Hi guys,

 

I'm trying to install Catalina on a Lenovo m720q (i5-8600T with B360).

After some other issues I'm know stuck at attached screen.

Im using latest opencore version and have my EFI folder attached.

 

Can someone help me I've got no clue what to try next :/ 

 

 

Cheers!

I've checked your EFI folder. It seems like you have left the legacy drivers in that folder.

Also, there's a shell.efi file there which seems unnecessary.

Try removing those and check.

Thanks! I've removed NvmExpressDxe.efi, AppleUsbKbDxe.efi and XhciDxe.efi and deleted shell.efi. still same message though.. any other idea?

I also faced this problem. Solved this by following the Intel Framebuffer patching present here - https://github.com/acidanthera/WhateverGreen/blob/master/Manual/FAQ.IntelHD.en.md

 

You can swap the 0xXXXXX code into ProperTree's data form by using this tool - https://www.scadacore.com/tools/programming-calculators/online-hex-converter/

 Make sure to use the DCBA version.
