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

Hey, I decided to follow this guide. Before starting I got a few questions:

1. I do not understand the point about "Broadcom BCM94352Z". What should I do with that exactly? Buy a peace of hardware or get drivers or what? How do I know if I have this on my laptop?

2. Making an OEM backup in a 32GB USB. I didn't find any guide on how to do that. I'm currently using Windows 10. How do I do this?

EDIT:

You mentioned that I need to find something about ELAN trackpads. What is it that I need to search for? I couldn't understand from the first post, so I'm quite worried about this one. My laptop uses ELAN trackpad and I don't know how to proceed when it comes to this step.

Also regarding WiFi... Do I need to replace hardware to make it work? How do I check this?

EDIT 2:

" If your laptop has the UHD/4K screen, set config.plist/Graphics/Inject/Intel=false for installation." ... How ????

"Definitely copy RealtekRTL8111.kext to Clover/kexts/Other" ... Where do I get this kext?

EDIT 3:

I assume that you are talking about switching the WiFI card altogether (physically). I have the intel one obviously so I need to switch to broadcom for better results. This is impossible for me right now. Can I still have WiFi with Intel wifi card?

EDIT 4:


This is my laptop exactly with same hardware and everything:

Read the links in the FAQ, so you know how to obtain the UEFI shell and run it.

The offset for setup_var are specified in post #1.

Hey,man

It seems that Lenovo has changed some components of Y50.
I bought a 4k model last month.
The one I got has an ALPS touchpad.
I tried the voodooPS2controller.kext, and only the functionality of click and right click works well.
No touchpad can be found in system reference setting.

what kext should I use for the function of touchpad such as two finger scrolling and three finger moving?
Thank you for your patient answer and awesome guide.

Hardware replacement.

Refer to documentation from Lenovo.

Use google to find PS2 kexts for ELAN.

Edit config.plist with a plist editor such as Xcode or PlistEdit Pro.

Intel WiFi is not supported. Hence the need to replace it.

It seems no ssdt file is generated.
I have put clover into HDD.
The config file I used is attached here.

Please follow the guide carefully and exactly. In order to extract native ACPI files, you must boot from USB prepared according to the guide. And the final config.plist should not be used until ACPI patching is finished.

You're not getting SSDTs extracted because you're booting with a config.plist that specifies DropOem=true.

Follow the instructions for re-patching in post #1. You need to do 'make cleanallex' as you now have invalid patchmatic -extract results in native_patchmatic.

sorry to bother you but I googled for whole night and haven't found a proper kext for ALPS.

it seems the author stops upgrading it.
Can you help with this ?
ALPS on my laptop supports up to 5 fingers, it will enhance the experience a lot.
Thank you!

Amazing, nearly everything works well except I can't turn my Bluetooch off no mater how I press TURN OFF in system setting. It is very strange. The first time reboot after I finish installing, I can turn BT off. After that I only install some kext for ALPS with KEXT WIZARD. And suddenly I found I can't turn BT off.

I changed another KEXT WIZARD, and repair disk permission again, I still can't turn it off!
Help me please, thank you!

I have no ALPS hardware. There are many different versions around, so you'll have to search extensively.
