes about 20 seconds to turn from black to normal! Is that something that could be fixed? THANK YOU THANK YOU!!!

The last config i just tried boots to a black screen. ( I checked and it still has the agpmod ) . I will try the last one ! opencore-2020-11-13-154424.txt.zip

Still the same.. boots up and freezes around a minute later. It's so weird that it's always at the same time! Also, I've noticed that it's a bit slow while it's booting. When i click MacOS to boot it takes about 10 seconds to start showing the verbose mode You have no idea much I appreciate your help. I would be lost ! opencore-2020-11-13-152306.txt.zip config.plist.zip

Same BIOS , the latest one available for the Aorus Xtreme and CSM OFF . I've tried with on and it gets stuck before booting With the latest config and the AMD flag it boots normally and then randomly just freezes after about a minute. LOGS.zip

Ill try that now! With the latest config , it booted to a black screen again LOG.zip

Will do! Thank you! AMD 5700XT

I haven't modified anything ! Just wanted to inform you that i changed the graphics card just in case 🙂

I still get a black screen with this config. Is the nv_disable for the 5700xt as well? i removed the gtx opencore-2020-11-13-142741.txt.zip

I added : agdpmod=pikera and it booted but it froze again after a minute! Where can i find the bootleg.txt? I don't see anything , i searched for it as well opencore-2020-11-13-141108.txt.zip

It booted but then I have a black screen. Computer is still on. Should i post the bootleg? ( I have the 5700XT now btw )

So with the same EFI , and the 5700 xt , it recognises the graphics card and the graphics look normal but it freezes after a minute again!

Yeah I didn't mix them ! Just wanted to try Borrowed a 5700xt from a friend now and im gonna give it a try! Thank you!

Would the 5700XT be natively supported? I made a new USB with Big Sur and @Ploddles efi but still get the same error like before. MACH Reboot

So tempted to just go buy a graphics card now... Here's the one that boots up with good graphics then restarts after a minute! ( the network kexts are not the proper ones but i can easily fix that later ) Thank you ! EFI- Latest.zip

So now it booted but with glitchy graphics again and it says Nvidia Chip Model 8 MB. But now instead of restarting it froze. I will try with CSM to see!

Boots fine and the graphics work normally but after 1 minute , it randomly restarts! Is there a way to get the error message?

Fingers crossed!! I tried putting # in front of mmio and adding the smbios details but now it shows some text flashing by then restarts. config.plist.zip
