Awesome

WARNING

This repo is not maintained anymore, if you want to maintain it, please send me an mail. I no longer have this laptop.

Important

This repo has a lot of things specific to my laptop, for example all the ACPI tables. It should work in a identic computer, but maybe it won't.

Instructions

You must add your own serialnumber. I recommend GenSMBIOS. Remember to use MacBookPro14,1.

Use this a a starting point, this is no replacement of your own research, trial and error.

Remove kexts asociated with BCM94352Z(DW1560) if you do not have installed one, and do a OCSnapshot in ProperTree to remove them from config.plist.

Important: You MUST remove the wifi card from the motherboard, fail to do so will result in bizarre kernel panics during installation, after that you can reinstall again the card.

What is working

Completely supported

Audio

Audio on speakers and headphones works as intended.

CPU

XCPM power management is native supported. HWP is fully enabled as well. Added cpufriend for more energy savings.

Wi-Fi & Bluetooth

This laptop comes with an Intel WiFi + Bluetooth combo so I replaced mine with BCM94352Z (DM1560). Airport, Handoff are working correctly.

Important: If you have an Intel card, remove BCM-related kexts, rescan with ProperTree and start from there.

Camera

Camera is functioning normally.

USB

USB ports are working as expected.

Use USBInject-All.kext then with Hackintool disable all unused ports and generate a USBPorts.kext

Ethernet

Functioning normally.

Display and External Monitors

Working fine with hardware acceleration. External monitors work fine with HDMI or VGA.

Battery

Detected and correct values.

Sensors

Fan Speed, CPU temp and voltage.

Touchpad

Functioning with multigestures.

Partially working

Keyboard

Brightness keys not working. Also strange behavior sometimes after waking up, see Sleep.

Sleep and Wake

Sometimes weird behavior happens. Example, if a key if pressed when the laptop is waking up from sleep, the keyboard will stop responding, and the key pressed will repeat indefinitely in the password field, the touchpad also dies.

A workaround i've found is when the laptop wakes from sleep, do not press any key inmediately. Wait 5-10 seconds then start typing, that works for me, but sometimes the touchpad just quits anyway.

Not working

Others

Internal SD card Reader

Additional info, quirks, findings, etc

CtlnaAHCIPort is absolutely necesary to Big Sur. Using MinKernel this kext only loads in BirSur

AirPortBrcm4360 only will load in Catalina (using MaxKernel = 19.9.9). This kext makes Big Sur unable to boot.

When updating your config.plist, in order to use VoodooI2C without issues, delete VoodooInput.kext from VoodooPS2Controller.kext/Contents/PlugIns/.

You can change the laptop screen with a Latitude e7250 1080p ips. I don't have the exact screen model though.
