What works

Sleep / Wake
Wifi and Bluetooth (Built-in Intel 7265 or 7260 cards with Heliport + itlwm.kext) Airportitlwm.kext is not recommended, it causes issues with Trackpad after wake from sleep
AirPort Extreme (Broadcom BCM94360CSAX & NGFF A/E Adapter) Recommended Upgrade to get native WiFi & Bluetooth
Handoff, Continuity, AirDrop
iMessage, FaceTime, App Store, iTunes Store (Change Config.plist -> PlatformInfo -> Generic -> MLB and SystemSerialNumber)
Ethernet
Onboard audio (Use alc_fix to fix unworking jack after replug )
USB 2.0 / USB 3.0
Dual Batteries
Touchpad
Trackpoint
miniDP
SD Card Reader (Thanks to @willmav5000)
Use one-key-hidpi to enable HiDPI
If you are using a usb mouse with side buttons, you can spoof apple usb mouse by change the pid and vid in AnyAppleUSBMouse.kext/Info.plist and enable it in config.plist.

What doesn't work

VGA
Sidecar (Wired Sidecar works but only in Macbook9,1 SMBIOS, which has bad battery life, you can choose what you want)
With the IntelBluetoothFirmware.kext and itlwm.kext enabled Bluetooth headphones only work when you are not connected to any wifi network or turn off wifi. This is a known issue with 7265 and 7260 cards. You can get 8x series cards to fix this or buy the recomended cards (DW1820A 00JT494 or Broadcom BCM94360CSAX)

Note: If you need to edit config.plist, don't use OpenCore configurator or Clover configurator, use PlistEdit pro (Included in Utilities) or Xcode.
