This post is not meant to be a guide. Instead, I hope this thread is able to gather all VoodooI2C kext users to share their knowledge and new users to be able to activate their I2C track pads. This write up is a simplified version of the original to benefit new hackintoshers. It is always advised to read the actual documentation by the developer in case I had missed out important key points.

Another note, users are urged to participate in developer's gitter chat for better support or report major issues. And you are expected to had done the preliminary steps mentioned below. I would like to point out again that this is not an official VoodooI2C help page.

IMPORTANT 1: Ensure 'Disable built-in trackpad when...' is disabled within accessibility preferencesThis setting usually appears when your I2C device is fully detected in ioreg app but trackpad still do not function. Or, trackpad do not function when a USB mouse is connected. So, if you have not got your trackpad working, then move on to the next steps.

IMPORTANT 2: Enable advanced option for trackpad in bios if option is available.

IMPORTANT 3: Delete Trackpad and Mouse plugin from within VoodooPS2Controller kext to avoid conflict. We only need the keyboard plugin. Except in certain scenarios where touch screen is an I2C device and trackpad is a PS2, then do not remove the plugin.

IMPORTANT 4: Disable _DSM to XDSM/ZDSM patches. This is one of the common mistakes found from most new users. DO NOT USE THESE PATCHES.

IMPORTANT 5: Disable Apple's I2C Kext to patch by adding Coolstar's patch below

Include Coolstar's patch in Clover's kext to patch.
<key>KextsToPatch</key>
	<array>          
		<dict>
			<key>Comment</key>
			<string>Prevent Apple I2C kexts from attaching to I2C controllers, credit CoolStar</string>

</dict>
Or, if you are using plist editor/ xcode/ clover configurator. Refer to the the screenshot below.

IMPORTANT 6: Update to the latest BIOS version if available. Some machines had been reported to have working/ better trackpad experience after a BIOS update.

IMPORTANT 7: Never.

NEVER INSTALL KEXTS in System/Library/Extension (S/L/E)!

For the ease of troubleshooting, keep your kexts in Clover/Kexts/Other and that works majority of the time!

If you have had installed kexts using kext installer app or similar, REMOVE the installed kexts in S/L/E (or L/E) NOW!! Keep kexts at Clover/Kexts/Other only.

OPTIONAL:

In the past, track pad tends to be disabled after every OS update and a simple rebuild of kext cache then rebooting will solve that minor issue. However, adding these in config.plist force loads trackpad without rebuilding kext cache (I'd recommend to still do a rebuild, anyway )
<key>ForceKextsToLoad</key>
<array>
<string>\System\Library\Extensions\IOGraphicsFamily.kext</string>
</array>
Additional Info :

Some users might want to check that the trackpad settings are ticked or configured. In some cases, trackpad will only work like a normal mouse if the settings are not chosen. If you do not have these trackpad settings appear, it is likely you do not have a working battery status or you are using the wrong voodooI2C satellite kext or you did not choose advance setting for trackpad in BIOS.

This is the official VoodooI2C gitter chat where you can ask the dev for comprehensive support

https://gitter.im/alexandred/VoodooI2C

It is also a known issue (at least in my knowledge at this point of writing) that certain version of kexts are not compatible with some devices and may involve some trial and error of different releases of kexts.

*Note: You must not have any other I2C kexts installed except for VoodooI2C kexts.

The following device classes are fully supported:

- I2C-HID devices

- ELAN devices

- FTE devices

Before posting for help and attaching send me files, new users are advised to take the below steps which are crucial. These preliminary steps are also outlined by the original dev in his wiki guide.

How to provide debug files

An easy way to provide debugging files is to run to run this app http://Olarila.com/files/Utils/RunMe.app.zip.

Run the app and do not do anything until the app has finished collecting all necessary files. Then upload the sendme folder created on desktop.

Also, before using Run_me app, make sure you boot from your SSD/HDD clover and NOT from USB bootable disk!

VoodooI2C Dev guide can be read HERE.

Lets Begin!

Basically, we are required to know these 3 main items

1. ACPI ID

2. APIC Pin Number

3. Ensure I2C Serial bus name are correctly labelled in DSDT.

Below are the steps on how to achieve the 3 criteria mentioned above.

Step 1 - Identify ACPI ID or GPIO pinning

If you have windows installed in another partition or drive, use Windows Device Manager to locate your device's ACPI ID like shown in the picture below.

https://imgur.com/FIJPN8P

In this example, the ACPI ID is TPL0

If you do not have windows installed, dont worry, continue to follow the step below

Step 2. Determining your interrupt pinning situation/ APIC pin number

a. First compile your DSDT by simply pressing F4 at clover boot. The file will be available at Clover/ACPI/Origin

b. Patch your DSDT with windows patch script below using MaciASL
into_all method code_regex If\s+\([\\]?_OSI\s+\(\"Windows\s2015\"\)\) replace_matched begin If(LOr(_OSI("Darwin"),_OSI("Windows 2015"))) end;
c. Place the patched DSDT into your clover/ACPI/patched folder. Reboot.

d. Use IOREG to find your ACPI ID like below picture

https://imgur.com/arLFTF3

In this example, the ACPI ID is TPD1.

Click on IOInterruptSpecifiers to reveal the hexadecimal APIC pin number. In this example the APIC pin number is 0x33. If we convert 0x33 to decimal, it will be 51.

If your APIC pin number is equal or less than 47, you can proceed to install kexts.

If you do not have IOInterruptSpecifiers, you can also proceed to install kexts.

Download latest kexts HERE

Always install 3rd party kexts in Clover/kexts/other. DO NOT install kexts in S/L/E! NEVER!

Step 3. Ensure I2C Serial bus name is correctly labelled

You will also need to make sure that your I2C Serial Bus Name is correctly labelled. Search for your device ACPI ID in your DSDT until you reach its device entry, you should be able to find a Name called SBFB. If you cannot find it, you may find something that looks like this instead:
Method (_CRS, 0, Serialized)  // _CRS: Current Resource Settings
               {
                   Name (SBFI, ResourceTemplate ()
                   {
                       I2cSerialBusV2 (0x0015, ControllerInitiated, 0x00061A80,
                           AddressingMode7Bit, "\\_SB.PCI0.I2C1",
                           0x00, ResourceConsumer, , Exclusive,
                           )
                       Interrupt (ResourceConsumer, Level, ActiveLow, Exclusive, ,, )
                       {
                           0x0000006D,
                       }
                   })
                   Return (SBFI)
               }
In this case, rename SBFI to SBFB and remove the following from it:
Interrupt (ResourceConsumer, Level, ActiveLow, Exclusive, ,, )
   {
       0x0000006D,
   }
But, what if your APIC pin number is greater than 47?

to be continued..

Note: All guide and thanks to the hardwork of original developer whom can be contacted at https://gitter.im/alexandred/VoodooI2C

My ACPI pin no. is ETPD@1 can your method works for me??

onemanosx · November 21, 2019

[ref]nikhilrathore_1999[/ref], ETPD@1 is not a PIN number but instead it is an ACPI ID.

This guide is generic for supported I2C trackpad or touchscreen devices

Check with preference settings.

Otherwise, you can try polling mode. ASUS laptops are known to have buggy GPI0 when running in interrupt mode.

No idea. How often does this happen? Also, check if you have a new bios update.

Hi,

I tried to come here after realizing my trackpad was failing with clicks, or holding the click when it shouldn't

I did the whole process, but it happened was my trackpad stop working =c

updated the pin in SBFG (set 0x3F), and I'm returning in _CRS -> Return (ConcatenateResTemplate (SBFB, SBFG))

This is my Runme: https://drive.google.com/open?id=1_RBge ... opdoeUNd-r

onemanosx · November 25, 2019

[ref]luccasoli[/ref], Your DSDT has native GPI0 pin. Therefore, there is no need to specify a pin manually.

Give this a go and feedback with a new sendme file.

[ref]onemanosx[/ref], Now the clicks work great, thanks!

To be perfect, I think it just needs to be recognized as an apple trackpad (with those gestures), but thanks for the help! : D

Hello.

I have a nice Lenovo 320-15IKB with 8250u CPU and a i2c Synaptics Trackpad.

Its a SYNA2B3C.

I have almost everything running but no Trackpad. Its working but it move and jumping.

I have generate DSDT.aml with Clover F4 and add Windows 10 Patch and GPIO Patch.

Please can someone help me.

So the GPIO Pin must be 0x3F I I understand the Tutorial.

57 = 63 = Dezimal to HexDecimal = 0x3F

But the Trackpad is not working properly

Please can someone help me.
