If you OpenCore EFI already works on Catalina. Just follow the guide.

Thanks

 

 

Apparently you pasted all code together on Terminal. Try line by line.

Thanks for your help. May I suggest you highlight “Then run on Terminal (One line at a time)”

in a different colour?

After entering this line in Terminal - 

hdiutil detach `diskutil list |grep 'Install macOS Beta' |awk '{print $8}'` -force

Why am I getting this error as shown in the pic

 

Those <feff> not exists in the original command. Check your copy 'n' paste.

I was getting this error too. If I copy and past to the TextEdit it was ok but when I past it in Terminal I would get the error. I had to copy & past a few times to get it to work. I think it’s a bug in the OS

Try my OpenCore.efi and BOOTx64.efi attached to main post.

Probably.

Hi there,

I was hoping one of the experts here could kindly help me with my OC efi. I installed Big Sur with a real Mac and then Quit at the initial setup and installed it in my Hack. My Catalina OC efi works great but intantly fails with Big Sur. I tried the efi provided in the first post and it boots about 3/4 of the way and then an error keeps looping. I wonder if my efi can be corrected. Thanks

Hi. You need provide more information. What's the happening? What's error?

[fastfwd]

The posted efi in this thread gets stuck with the error posted below.

 

[ludufre]

@fastfwd Your PlatformInfo is very wrong! Did you pasted from Clover config.plist?

 

- DataHub and SMBIOS don't have to be here.

- Generic -> MLB, SystemSerialNumber and SystemUUID are empty.

 

I assumed that your platform is iMac18,2 (alright?). I generated SMBIOS with GenSMBIOS and fixed your config.plist

[fastfwd]

Thanks for looking into this. I get this the following error right at the start.

 

[ludufre]

@fastfwd Without knowing what's your processor, I made some changes. Try again:  config.plist

[fastfwd]

I thought my details were in my signature. I gave an i7500 Asus prime z270-a motherboard.I will try the new one

[ludufre]

@fastfwd Sorry. I didn't saw before.

I fixed a lot of errors in your config.plist.

The SMBIOS previously in your config maybe wrong. I think Kaby Lake processor need to be iMac18,1 with iGPU and iMac18,3 with dGPU.

Try this and tell me: config.plist

Hey @ludufre thanks for your help. I combined my Catalina info with your kext and updated smbios and oc 6 and I am in Big Sur right now. Only issue so far is audio.

This method of installation is very slow. Just wait. Mine take 50 minutes even with SSD.
