Secure Boot (Optional)

1. Set Secure Boot to Setup Mode. Secure Boot should be reported as off by UEFI main tab
2. Create FAT32 formatted USB
3. Create EFI folder in the root of the newly formatted flash drive and move there content of SecureBoot/KeyTool
4. Boot flash drive via F12 boot menu
5. Choose Edit keys

6. Start by replacing Signature Database. Select .auth file

7. Do the same for Key Exchange Keys Database (KEK) and Platform Key (PK) in this order
8. Exit and shutdown your machine
9. Boot into the UEFI settings and check if Secure Boot is reported as on
10. Boot you favorite OS with Secure Boot enabled

! Still quite experimental

Post-Install

Colour banding

If you encounter some serious colour banding issues ( Keep in mind that T480 1080p stock panel colour accuracy is not really good, cca 50-60% sRGB), your only solution is to replace GPU properties as bellow or replace the stock panel with one from T490 (400 nits, Low power).

<key>AAPL,ig-platform-id</key>
<data>AAAWGQ==</data>
<key>device-id</key>
<data>FhkAAA==</data>
</dict>

Do not use these any additional boot arguments! Get custom WhateverGreen version instead from Other folder

You can check your screen in gradient test here or just by simple look at Launchpad background.

Generate your own SMBIOS

GenSMBIOS

• MacBookPro14,1

• MacBookPro15,2

CPUFriend power management

Generate CPUFriendDataProvider for your machine here or use at your own risk files provided in the Other folder.

VoltageShift undervolt

It is possible to use VoltageShift directly from the EFI folder instead of disabling SIP. You need to use specific version provided in the Other folder.

! If you want to use this feature, enable it in config.plist

Android USB Tethering | HoRNDIS

Important: Mac computers can't tether with Android.

I don't think so Google.

1. Using a USB cable, connect your phone to the other device. A "Connected as a…" notification shows at the top of the screen.
2. Open your phone's Settings app.
3. Tap Network & internet Hotspot & tethering.
4. Turn on USB tethering.

You should see new Ethernet connection in the network settings. Works with USB Type C and USB A.

! If you want to use this feature, enable it in config.plist

Problems with recreating new en device every time are now solved on latest macOS versions with patched version of this kext. If it does not work for you, revert to official version.

Status

What's working ✅

• Battery percentage

• Bluetooth - Intel Wireless-AC 8265 (0x0A2B) (Not maintained in repo)

• Broadcom Bluetooth - All works! (native)

• Boot chime

• Boot menu OpenCanopy

• CPU power management / performance Now on par with Windows without XTU undervolt.

• FireVault 2 No config.plist changes needed

• GPU UHD 620 hardware acceleration / performance

• HDMI Closed lid. With audio.

• iMessage, FaceTime, App Store, iTunes Store. Generate your own SMBIOS

• Intel I219V Ethernet port Full 1 Gbps speeds and external eithernet adapter next to TB port also works

• Keyboard Volume and brightness hotkeys. Another media keys with YogaSMC.

• Microphone With keyboard switch using YogaSMC.

• Realtek® ALC3287 ("ALC257") Audio

• SD card reader Fortunately, USB connected.

• Sidecar wired Works with 15,2 SMBIOS. Wireless with Broadcom Card

• Sleep/Wake Hibernatemode 25 for the best results.

• Thunderbolt 40 Gbps after start and 10 Gbps after sleep wake

• TouchPad 1-5 fingers swipe works. Emulate force touch using longer and more voluminous touch.

• TrackPoint Works perfectly. Just like on Windows or Linux.

• USB Ports USB Map is different for devices with Windows Hello camera.

• Web camera Works well with MacOS with no bugs

• Wifi - Intel Wireless-AC 8265 works using heliport and itlwm with big sur

• Broadcom Wifi - Native broadcom cards work perfectly with all features available wirelessly too. Legacy

• DRM Widevine, validated on Firefox 82. WhateverGreen's DRM is broken on Big Sur

What's not working ⚠️

• Intel WIFI Most of it works but MIGHT still be buggy (Not Maintained in this repo). If any bugs, check the dortainia guides regarding intel wifi. (Broadcom native is stable)

• Fingerprint reader There is finally after many years working driver for Linux (python-validity), don't expect macOS driver any time soon. (Able to see it as a synaptics usb device and can be used on an ubuntu vm on macos)

• Continuity(Intel Cards) If you want to use this feature, buy a compatible Broadcom card!(Latest release only has drivers for Broadcom cards)
