Lenovo Ideapad U430 - Mavericks

[RehabMan]

I followed post #422 which seems to be the same as this guide. Would it be necessary to reinstall the whole thing again?

The trackpad will work if you follow the guide (assuming your laptop has a Synaptics trackpad).

I would recommend you follow the official guide I already linked.

I did a complete reinstall of yosemite following the official guide. Trackpad is still not detected.

Your laptop does not have Synaptics. It has ELAN. You need to search for a ps2 driver for ELAN.

Thanks RehabMan! That was it. I used EmlyDinesh's kext and the touchpad works now. Thanks again for the fast replies and the help.

Was this after the update to 10.10.2 (and did the update seem to affect any kexts)?

The main problem with 10.10.2 was direct support for HD4400 mobile went away...

If you follow the guide, you should have no issue: http://www.tonymacx86.com/yosemite-...ideapad-u330-u430-u530-using-clover-uefi.html
