I did some huge improvements,mistake fixes,removed a bunch of unecessary code,added what was missing, etc.
Will upload changes and guides for:
L440,L450,T440,T440S,T440P,T450,T540P,x240 & Lenovo B570e.
Most of the mentioned guides and changes will be uploaded this weekend “if something else doesn’t change my plans”,except T540p,T440S,T450 that they will need more testing to be done.
Although it might be better to add them too since users might see the guides and i get more people to test that way.

- Fixed those acpi mistakes like imei/smbus/etc.
- Fixed Audio, Patched from scratch (all inputs and outputs working)
- Mapped all Keyboard buttons (each button should work now).
- new config.plist files, to match @RehabMan Clover Bootloader fork.

For FAN reading that should be a piece of cake for all the other laptops that i don't own except my L440 and my B570e which they don't have multiple byte EC Fields and FAN reading Offset is 8-bit code which will require me a lot more time to create a formula to multiply to show correct RPM.

About iTunes problem with Black Screen make sure you are running latest version of these 3kexts:
-Lilu.kext
-Shiki.kext
-IntelGraphicsFixUp.kext
 
Hey, I followed this guide, but I'm having a bit of a problem. After using my T440p for a day or so, my trackpad stops working -- left, middle, and right click stop working, and the trackpad stops tracking. The trackpoint continues to move the cursor, but without the ability to click, it becomes quite useless. Oddly, scrolling with the middle button and trackpoint seems to still work, as well as dragging with the left click button.

The only solutions are to either restart the computer, or to plug and unplug a wired mouse (this only works if I have it setup to ignore the trackpad upon mouse hookup in accessibility. If this is off, this trick does not seem to work).

I have a Synaptics T460 three button trackpad installed, and am running 10.13.2. I am, of course, also running the TLUCK fork of VoodooPS2.

Any advice on how to fix this would be greatly appreciated. ^_^

Might be due to dual GPU.
There is no code in SSDT-T440P.aml to disable the Nvidia.

I follow Snikk's guide and use the file... Sorry I don't know how to disable the Nvidia....
 
Sorry for the long delay guys, my external HDD where i used to store all my data got corrupted and lost track of all my data.
With a few recovery software i managed to restore at least all my photos, but rest of the stuff is gone... anyway

Tomorrow hopefully if nothing else happens i will update the guide, new features/changes/fixes:

- Fully working Audio (Patched from scratch on my own, all inputs and outputs ; after wake/sleep working flawless so far).
- New Keyboard Map (All FN Buttons are supposed to work, including "PrtSc" - Print screen and Fn+F11)
- New config.plist to cover new Changes & Patching (from Rehabman fork of Clover Bootloader).
- Fixed a lot of ACPi Errors (removed unnecessary/wrong patches ; added missing stuff).
- Added SMCD Device (Fan RPM reading code and CPU Heatsink Temperature should show on HWMonitor.app correctly).
- Added install_config.plist (for installation & especially users that have T440P with Nvidia Graphics to be able to install macOS).
- Disabled Nvidia Discrete GPU for T440P with Discrete Graphics.


@RehabMan :
Seems that the stuff on config.plist is the same to bypass installation issues with discrete Nvidia GPU but since i don't own the laptop i wanted to ask before i post the update to the guide:
Are the 3: "AddProperties" Nvidia patches + Inject Nvidia enough to be able to proceed with Installation or a SSDT-NvidiaSpoof is also needed for that ?.

Thank you so much for your work Sniki!...I take my hat off to you!
My 440p works flawless with the lastest features/changes/fixes you uploaded the last time.
I´m waiting impatienly the new files you´re going to upload today (or next days).
Practically, the hack is now perfect!
Thank you again!

Should be assuming Clover recognizes the Nvidia device and injects (Graphics/Inject/NVidia=true).
Doesn't seem to work with certain Nvidia devices (so probably a Clover problem), in which case SSDT-DiscreteSpoof.aml needs to be used instead.
In other words, YMMV.
