Hay, I tried out VoodooI2C and it didn't work. The dev said my laptop doesn't have I2C trackpad as my IOREG or DSDT didn't show / write about I2C device like TPD0, ETPD or PNP0C50.

So my trackpad is indeed PS2, but seems to be unsupported by VoodooPS2. Is there any fix for this?

Check in Windows (Device Manager) to be certain you understand how your trackpad is connected.

Here's what Device manager says, but I can't understand it well enough!

And here is what the Synaptics HID looks like

Is my trackpad connected via USB? i.e. neither PS2 not I2C??

It is USB.
I think it is, but I can't seem to find any guides on how to get USB track pads to work. Is it possible? Can you link me to any guide? Google search isn't helping too :/

Would require a custom driver.
I've heard that I2C kexts have some support for USB. You should read about it.

@RehabMan, can you tell me whether this guide will work with Mojave, I am currently using ApplePS2SmartTouchpad that identifies the trackpad but god its awful to use. Touches are sometimes registered twice, drag and drop is awful and additional gestures just doesn't work. If this guide does not apply to my laptop for Mojave, can you please guide me to the one that would be valid?

Regards
