Laptop configuration

  • Audio : The Sound Card is Realtek ALC255, which is driven by AppleALC on layout-id 3.
  • CPU : The CPU model is i5-8250U and XCPM power management is natively supported.
    • XCPM and HWP are recommended to work together to reach better power management, by injecting plugin-type=1 with SSDT-XCPM, and using CPUFriend.kext.
  • Graphics : The iGPU is Intel UHD Graphics 620, and its enabled using Ig-Platform-id=0x191E0000.
    • The discrete dGPU is NVIDIA GeForce MX150, and it is disabled because macOS doesn’t support optimus technology. Plus battery life is much improved.
    • The colour branding or corrupted colour depth is fixed with Intel Skylake spoof and EDID fix.
    • Native brightness hotkey support using DSDT.aml.
  • Battery : Battery Management using SMCBatteryManager.kext.
  • Backlight : Native Brightness control using SSDT-PNLF.aml.
  • Ethernet : Gigabit Ethernet using RealtekRTL8111.kext.
  • HDMI : Intel Framebuffer patches to change the connector-type to match the physical connector, using WhateverGreen.kext.
    • HDMI Audio : Injecting property "hda-gfx" = "onboard-1" on HDAU, IGPU, HDEF objects & also injecting layout-id 3 on HDAU to match layout-id on HDEF.
  • Touchpad : Native I2C touchpad support using VoodooI2C.kext; Set touchpad Mode to Advance from BIOS & All gestures will work fine.
  • USB : Custom SSDT-UIAC.aml SSDT for USBInjectAll.kext that configures USB ports on XHC such that the port limit patch is not needed, and each UsbConnnector value is correct for each port.
    • You can also find USB port mapping for SSDT-UIAC Here.
  • Wi-Fi : Stock WiFi Card is Atheros QCA9377 It is not supported on MacOS.
    • Best Choice will be to replace current Card with BCM94352Z which has WiFi+BT, or . You can find it on AliExpress for like $20-30. I Have already changed my current WiFi card with BCM94352Z (Lenovo's 04x6020).
    • This BCM94352Z card comes from 2 manufacturer called:
        1. DELL – mainly called DW1560 – has A key NGFF notch – much expensive
        1. Lenovo – mainly called 04x6020 – has E key NGFF notch – not so expensive
    • The Dell’s DW1560 is much expensive and is only recommended for laptops with A key NGFF notch & also laptops which have whitelisted cards from certain vendors.
    • On the other hand Lenovo’s 04x6020 has E key NGFF notch and is much cheaper than DW1560.
    • This laptop supports both & you are free to choose between the two.
    • Keep in mind, this laptop uses M.2(NGFF) Socket with A+E Key. Half size card won’t work.
    • Config.plist is already patched for BCM94352Z and BCM943602BAED & added kexts for BT as well.
  • Bluetooth : Stock Atheros QCA9377 BT will work out-of-the box, But you can’t turn it off because BT power management is not supported;
    • To Fix this you’ll have to get a MacOS compatible WiFi+BT card. The best choice will be BCM94352Z which has WiFi+BT.
  • SD Card Reader : Internal SD Card Support using Modified Sinetek’s rtsx Driver.
