v0.6-beta1

Hello, this release see's many changes.

• make the switch from VoodooHDA to AppleALC for audio *refer back to main guide for instructions on fixing headphone jack noise.
• add T450 Synaptics trackpad support, confirmed all gestures working with 3 buttons and keyboard trackpoint working.
• Update to OpenCore 0.7.6
• Update FeatureUnlock.kext to 1.0.4 (this kext remains disabled as previously caused stability issues, still included in package for those who wish to try the newest version, i have not tested stability on new release but believe it may work)
• Update Lilu to 1.5.8
• Update Realtek CardReaderFriend to 1.0.1
• Update VirtualSMC and components to 1.2.8
• Update Voltage Shift to 1.25
• Reboot Tool added to picker menu so that people who are using external monitors with a mouse which doesnt connect can also reboot, i suggest trying to 2 buttons at the bottom of the picker with your built in trackpad to reboot or shut down, it works :)

i suggest going over the main guide again as it has been revised with more tips to help your system run better.

as always, don't forget to edit the EFI to add your own serial numbers.

Enjoy, thanks for the continued support.

v0.5-beta2

This release is is a quick fix for all the random freezing issues which were causes by feature unlock kext. the kext is still in the build but disabled, it will be tested going forward and if starts working on monteray for T440P i will start releasing 2 builds, i can not confirm this works on monteray as i havnt tried the upgrade yet but if anyone wants to let me know that would be great.

Changelog

• Update to OpenCore 0.7.5
• Update to Lilu 1.5.7
• Update to HibernationFixup 1.4.5
• Update to VirtualSMC 1.2.7
• Update to WhateverGreen 1.5.5
• Update to VoodooPS2Controller 2.2.7

IMPORTANT NOTE
this build uses VoodooHDA, VoodooHDA does not run at the bootloader level on 11.4 and up (possibly lower), and must be loaded into the L/E folder, follow below for instructions on how to fix.

first you will need to ensure SIP is not enabled, to check it run the "csrutil status" command in terminal and this is what you want

"Connor@Connors-MBP ~ % csrutil status
System Integrity Protection status: unknown (Custom Configuration).

Configuration:
Apple Internal: disabled
Kext Signing: disabled
Filesystem Protections: disabled
Debugging Restrictions: enabled
DTrace Restrictions: enabled
NVRAM Protections: enabled
BaseSystem Verification: enabled

This is an unsupported configuration, likely to break in the future and leave your machine in an unknown state."

IF YOU DONT GET THIS RESULT, AND SIP IS ENABLED, IT WONT WORK, IF SIP IS FULLY DISABLED IT WILL STILL WORK.

IF YOUR SIP IS ENABLED, SELECT THE CLEAR NVRAM OPTION AT OPENCORE BOOTLOADER AND IT WILL FIX IT.

once you have SIP setup properly download VoodooHDA here - https://sourceforge.net/projects/voodoohda/files/

place the kext on your desktop and run this command replacing where it sais USER with your username

"sudo cp -R /Users/Connor/USER/VoodooHDA.kext /Library/Extensions"

once done you should be promted a security prompt to allow VoodooHDA, allow it and reboot.

if you manually drag it, it will not work.

as always, don't forget to edit the EFI to add your own serial numbers.

Enjoy, thanks for the continued support.

this build drops AppleALC support, i highly suggest using VoodooHDA for Audio on T440P. However VoodooHDA does not run at the bootloader level on 11.4, and must be loaded into the L/E folder, follow below for instructions on how to fix.

first you will need to ensure SIP is not enabled, to check it run the "csrutil status" command in terminal and this is what you want

1. OpenCore 0.6.8

2. Switch from FakeSMC to Virtual SMC

3. VoltageShift is working with SIP enabled :D

4. YogaSMC is working for fan control

please review the main release page for documentation https://github.com/VinylNerd/ThinkPad-T440P-OpenCore

enjoy! :)

v0.2-beta1

fixed up a few things, if you do not use dock and wish to enable wake from sleep with usb make sure to enable this acpi patch shown here

if using opencore configurator one can go to boot->misc->laucher option, and set to full, after 1 restart opencore should get added to your bios boot menu, and u are free to remove the bootfolder from opencore to boot without it, the bios will point directly to the opencore.efi and boot from it :)

everything else working great, i updated to 11.2.3 with the boot folder in the EFI and left everything as is, flawless update.

issues:

1. Audio over DP to HDMI coverter, need to do research and testing
2. SD card not working
3. audio seems a little quiet for me, gonna try to find a better version of VoodooHDA as was on 2.9.2 before and i think it was better, this build as 2.9.6

thanks and enjoy, any issues or questions please let me know
