Hi, I am using Clover right now with Catalina 10.15.7, I tried to use this EFI with the Open Core, but it is freezing on the Apple logo before the loading bar appears.

What more I need to do to migrate from Clover to Open Core?
Try to reset NVRAM first. You need to add some timeout time and ShowPicker to Yes. And boot with -v (NVRAM - Add - 7C436110-AB2A-4BBB-A880-FE41995C9F82 - boot-args - -v) to see where is your problem. Don't forget to update your system information under PlatformInfo - SMBIOS).
This is my last EFI. It is working fine for me.

I added the -v, and looks like some patches of I2C are not being found.

Those Coolstar patches are not ACPI patches. You can disable them on config.plist but I don't think that is your problem. Have you changed MacModel?
Please post your EFI
 
Here it is the EFI.

I was able to remove the not found errors but it still freezes, I suspect that the problem is related to the wifi board since I am using the DW1560, I tried to make some changes and add some bcrmrampatch and other things that people suggested but it continues the same way.

I think the line that show the error is third last one on the previous image.

What is your processor? 7500U?
I think SMBIOS Dictionary should not be on PlatformInfo.
SystemUUID is different on SMBIOS Dictionary
You have changed SystemProductName to MacBookPro14,2.

Yeah, I made some changes but still doesn't work. I give up, I'm going to stay with the Catalina for now and try again later.

Thanks for the help.
