This repo contains the installation guide and EFI files required to get a perfectly functional Catalina 10.15.7 hackintosh on your T450 or T450s since they share the same hardware. Everything is stable and functional as described in this Readme.

A few worthy mentions about this repo**:

This guide is not for models with Haswell 4th gen CPU
The EFI folder and the patched ACPI were first created by EchoEspirit and futher optimized by i3p9. I tweaked a couple of things and fixed some errors that were happening on T450 + added Intel WiFi drivers from Openintelwireless
I will try my best to keep the repo updated with the latest kexts and Opencore version
This EFI works with Big Sur Beta 9 but compatibility with future versions is not guaranteed until i update the kexts and Opencore version that will support the latest version of Big Sur

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.
