Notes:
- * dGPU is NOT supported on macOS due to the Optimus configuration, hence it's disabled by the
-wegnoegpuboot flag. HDMI is wired through iGPU, though. - ** The kext
ApplePS2SmartTouchPad.kextactually covers all the Synaptics/Focaltech/etc. trackpads. - *** Those are NOT supported on macOS, and they're replaced by the "suggested" counterpart.
- **** Proper patches/kexts are already added in this EFI. If you have a different card, remember to remove those!
Tested on
- macOS Big Sur (11.6 - 11.6.1)
- macOS Monterey (12.0.1 - 12.2.1)
What's working:
- Audio (Speakers + External devices)
- Battery percentage (Optimized charging too)
- Bluetooth*
- Boot through HDMI**
- Brightness (including brightness keys)
- Ethernet
- FN Keys (except F2 and F9 unless you use AsusSMCDaemon)
- HDMI plug-and-play
- HDMI audio
- iGPU (full QE/CI)
- Internal microphone
- Keyboard
- Sleep/Resume**
- Trackpad (with some gestures)
- USB (both 2.0 and 3.1 gen2)
- WIFI*
Notes:
- * refers to the BCM94352HMB card.
- ** After booting/resuming through HDMI, you'll experience a "glitch". Just open/close the lid and the issue disappears.
What's not working
- After sleep/resume, Bluetooth may become unavailable. That's a known Monterey bug, I can't do anything to address it. Meanwhile, you can just reboot to let it work again.
How to use it
- Download the latest version of OpenCore from here
- Place those files inside OC folder
- Remember to generate a new SMBIOS through GenSMBIOS and put it using ProperTree following this guide. Remember to put an AppleROM too! It's important in order to let macOS recognize properly the device.
- Put both OC and BOOT folders inside a new EFI folder
- Lastly put the EFI folder inside your USB/drive EFI partition and reboot!
Useful infos
- I've already added the latest HoRNDIS kext in order to use an Android phone (via USB tethering) for connecting to internet.
- If you can't type proper characters using your USB keyboard, try switching Key Rollover method (if any), from N-Key rollover to 6-Key rollover. Seems that macOS has some problems in recognizing correct characters while using N-Key rollover.
- The EFI does actually boot across all tested versions. Bluetooth with the mentioned card works too in all versions.
AppleXcpmCfgLockis set to true for better compatibility across all BIOS versions. Though, after unlocking theMSR 0xE2 register(aka CFG Unlock), you can disable it for better performances.- Virtualisation is enabled by default, you can keep VT-d on. VMWare works fine too!
- The kext
ApplePS2SmartTouchPad.kexthas been tuned properly to work with a natural scrolling method, plus some gestures has been enabled. You can tune it by yourself by editing theInfo.plistfile inside the kext itself. - You can use Camera Controller in order to tune the integrated webcam (eg. increase brightness).
