GPD-Win-Max-Hackintosh

Hello, everyone. This is a repository discussing about how to install Mac OS Catalina (or newer version) on GPD Win Max.

Thanks to all the volunteers who participated in this project. I don't have all their names, but without their effect, this repository won't be possible.

These are all the names I know.

One big guy for the initial version of EFI
Another big guy for working out the intel graphic driver
@THEDVIOUS1 for helping me work out the touch screen & touchpad driver
@lazd for the Goodix TouchScreen driver
@Azkali for providing p2max EFI for reference
@PeterCxy for giving some clues about how to fix some initialize problem of the touch screen driver
All the friend in a QQ group for providing many information and many improvment and doing many tests

Great thanks to everyone who participated in this project.

Changelog

20240118

Upgraded to Venture 13.6.3
Solder the BCM94360CS2 WiFi network card to the motherboard, enabling Airdrop and Handoff. -> Detail

20211002

Fixed boot screen glitch

20210515

Support "Smartisan TNT go" external display and type cover. Fixed the keyboard and trackpad issue. Added fn keymaps. You can install eqMac in order to control the volume of this external display, also it will works with all other DP external displays.

20210411

Added driver 360controller's System Preferences plugin of the built-in joystick, you may need to enable the "Pretend to be an Xbox 360 Controller" option to get the controller to work in some games. Just put the plugin builtin-joystick/Pref360Control.prefPane into ~/Library/PreferencePanes and you are all set. Note: I only tested this plugin under Catalina. I don't know if it works under BigSur. By the way, this driver's preference pane is very well polished. I'm loving it.

20210410

Fixed the touch event of external display's touchscreen rotated 270 degrees problem, by does not rotate the touch event at all (it's not a very good fix but it works under my usage ...), because the built-in screen is rotated 270 degrees and VoodooI2CHID did not consider this condition.
Fixed blue screen problem when booting windows 10 from Opencore

20210404

Finally fixed the "EL[0] was invalidated!!" crash by adding the igfxfw=2 boot argument. Thanks to @m0d16l14n1 for providing this information. I haven't encountered this panic for days.
Now the built-in joystick works, thanks to the project https://github.com/360Controller/360Controller. I have tested it in OpenEmu, steam, and Apple Arcade (tested the game shinsekai), it works very well. However, this driver says it does not support BigSur, and I only tested in Catalina, so I don't know if it works in BigSur. NOTE: You must switch the joystick mode on (push the joystick switch on the left of winmax to up) before you boot into macOS, otherwise the driver will not load. If you want to switch joystick mode when macOS is running, you may need to put 360controller.kext to /S/L/E and rebuild the kext cache. I don't want to do this. So I'm leaving it as it is.
Upgraded AirportItlwm driver, the speed at some conditions of 5Ghz wifi seems better, but I also encountered some connection problems and performance slowdown when using 2.4Ghz wifi.

20201226

Fixed battery remain time
Upgraded AirportItlwm driver
Modified VoodooI2CGoodix driver, now you can use the touchscreen like this
1. One finger drag set to scroll by default, one finger scroll direction is opposite to trackpad by default, so you need to uncheck Natural Scroll direction in settings
2. One finger long press to act as the original drag
3. Double-tap is fixed
4. If you prefer the original VoodooI2CGoodix driver, please use VoodooI2CGoodix.orig.kext in the efi/oc/drivers folder. You can find the modified code of this driver here https://github.com/kingo132/VoodooI2CGoodix.

20201219

Upgrade opencore to 0.6.4
Upgrade other drivers
Fixed goodix touch screen driver may fail to load at boot, now the driver can be load at every boot without problem

What's working

All USB port works include two type-c port. (USB3 works, speed is tested at 300MB/s read&write)
Both two type-c ports can connect to external type-c to DP or HDMI monitors. I have tested BENQ 4K monitor (4k@60hz) without any problem.
Joystick emulated mouse works.
Gigabyte ethernet port works.
The built-in keyboard works.
The Intel Iris integrated graphic card works, and the screen can be rotated 270 degrees by using ScreenResX or RDM. You can also hold Command+Option or Win+Alt before clicking Displays item in System Preferences to enable the rotate option if you don't want to install any additional software.
The speaker works, 3.5mm audio port also works.
Battery indicator works.
Sleep works perfectly.
Touch screen works
Build-in Game Controller works

What's working but have flaws

The built-in sd card reader works, but it may cause iStat menu to continuously print error logs like this.

deleted fsctl error: Inappropriate ioctl for device, using HARDCODED desired threshold ...

The only solution I found is to disable iStat menu disk monitor or do not insert or mount any sd card.

~~iStat menu may freeze during boot time, may be related to some hardware or driver issue. The most suspicious is itlwm.~~
Trackpad works, but it may fail randomly at some boots. Maybe it was the problem of VoodooI2C or I2C timing problem or kext loading race condition problem.
There are glitches on the screen when entering the desktop and shutting down.
Thunderbolt works but does not support hotplug. Maybe need to modify SSDT to adjust it to satisfy what mac os needs.
System may randomly crash with panic: "EL[0] was invalidated!!"@icl/sched5/IGHardeareCommandStreamer.cpp:64. or "Unexpected context status buffer entry"@icl/sched5/IGHardwareCommandStreamer.cpp:71. Easpically when connected to a 4k or 5k external display, or playing 3d games, or doing some other graphic heavy jobs. This is an IGPU driver problem. Currently don't know how to fix this. Have tried platform/device id 01005D8A/538A0000 and 0000528A/528A0100. Both will crash. It seems platform/device id 01005C8A/5C8A0000 and SMBIOS MacbookAir9,1 is the most stable combo.
Type-c USB3.0 HUB/Adapter may cause all USB in the system to fail if you plugged USB2.0 devices on it. Currently don't know the cause and don't know how to fix this. Both will fail before and after USB Customization.

- Related user feedback: https://discussions.apple.com/thread/251356598
- Workaround: Do not plug any USB2.0 device to USB3.0 Type-c HUB/Adapter. Plug them into a USB2.0 hub or plug directly into winmax's USB3 port.

What's not working

HDMI port is not working
HDMI audio is not working, technically, all the sound of external display is not working, includes type-c or display port.
- Besides the problem that icelake does not have native HDMI. Maybe this is the reason why type-c to Displayport also has no audio output to external display. See This Issue for more detail.

Extend the life of SD card

Disable SD card auto mount

Get UUID by using this command

diskutil info /Volumes/volume name

Add this entry to /etc/fstab. Note to change exfat to the filesystem type of your tf card. I'm assuming it is exfat.

UUID=<UUID get from piror command>   none  exfat  rw,noauto

Prevent spotlight from indexing the SD card

cd /Volumes/yourtfcard
touch .metadata_never_index

For those who want to upgrade the kext inside this EFI

Here are some kexts that you can not upgrade because I have made my modifications, it will cause the component to stop working if you replaced my kext.

360Controller.kext: I modified some bugs related to WinMax's built-in controller
AppleALC.kext: I modified the patch code of icelake device
VoodooI2CGoodix.kext: I modified bugs and added some functionalities
VoodooI2CHID.kext: I modified some bugs related to WinMax's trackpad and the external display's touchscreen

Modify BIOS settings

Note 1: We are testing under BIOS version 1.11

Note 2: This EFI can work without modifying bios setting, so this step is not a must-do step, you can skip it if you don't want to bother to dig such deep.

How to modify

Method 1: (the one I'm using) Modify BIOS varialbes using ru.efi. I have uploaded my BIOS dump file winmax_bios_dump.txt. You can find offset in this file and modify it using ru.efi. Try reading this guide. toturial
Method 2: (the most convenient one if you did the initial job) Flash a customized BIOS by following this video toturial. toturial
Method 3: (havn't tested) Use setvar of grub to modify BIOS veriables. Check this tutorial

The options need to be modified

cfg-lock: Enable -> Disable
Vt-d: Enable -> Disable
Dvmt: 60MB -> 64MB
EHCI Hand-off: Disable -> Enable

Other options that the default value is satisfied

above 4g: default is enabled
csm: default is disabled
boot mode select: default is efi
XHCI Hand-off: default is enabled

Other useful stuff
