Dell Inspiron 759x

System configuration

About build

• You need at least Macos 10.15.5 to boot with SMBIOS 16,1
• Intel wifi card is finally worked:
  • Follow this: https://openintelwireless.github.io

Performance

• Geekbench 5: 1052 SingleCore, 3935 MultiCore
• Battery: 57wh with 87% health and 60% brightness (2 NVME and 1 SSD SATA), I got 3h20 screen time when suffering web and light code

Not Working

• Thing may never work:
  • Discrete GPU (Disabled)
  • Fingerprint (Disabled)
  • Internal Microphone

HDMI blinking at boot

This will happen when using plug-in HDMI after bootup. This will be fixed after short sleep (about 1min) and never happen again until reboot

• You can fixed this by turn off com.apple.driver.AppleHDAController in Kernel and Kext Patches on Clover or Kernel > Patch on Opencore but HDMI Audio will be disabled

From 10.15.6, event 11, HDMI audio is dead, still finding solution

For building

This will pull all newest kext and build into zip files

• Clone this repo
• Run follow command: python3 update.py --build
• Get your build at Builds folder

Installation

BIOS

• Disk in AHCI mode
• Fastboot: Thorough
• Power on lid: Disabled - Fix black screen after wake
• Disabled thunderbolt auto switch and select it to BIOS assist for better battery management in Catalina and BigSur

STEP

You can follow Dortania's guide as it very detail and easy to understand.

Short once

• Prepair an Mac installer in USB with bootloader you choice ( Use unibeast to create it )
• Go to release and download lastest version of your choice ( Clover or Opencore )
• Replace EFI folder in USB EFI partition with this shipped EFI folder ( find the folder with name is EFI from zip file)
• Boot into USB and select MacOs installer
• After install success, run PostInstall/install.sh in terminal
• Then you need to mount EFI partition and replace it with USB's EFI
• After System EFI replaced by your EFI, Using Opencore Configurator, Clover Configurator or update script to change SMBIOS, generate your serial and MBL
• If you're using intel card, please use NullEthernet for fixing iMess and FaceTime - Change MAC in NullEthernet with your new created one, see below
• For intel wifi card's user, follow Intel's guide for init your wifi

Fake ethernet

• Generate your MAC address in SSDT-RMNE if using NullEthernet
• You can make an MacAddress in Mac generator online
• Edit SSDT-RMNE.aml with MaciASL and replace MAC with your generated one
• Save as -> ACPI machine language (replace exited one)
• Add it to your bootloader:
  • Kext add in Kexts:
    • Copy kext to kexts/other if using Clover
    • Copy kext to Kexts and add it into Kernel in config.plist (Use OpencoreConfigurator)
  • AML's file add to ACPI folder (Opencore need add to ACPI after copy SSDT file to ACPI, use OpencoreConfigurator)
• Reboot

Sleep Wake

sudo pmset -a hibernatemode 0
sudo pmset -a autopoweroff 0
sudo pmset -a standby 0
sudo pmset -a proximitywake 0
sudo pmset -b tcpkeepalive 0 (optional)

-b - Battery -c - AC Power -a - Both

Please uncheck all options (except Prevent computer from sleeping..., which is optional) in the Energy Saver panel.

Display

If you are using FHD(1080p) display, you may want to enable font smoothing, run this command from terminal:

defaults write -g CGFontRenderingFontSmoothingDisabled -bool NO

If your laptop display is 4K screen, you should set uiscale to 2:

• Opencore: NVRAM -> Add -> 4D1EDE05-38C7-4A6A-9CC6-4BCCA8B38C14 -> UIScale -> 2
• Clover: BootGraphics -> UIScale -> 2

Using DW1820a as wifi card

• You have to do following changes to Device Properties or it cant boot into macos:
• DW1820a now have been supported by AirportBrcmFixup, if u facing with connection issues then follow bellow

Change

<key>#PciRoot(0x0)/Pci(0x1c,0x0)/Pci(0x0,0x0)</key>

Into

<key>PciRoot(0x0)/Pci(0x1c,0x0)/Pci(0x0,0x0)</key>

• See THE Solution:Dell DW1820A
• Other card you may need google for it

NTFS Writing

Add UUID=xxx none ntfs rw,auto,nobrowse to /etc/fstab, xxx is the UUID of your NTFS partition.

If your NTFS partition has Windows installed, you need to run powercfg -h off in powershell in Windows to disable hibernation.

Tap Delay

• Turn off Smart zoom to avoid two-finger tap delay.

See is-it-possible-to-get-rid-of-the-delay-between-right-clicking-and-seeing-the-context-menu

BIOS value unlock (Advanced User)

Big thanks for @Leoing, who found all nessesary value

You can follow this to change those value

For Bios 1.6.0 0x78C need set to 0x0 so VoltageShift can be used

You can use mine SmartCPU Script base on VoltageShift for controlling cpu power's usage: SmartCPU
