Alienware Aurora R6: Big Sur with OpenCore 0.6.4

Hey there. I'm trying to make a fresh install of Big Sur to my desktop, also did some upgrades to it. But I'm getting the following error preventing me to get to the installer. 

"macOS Utilities[635:2647] *** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArray0 objectAtIndex:]: index 0 beyond bounds for empty NSArray'"

 

These are my specs:

  • Motherboard: Alienware 07HV66 A00
  • CPU: Intel Core i7 7700
  • RAM: 16 GB 2133 MHz
  • GPU: ASUS RADEON RX 5700 XT 8GB
  • SSD: Intel SSD 660p Series 512GB
  • HDD 1TB 7200
  • Audio: Realtek ALC3861
  • Ethernet: 10/100/1000 Mbps Killer E2400

 

Notes:

  1. Generated SSDTs and DSDT with this SSDTTime.
  2. SMBIOS is set to iMac18,3 due to dGPU, was added to config.plist using GenSMBIOS.
  3. I was running dual screen but instead of the error got stuck on a gray screen with the mouse.

 

I also attach my EFI folder and the installer error log.
