For my setup, using OpenCore 0.6.6, my UpdateSMBIOS value was set to false, preventing this fix from fully working on my XPS 13 9360. Once I set all three values to the correct setting then the Dell SMBIOS truncation issue was resolved.
CustomBIOSGuid > Yes/True
UpdateSMBIOS > Yes/True...
Hello, I'm working on a 9360 that I just picked up, can't get the USB drive to get to the installer; trying for OC 0.6.6 and Big Sur 11.2.
Here's the CPU/GPU:
