[Guide] Lenovo Y50 (UHD or 1080p) using Clover UEFI

[abhikbhatia]

Enter in the BIOS and put Legacy support and leave Uefi First

I checked, and those two are already set

Your ioreg indicates you have BCM94352. It is the recommended WiFi hardware.
Other recommendations you can find in the FAQ:

Okay I followed the guide and again the internal display is not working but external does. Please let me know what I can do to fix this. I've been trying to get this to work for months now but I honestly can't figure out what it is I am doing wrong.

This setup looks ok.
Make sure you have correct BIOS settings.
And make sure you set DVMT-prealloc to 128MB.

Note: You might try OsxAptioFixDrv-64.efi instead of AptioMemoryFix.efi.

As far as I know, the bios options are already set. Can you please confirm if this is how it should be? For reference, I have legacy support on and uefi first.

Neither of those images shows CSM/legacy/UEFI options.

You should set BIOS to default, then change only the items as mentioned in the guide.

I set the bios to default and did as instructed again. Screenshots are in imgur link

the last image shows that secure boot option shows up only when I have boot mode to UEFi otherwise if I have it set to Legacy support and UEFI first, secure boot option to disable it does not show up

It is as expected.
Secure boot cannot be combined with legacy (legacy is always not-secure).

Okay cool. So what are my options from here then? Is there anything else I can do to fix this display issue?

You might experiment with your IGPU settings.
From reading post #1, it seems you're not using the correct version of BIOS, so that may cause problems.
