[Solved] Dell XPS 13 7390: Cannot boot past OpenCore


Recommended Posts

Hey, I've been trying to boot the macOS Catalina installer for some time now but always been getting stuck on the following message at the end of the OpenCore boot process.

09:366 00:035 AAPL: [EB|#LOG:EXITBS:START] 2021-08-15T07:54:09

I've made sure to turn off any problematic settings in the BIOS according to the Dortania Laptop Comet Lake guide (including MSR and CFG-Lock)


EFI.7z opencore-2021-08-15-075346.7z

That got it to boot into the kernel!
Though it seems to be getting stuck either on Thunderbolt (which is completely off in the BIOS), or the ACPI errors)



I was able to eliminate the ACPI errors by using the correct .aml's from Dortania (was previously using ones created by SSDTTime)
Though it's still stuck in the same spot of the boot process.

Your EFI got stuck in the [EB|#LOG:EXITBS:START] part again, but the moment I placed the Cpuid1Data and Cpuid1Mask values into the config.plist it booted into the installer! 😎



Time to enable the NVME drive and see if it installs.
