macOS on X1 Carbon Gen 2

A project using Acidanthera's OpenCorePkg and Dortania's Opencore-Legacy-Patcher.

My main goal with this is get unsupported macOS versions and features up and running on this hackintosh after hardware support has been lost using OCLP

---

Notable features of this EFI:

• Compatible with macOS Sonoma
• Working WiFi + Bluetooth
• Working Touchscreen (if available)
• GPU Acceleration (Only with OCLP)
• iCloud Services
• YogaSMC support for features like CPU fan control, performance bias, most Fn Key shortcuts working, additional OSD overlays, etc.

---

Issues:

• macOS will not display properly at native 1440p resolution
• Adaptive row will not wake up after system has been woken up from sleep
• USB ports will sometimes complain of high power usage

---

Future Goals:

• Fix adaptive row issue
• Fix native 1440p screen glitching issue
• Add better GPU framebuffer patch
• Improve CPU power management for better performance and battery life

---

Caution

Upgrading from to macOS 14.3.1 to 14.4 or up via System Update causes a Kernel Panic during install! Disable AiportItlwm and enable itlwm instead. Set SecureBootModel to Disabled, Reset NVRAM and run the update again. If this does not work, follow this workaround (Thanks to 5T33Z0 for this) to install macOS 14.4 on a new APFS volume. Use Migration Manager afterwards to get your data onto the new volume!

Get Started!

Important

If you haven't already, I recommend going through the Opencore install guide once to fully understand everything that is going on here and to help with troubleshooting incase of any problems

Prerequisites:

• Any plist editor (Highly recommend Propertree)
• GenSMBIOS to generate SMBIOS information (Use MacBookPro15,2 only as the USB map will not work with other SMBIOSes)
• OpenCorePkg for access to it's utilities, specifically macrecovery to download an online macOS installer if needed
• Opencore Legacy Patcher as it is required for enabling GPU acceleration right after installation
• YogaSMC
• MountEFI
• A compatible storage medium

Instructions:

• Download the latest version of the EFI
• Extract it and place the EFI folder in the root of your USB drive
• Open config.plist using a plist editor
• Generate SMBIOS information using GenSMBIOS and paste it into the config.plist
• Optional:
  • Edit boot-args to your liking.
    • Add -v, debug=0x100 and keepsyms=1 to help with debugging incase of any issues
  • Tweak your config.plist to your liking. Most users will not need to do this
• Save your config.plist
• Navigate to the Opencore folder and go to Utilities/macrecovery
• Open a terminal in this folder and download the latest release of Sonoma. (Refer here on how to do so)
• Place the com.apple.recovery.boot folder in the root of your USB after downloading
• Optional:
  • Place MountEFI, Propertree, YogaSMC, Heliport and OpenCore-Patcher in a separate folder on the USB. This will help save time later on
• Reboot to the BIOS and follow below

BIOS Configuration

Tested on BIOS version GRET63WW (1.40) and EC version GRHT39WW (1.20) Change settings so your BIOS looks like this:

Category	Setting
Config	Network Wake On LAN: Disabled USB USB UEFI BIOS Support: Enabled CPU Intel (R) Hyper-Threading Technology: Enabled
Security	Security Chip Security Chip: Disabled Memory Protection Execution Prevention: Enabled Virtualization Intel (R) Virtualization Technology: Enabled Intel (R) VT-d Feature: Enabled Anti-Theft Intel AT Module Activation: Disabled Computrace Module Activation: Disabled Secure Boot Secure Boot: Disabled
Startup	UEFI/Legacy Boot: UEFI Only CSM Support: Yes Boot Mode: Quick

Caution

Test drive your configuration once using a USB flash drive before you move it to the main EFI partition. I am not responsible for a broken OS/loss of data, etc...

Important

If you have a 1440p display and upon booting into the macOS or the installer you have a garbled screen, add -igfxvesa to boot-args in your config.plist. It is required to remove it later on and switch to a lower resolution if you want graphics acceleration. Do note that macOS Sonoma and up will boot automatically with no acceleration and so it's not required to add this boot argument

Post Installation

Congratulations you've successfully booted your hackintosh! Here's some things to do before moving forward:

Important

Remove the -igfxvesa boot argument from your config.plist if added. It will be hard to see but navigate to System Settings and turn down the resolution to anything below 1440p

• Graphics Acceleration:

  • Open OpenCore Legacy Patcher
  • Allow all the necessary permissions and click on Post-install root patches
  • It should automatically bring up a patch for graphics
  • Install and reboot and you should have graphics acceleration

• YogaSMC:

  • Open the YogaSMC .dmg file and install the .prefpane and move the app to your applications folder
  • Open YogaSMC and in the menu bar, click on Start at Login
  • Open System Settings and navigate to YogaSMC settings and you're done!

• Booting without USB:

  • Open MountEFI
  • Mount the macOS EFI partition
  • Copy your EFI folder from the USB to the EFI partition now available
  • Reboot your machine without the USB plugged in

• Heliport:

  • This is only if you are using the itlwm kext
  • Open Heliport and install it
  • You should now be able to connect to WiFi

• Additional:

  • Open System Settings and navigate to Battery

  • Scroll down to Options... and do the following:

    • Enable Power Nap: Never
    • Put hard disks to sleep when possible: Never
    • Wake for network access: Off

  • Run the follwing, one line at a time:

    sudo pmset autopoweroff 0
    sudo pmset powernap 0
    sudo pmset standby 0
    sudo pmset proximitywake 0
    sudo pmset tcpkeepalive 0
    

• Beauty Treatment (Optional):

  • In config.plist
    • Remove -v from boot-args to turn off Verbose Mode
    • Turn off the picker
    • Change the scan policy to 2687747 to hide all NTFS drives from Opencore
    • Turn on Auto login
