Disabling VT-d worked! Thanks so much for your help @Middleman !!!

Any thoughts on why enabling this would disable wifi or what I could do to keep wifi working if I do enable it? I’ve tried multiple combinations of the CSM settings with no luck.

So I got another card and this one works after enabling CSM, but enabling CSM seems to disable my wifi. I tried putting the settings the way you have them. Once I unplug the card and disable CSM, wifi work again.

I got excited seeing this but had no such luck. Did you change any of the other settings in Compatibility Support Module? I see four items related to booting below the main one to enable After enabling.

I just got the same Sapphire Radeon Pulse 580 card. I installed today and set the same System Agent BIOS settings for VTD, PEG, and iGPU. Any ideas why I won’t get any video output using HDMI? I don’t even get to the BIOS logo screen or anything. Thanks in advance for any help provided.

Thanks @ctek Not sure if I am missing the post with the hot swap SSDT. I took the SSDT file from the original post when I built my system in July. I also checked Post #198 as mentioned in the original post June 27 update, but it only refers to Ethernet fix.

In Step 3 I am not getting "Populated: XHC: 15, AppleUSBXHCITR: 4" at the bottom of the list after entering my 15 ports. Instead I am getting "Populated: XHC: 15, pci8086,15ec: 4". (See attached screenshot). Is there something I am doing incorrectly?

So here are the changes I have made at this point: Added USBInjectAll.kext for now since I am installing Catalina. I will work on the USBMap after I get an install complete before I upgrade to Big Sur. Cleaned up kext folder and config file. To answer your questions I am using a SATA drive...

Thanks for your help whenever you can get to it. I am running out of things to try and search for. I am using HDMI. I thought the two DisplayPorts are Inputs. Is there a way to switch it to output to try that?

I set DevirtualiseMmio to False in Booter>Quirks as suggested in the Troubleshooting guide. It seems like it went further in the process, but I still see the [EB|#LOG:EXITBS:START] end.

Hi. So I worked on the switch to OpenCore last night. I attached the log from trying to boot with it as well as my config file. I am using iGPU. My screen also goes black at the end of the verbose.Have tried both 07009B3E and 00009B3E for AAPL,ig-platform-id.

Hi. I am using Clover and iGPU with this error. I started the setup for OpenCore, but it will be a while before I figure it all out since I am new to it. Was trying to get a working backup on Clover in the meantime so I would have a system to test OpenCore on while building the EFI folder and...

I finally made some progress after getting a different Catalina download. Now I am stuck at this screen in verbose.

Switching the USB port didn't help. I am using a 3.0 drive as well. Also tried removing one of my memory sticks from B1. Just have 16GB in A1. Things I have tried: Moving the memory stick to different slots. Different versions of Clover. Using OSXAptioFix3 instead of AptioMemoryFix.

I think I tried that but will try again when I get home. Also, is it still best to use a USB 2.0 drive, or does that not matter anymore?

So I was able to fix the USB being recognized. I still had the scheme as MBR instead of GUID Partition (silly me); however, I am now getting an end randomseed error “++++++++++++++++++” when trying to install using a Unibeast install drive. I’ve tried adding the SSDT and Kexts from the original...

Thanks for that. It was on Master Boot Record. Worked after switch to GUID. On to the next problem. I am just getting a bunch of ++++++++++++++ in verbose.

I am building a new system with an ASUS ProArt Z490 Creator board. My Unibeast USB install drive is not being detected. It says the system cannot find any bootable devices. I have tried multiple ports. Other bootable USBs can be detected if connected. I followed instructions on the main...

Hi. I am trying to build a new system with this board. I am unable to see my install USB for Catalina. I am able to see the drive on my old GA-Z68X-UD3H-B3 board though. I’m not sure if there is a setting I am missing.

I can't get this thing to wake over internet to save my life. It will wake on my local network fine but that doesn't help. I can't put it to sleep over internet also. It's almost like the port forwarding on my router closes once the computer goes to sleep. I had it working fine back with 10.10.3...
