ThinkPad T440 - OpenCore 0.6.2 Configuration

My ThinkPad T440 Configuration Using OpenCore to boot macOS Catalina. (Confirmed working for 10.15.7)

SMBIOS is classed as a MacBook Air (13 Inch, Mid-2013) otherwise known as the MacBookAir6,2

THIS THREAD IS NO LONGER BEING UPDATED, I DO NOT OWN THIS LAPTOP ANYMORE.

!! Notice !!

This configuration works for my T440, I'm not saying it will work for everyone but these are all the files and changes I had to do to make successful boots.

I have also gone ahead and removed my Serial Number, MLB and SystemUUID, you will have to fill these in yourself.

If you encounter any problems with this, leave it to issues or please push appropriate confirmed working fixes, thanks.

So what works?

• Intel HD 4400 Graphics QE/CI
• USB Ports
• Intel Ethernet
• Audio (All Inputs & Outputs with combojack)
• Sleep and Wake
• Mini DisplayPort and Mini DisplayPort Audio
• VGA (Although I don't know about other T440's, mine just seems to work)
• CPU and IGPU Power Management
• Battery Status
• Brightness
• Function Keys (Fn) - Read Below about ThinkPadAssistant
• ClickPad and TrackPad
• Integrated Camera

My Audio Isn't working out of the box, What do I do?

• Download ALCPluginFix
• Extracted ALCPlugFix folder into Desktop.
• Open Terminal and enter the following commands 1by1:

    sudo spctl --master-disable
    sudo mkdir /usr/local/bin/
    cd desktop/ALCPlugFix
    ./install.sh

Wireless?

While Intel Wireless Network is presumed to now work with a Patch from OpenIntelWireless, I have opted for a Broadcom DW1560 on BIOS Revision 2.36.

Handoff with Bluetooth with the DW1560 works perfectly and had.. well a little trouble communicating with my iPhone. (Read below)

Known Issues (Results may vary):

• Docking Station Audio Jack has no input support, only output because we can't use two inputs as LineIn.
• SD Card Reader (At least for me) when a card is inserted will send you into a loop of Kernel Panics until removed.
• Kernel Panic into an Instant Reboot when attempting sleep, restart or Shutdown while External Display connected on one of the Docking Station Video Ports (DisplayPort, DVI, VGA)
• No DisplayPort Audio when using the Docking Station DisplayPort
• Handoff Somewhat works, WiFi Password Sharing and Hotspots with iPhone's don't seem to function.

Keyboard Functions - Optional

I've just started using a tool by the name of ThinkpadAssistant which will work perfectly with this configuration, I have confirmed myself that the T440p Sample works with this, and feel like that while this isn't in my configuration it will be handy for you to have.
