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.
CPU Brand Name: Intel(R) Core(TM) i5-1035G7 CPU @ 1.20GHz, Max Turbo 3.70GHz
CPU Code Name: Ice Lake-U
Motherboard Model: GPD G1619-01
Memory Capacity: 16 GBytes @ 1866.7 MHz
Memory Devices: 2
Video Chipset: Intel Iris Plus Graphics 940
Built-in Monitor: TV080WUM-NL0, 800x1280 resolution, MIPI Interface, from Boe Technology
Touch Screen: GoodixTouchDriver Device
Touch Pad: I2C HID Device
Audio Adapter: RealTek ALC269
Wireless Adapter: Intel(R) Wi-Fi 6 AX200 160MHz
Ethernet Adapter: RealTek Semiconductor RTL8168/8111 PCI-E Gigabit Ethernet NIC
Bluetooth Device: Intel Bluetooth Device
Battery: SR Real Battery - Intel SR 1 - 11.540 V / 57000 mWh
- 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.
- 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.
- Touchpad & touchscreen 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. 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.
- 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.
- HDMI port is not working
- HDMI audio is not working
Note: We are testing under BIOS version 1.11
- 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
- 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
