Hi All,

I've a near complete Thinkpad X270 running Mojave 10.14.6 (18G103).

However, no matter what I try, I cannot seem to get the trackpad working.

I've looked all over for a solution but it seems there are either not many users with X270 posts on forums, older Lenovo X series voodoo.kexts don't work, or everyone is smarter than me and has their X270's working perfectly without problems.

My X270 trackpad is Synaptics PS2 with the three buttons.

I'm using the latest version of VoodooPS2Controller.kext (1008) from Rehabman's repo.

I've patched my DSDT for battery (this appears to be a known dependency for Trackpad functionality) and have full visibility of the Trackpad functions in System Preferences. Keyboard is working without issue (minus Fkey functions remapped via Karabiner).

Peculiarly, the Trackpad has come to life on some boots (approx 1 in 20) using Rehabman's VoodooPS2Controller. On this occasion all buttons are effectively 'right click' and some of the more simple gestures work.

If anyone has any insight as to how I can fix the trackpad, please let me know. I'm willing to put in the effort and learn.

Cheers,
