OpenCore EFI for Lenovo Y50-70 (FHD-1080p and UHD 4K) updated for Monterey

Buy me a cup of coffee to support my work, thanks! Buy Me A Coffee

## Updated to OpenCore 0.7.8 ### Added support for Monterey

For Monterey use Monterey EFI, for BigSur use BigSur EFI

For installation, use PRE-EFI.

After installation, use POST-EFI.

Before using this EFI, make a copy of your EFI and read Notes section carefully.


  • Intel Core i7-4710HQ
  • Intel HD4600 integrated GPU
  • Nvidia GTX 860M 4GB (unsupported)
  • 16GB DDR4 Ram
  • Broadcom BCM94352Z (Network card)

For UHD:

  • Use Config-UHD.plist, but you need to delete Config.plist and rename Config-UHD.plist to Config.plist

For Dual Boot:

Note: After resetting NVRAM, you need to do the steps from 4 to 6.

  1. Make sure that Microsoft is in the same folder as BOOT and OC

  2. Boot to Windows from BOOT MENU

  3. Download EasyUEFI

  4. Open EasyUEFI and click Manage EFI Boot Options

  5. Click the Create a new entry icon (second icon from the center column)

  6. Do the following:

    1. Select the Type: Linux or other OS and write as description: OpenCore
    2. Select EFI as target partition
    3. Click browse and locate the OpenCore.efi file and click OK
    4. Click OK again to add the entry
    5. Once the entry is added, click on OpenCore and start clicking the arrow up button (first button from the center column) until OpenCore appears on the top of the table.
  7. After doing this restart your laptop and you will see opencore booting as priority option.

  8. Boot to Big Sur

  9. Download OpenCore Configurator (OCC)

  10. Open your Config.plist with OCC

  11. Go to Misc and click Entries tab

  12. Click + button on the right bottom. A new entry will be created and you will see a browse button

  13. Click the browse button and for windows users, go to your EFI folder and locate bootmgfw.efi (\EFI\Microsoft\Boot\bootmgfw.efi) and click open

  14. Change the entry name from bootmgfw to Windows

What works:

  • Dual Boot with Windows
  • Disabled OC injections with Windows (Fixed the issue with Lenovo Vantage recognizing your Lenovo as a mac)
  • built-in keyboard
  • built-in trackpad (multi gestures)
  • HDMI video/audio with hotplug
  • AirPlay mirroring to AppleTV
  • native WiFi & Bluetooth via BCM94352Z
  • native USB3
  • native audio with AppleHDA
  • built-in mic
  • built-in camera
  • native power management
  • battery status
  • backlight controls with smooth transitions, save/restore across restart
  • accelerated graphics for HD4600 (both 1080p and 4K)
  • wired Ethernet
  • retina scaling
  • Sleep/Wake
  • Auto Brightness Sensors
  • iMessage & Facetime
  • Brightness keys on keyboard (Fixed by migrating from ApplePS2SmartTouchPad.kext to VoodooPS2Controller.kext)
  • Built in Card Reader with Sinetek-rtsx
  • USB Tethering iOS and Android Devices
  • FileVault (Not recommended as you may encounter some bootloops, but it's there)


  1. Download GenSMBIOS
  2. Do the following:
chmod +x GenSMBIOS.command
  1. Install MacSerial
  2. Generate SMBIOS
  3. Type MacBookPro11,4 (You can use anything from 11,1 to 11,4)
  4. You will get your SMBIOS: Type, Serial, Board Serial and SmUUID.
  5. Edit your Config.plist either with OCC or Xcode or TextEdit:
    i. Type to Generic -> SystemProductName
    ii. Serial to Generic -> SystemSerialNumber
    iii. Board Serial to Generic -> MLB
    iv. SmUUID to Generic -> SystemUUID


  • Before creating an issue, please check if there is an open/closed one already related with your issue.
  • In order to use iMessage and Facetime, try using MacPro7,1 or see #12, #17.
  • For those having issues with the display color, for some users the display color have a light brownish tint.
    In order to fix this you need to calibrate your display colors, by going into display settings from system preferences, then click calibrate from the color tab.
  • You may need to modify keys for the keyboard. For me the command was swapped with alt button (windows button on keyboard). So in order to fix this do the following:
    1. Go to System Preferences -> Keyboard -> Modifier Keys
    2. Change Option Key to Command
    3. Change Command Key to Option
  • If you have ALPS trackpad use the ALPS-VoodooPS2Controller.kext, but rename to VoodooPS2Controller.kext so that you won't end up having a bootloop.
  • FileVault can be enabled from System Preferences, but it is recommended to leave as it is (turned off).
  • Fix for § to ~ (Tilde key)
     Open System Preferences -> Keyboard -> Change Keyboard Type -> Continue
      -> Click the tilde key -> Selet ISO as Keyboard Type -> Done #41


@akavkl - Integration of HoRNDIS and FileVault #28
@dxkrs - Tilde key fix #41
