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

• This guide is not for models with Haswell 4th gen CPU
• The patched ACPI files were first created by EchoEspirit. Then racka98 Tweaked couple of things and fixed some errors and Released for some months to opencore 0.7.0. Later I tweaked couple of things and Updated the Release of 0.7.0 to 0.8.2.
• I will try my best to keep the repo updated with the latest kexts and OpenCore version
• This EFI works with ,MacOS Big Sur, Catalina (Need to tweak some of the things to work perfectly. -For macOS Monterey this EFI will work great as BigSur, But audio is not working Only in Monterey. Tried many ways to fix but may fix later releases. so don't expect flawless functionality
• This EFI is Configured with Big Sur in mind. If you are using it on Monterey, Catalina read the the whole guide to know where to make the necessary changes
• With every EFI update you retrieve from here please remember to go through the post install guide

This is a simple and quick summary of the online install USB creation

Windows Guide:(Works for Macos users also)

1. Download rufus
2. Select the desired flash drive or Sdcard you would like to put the installer on under the device option
3. Select non-bootable as the boot selection (REQUIRED)
4. Select FAT-32 or Large FAT-32 as the partition scheme

• For mac users

1. Launch Disk Utility
2. Select View > Show all devices at the top left
3. Select your flash drive (root usb device)and format it as MS-DOS (FAT) or FAT-32 and change guid patition table-> Master Boot Record Partiton.
4. Open up the usb partition in file explorer and delete the files created by rufus
5. Create a folder on that partiton named com.apple.recovery.boot
6. Install Python from Microsoft store or Download manually here -> python (Make sure you select add python x.x to path)
7. Download and extract the OpenCore Package
8. Select the macrecovery folder in the opencorepkg folder at /Utilities/macrecovery/
9. Click on home > copy path at the top of file explorer

11. Run the command macrecovery.py -b Mac-42FD25EABCABB274 -m 00000000000000000 download
12. This will put some files in the macrecovery folder but we only need BaseSystem.dmg and BaseSystem.chunklist (takes approx. 600mb to 800mb internet)for Downloading the Macos installer.
13. Paste both of those files in the com.apple.recovery.boot folder in your flash drive partiton
14. Download the latest EFI created here

Once you have verifed that your machine boots properly without any issues as described in the "What Works section", proceed to do the following

In Config.plist, navigate to NVRAM -> Add -> 7C436110-AB2A-4BBB-A880-FE41995C9F82 -> boot-args and give a single space and add the -v argument

In the Config.plist, You can disable the boot picker screen so that you boot straight to th Apple logo by setting under Misc -> Boot -> ShowPicker False (NO) Note: you can still see the boot picker with ShowPicker set to no/false by spamming Esc before the apple logo is displayed during boot.

Using YogaSMC you can gain this functionality back. Install the YogaSMC App-Release from here. Install it then open it to set it up.

You can Disable IntelBluetoothFirmware.kext & IntelBluetoothInjector.kext to be able to Boot faster those kexts in config.plist This is not done by default to bluetooth working. For those on macOS Monterey do not enable these kexts because the system will not boot

Follow this Opencore guide to set up serial number and the accompanying info to get iServices

If you want to get wired sidecar working, in Config.plist change the string in Platforminfo > Generic> SystemProductName to MacBook9,1 (note: this causes the battery to drain faster)

When you connect headphones/earbuds via the headphone jack you will hear static noise. To fix this install alc_fix_new located in Utilities folder of this Relese Efi folder.(This may not work 100%) Tip: To fix it, plug the headphones and close the lid and open. This may fix the static noise. This issue may fix later on Relases.
