To use a MacBook Pro's touchpad as a replacement for a normal touchpad on a Hackintosh without needing special extensions, you'll need to repurpose the trackpad's SPI interface and convert it to USB. This can be done using a CY8C24794 chip, which serves as an SPI to USB converter. https://winpkrapk.com/

After lots of hours I managed to succeed. Both the keyboard and trackpad (from a 13" MacBook Pro 2011) work flawlessly in MacOS and Linux. Works ok in my BIOS and in Windows 10 (no gestures, "just" like a mouse). But unfortunately the trackpad (keyboard works fine) doesn't work in Android at all. It just appears dead.

The driver (Apple USB BCM5974 (Macbook Air and Penryn Macbook Pro) multitouch driver) is apparently included in Android since 2013 and offers functionality for exactly my trackpad model.

The issue is: 

Samsung Galaxy S8 (Android 10): Trackpad not working

Lenovo P11 Pro (Android 11): Trackpad not working

Desktop PC, booting Android-x86 from USB stick: Trackpad not working

Same Android-x86 inside a virtual machine: Trackpad WORKING FLAWLESSLY with all gestures (which means the driver is indeed included and working).

I'm desperately looking for help, what kind of sorcery is this? :(

Does anyone have any idea.... or has anyone done such a trackpad -> usb conversion and can test it on an Android device?

Hi man, I need to tell you something, I did the same tests you did on this touchpad.  I even added an A1278 keyboard  and it worked normally on an imac 27 high siera (to activate click function on mac you need to put in macbook system and activate click function of native touchpad.)

 i also made with a board of an a1466 a simple board.  got the idea from a guy !

here for me who works with technical assistance and easy to get these parts and test. on my S8+ the brightness and volume boost functions work fine.  the touchpad doesn't work, they put it works in old versions of windows.  the bad thing is that it stops responding to commands after a while, then just unplug and plug in again.  here is a video of mine.  https://youtu.be/csA7YgNfwg0

Cheers mate. I tested a bit more. On Android_x86 for pc... if you boot Android and then plugin the keyboard/trackpad, it does not work.

If you plugin the keyboard/trackpad BEFORE booting it works (including all gestures).

But on phone/tablet, plugging it in before booting does not help :(

Man I was sure it was possible! Need to test it myself!

I'm especially asking about the keyboard because I see all the input from the trackpad and keyboard go into the CY8C24794, but I only see USB_TPAD_P and USB_TPAD_N as output. Do these two data lines include the keyboard as well?

@acccela the early 2009 C2D A1286 does in fact have the CY8C24794 and the keyboard and trackpad is connected to it.

Pro tip: get the Apple identifier like A1286 and then you need to google 2 things with that identifier: schematic and boardview. The schematic help you view the system, the boardview help you see the board. Get them find the chip in boardview and the connection in the schematic

Hi! interested in doing something similar. Disassembled a A1278 mbp hoping it would have easy USB pinouts (as i found guides doing it on the white macbook from the same era.)

It has the same finicky plastic ribbon cable with a billion etches so i figured that's useless to try and list out what's what.

It looks like you've not really removed the pad from the logic board, and wired that up instead?

Any tips? i'll be checking the logic board tomorrow and see if i can't figure something out. I really need a bluetooth/wifi connected trackpad 'cause the one on Clevo computers are just butts.

Any information you could share with me would be very much appreciated.

not really just follow the boardview and the schematic and you will do fine, isolate all components for CY8C24794 cut the board or desolder all components and resolder them. Maybe in the future I will do a proper tutorial.

I would love to see a tutorial.  I'm only sort-of grasping your instructions.  

Unfortunately my macbook pro is another model, probably late 2008/early 2009. And the pcb differs enough so i can't find CY8C24794. Tried finding a service manual but it's Apple.. And that's about as far as my knowledge and experience takes me. I don't have access to a microscope either so following traces sucks.

If i can figure out what i can source 3.3v from it should be easy, but i dunno how.

I'll hop on the project some time later i guess.

Thanks for replying btw! didn't expect an answer seeing how old the project is.

A proper tutorial for this would be awesome!

I'm pretty new to electronics and while I can do the soldering etc, I can't seem to get where exactly you put your wires and why.

Also, is it possible to use the keyboard the same way?
