<< Solved >> [Help] Dell 7573 Opencore can't get to installer

[michmill]

I've been trying for a week now to get to the MacOS installer screen. I've read and re-read the Opencore os-vanilla-laptop guide, and have created the installer USB and plist countless times. This is my 5th or 6th hackbook, but the first with Opencore. Any advice on how to get a clean boot to the MacOS installer screen is greatly appreciated.

Behavior:

1. Boot USB
2. Select "Install macOS Catalina (external)" option in Opencore boot menu
3. 1/2 a page of debug messages appear (attachment below)
4. Boot freezes

Specs:

• Dell 7573 (1920x1080)
• Core i7-8550U (Kaby Lake/Coffee Lake southbridge)
• Intel integrated UHD 620
• 16 GB RAM
• SK hynix SC401 M.2 SATA 512GB

Versions:

• Opencore 0.5.7 Debug
• macOS 10.15.4::1 refresh

Base settings:

• Using MacBookPro14,3 SMBios
• AAPL,ig-platform-id=0000C087
• device-id=C0870000

Steps taken so far:

• Clear NVRam (Multiple times)
• Different SMBios 14,1 14,2 15,2
• Rebuilt USB and EFI multiple times

Attached are copies of the boot log, and a .zip of my EFI folder (I'll replace the SMBios info later to preserve privacy)

Do you ended up in a stop sign?

 

[michmill]

No, I don't get a stop sign. It just hangs. I let it sit for 20 minutes. Also, the USB drive has an activity indicator, and it doesn't blink after it hangs.

I made it a little further. The issue was I had to enable Booter->Quirks->DevirtualizeMmio.

Now it's time to resolve the next kernel panic...
