HP Elite X2 G1 Hackintosh

THIS REPO IS STILL WORK IN PROGRESS

Hardware Specs:

CPU:     Intel M7 6Y75
RAM:     8GB 1866MHz LPDDR3
GPU:     HD 515
AUDIO:   CX20724
Touch:   Wacom HID Based Display(WCOM4814)

What's working

• USB/C Hot-plug
• USB-C DP/HDMI Output
• Mic, speakers and headphones
• CPU Power Management
• HiDPI
• Touchscreen and pen
  • Using the [Wacom Bamboo Ink Pen] (https://www.wacom.com/en-us/products/stylus/bamboo-ink), all Wacom AES based pens should work with the HP Elite X2 G1 and G2

What's not working

• Battery cycle and temps
• Alps kext unloading
  • Fixed if installed in L/E(sadly)
• VoodooI2C working intermediately
  • Related to ACPI power states
• DRM
  • No iGPU has working DRM

ACPI

For those curious, I've also provided an ACPI dump of my laptop(BIOS ver. 1.48 Rev.A):

• Firmware Dumps
• Custom SSDTs

Required SSDTs:

SSDT	ACPI Patches	Comments
SSDT-BAT	A lot	Fixes Battery Readouts
SSDT-EC-USBX	N/A	Creates a fake EC and adds USB Power Properties
SSDT-HP-FixLidSleep	N/A	Fixes e005 keyboard spam
SSDT-PLUG	N/A	Adds plugin-type to \_PR.CPU0, allows XCPM to load
SSDT-PNLF	N/A	Adds Backlight control support
SSDT-PTS	_PTS to XPTS	Reroutes USB Shutdown calls
SSDT-SBUS-MCHC	N/A	Allows AppleSMBus and co to load
SSDT-SLPB	N/A	Fixes Sleep button support
SSDT-TBHP	N/A	Fixes USB-C Hot-plug
SSDT-TPL0	PS0/PS3 to XPS0/XPS3	Attempts to fix I2C touchscreen *

• Need to look into proper _PS0/_PS3 fixes for I2C

For a full list of ACPI patches, see here: patches.plist

Removing XOSI Renames:

Thanks to DhiankG, XOSI renames are no longer needed. Instead only needing the following patch:

Comment | String |  Enable Touchscreen in macOS
Find    |  Data  |  95 4F 53 59 53 0B DC 07
Replace |  Data  |  95 4F 53 59 53 0B 00 00

Kexts

Hardware specific kexts:

• VoodooI2C
• VoodooI2CHID
• AlpsT4USB
  • A prebuilt for the latest(7faceb9) can be found here: AlpsT4USB.kext

Configuration Specifics

DeviceProperties:

• PciRoot(0x0)/Pci(0x1F,0x3)
  • layout-id | Data | 03000000
• PciRoot(0x0)/Pci(0x2,0x0)
  • APPL,ig-platform-id | Data | 00001E19
    • Apple uses 03001E19 on lower end MacBooks(M3)
    • M7 failed to boot with this so try either and see which works best for you

Kernel:

• Quirks:
  • AppleCpuPmCfgLock set to True
  • AppleCpuPmCfgLock set to True

PlatformInfo:

• Generic -> SystemProductName:
  • MacBook9,1

Miscellaneous Faixes

HiDPI:

• See here: HiDPI Fix-up

TO-DO

Current issues:

• I2C Screen sometimes gets into bad state even with XPS0/XPS3 reroutes
  • Need to look into implementing proper power states
  • Reboots between Mojave and catalina fix the issue, not really a fix but works for now
• IOUSBHost crashing in Catalina
  • Intel Bluetooth being trash, waiting for BCM94360NG to arrive
• Alps kext unloads when keyboard cover disconnects(about 2 min after)
  • Midi's G2 doesn't have this issue, gonna blame G1 + BlackMac not using a G1
  • Installing into L/E works(Sadly)
• Using RTC ACPI Patch, need to find correct offset to block with RTCMemoryFixup
  • As of BIOS ver.01.45, the main region is DF-E0
  • Wake from deep sleep will cause a restart with RTC error, likely multiple regions need to be fixed
• Look into cycle count and temperature in SSDT-BAT
  • zprood's cycle count hack
