You need to inject the required properties for your Broadwell HD5500. Follow the configuration you'll find in existing guides for Broadwell laptops that are available on the forum. You may also consult the WhateverGreen manual for guidance.


Not much further we can provide until you post a zipped copy of your bootloader EFI folder or config for checkup.


Given that HD5500 iGPU of i3-5005U CPU carries id 0x1616, all you would normally require in terms of properties injection for [email protected] would be:

framebuffer-patch-enable        01000000        DATA
framebuffer-fbmem               00009000        DATA
framebuffer-stolenmem           00003001        DATA

WhateverGreen kext then taking care of everything, including the correct BDW framebuffer layout. SMBIOS MBP12,1 of course!
