Known issue. You need to replace trackpad.prefpane with version from 10.11.6

Try here.

Yes, twice in my case... (see edited post above) one was from 10.11.6 and the second time it was from 10.11.   If you can't make Sierra installer to work after reboot or you are getting an error try

Schiller, i have an e7240 which I believe has similar configs like your e7440. All works great in my 10.12.6 except left mouse clicks dont and bluetooth.  Can you help me figure out or share the kexts and I can try. thanks

 

For trackpad I use Dr. Hurt's: VoodooPS2Controller.kext.zip

 

Working:

  • 1 finger tap click
  • Both clicks (including the ones above touchpad)
  • Trackstick
  • 2 finger tap for right click
  • 2 finger scrolling
  • 3 finger gestures (like change desktop screen)
  • 4 finger gestures (hard to do for me mostly because of the trackpad size)
  • Preferences settings:

Not working or probably I don't have them configured:

  • 2 finger gestures (like previous page or show all active tabs both in safari)
  • Edges scrolling (I don't use this anyway)

 

I load it in /EFI/CLOVER/kexts/10.12/ and I haven't found problems so far, just make sure you don't have any other trackpad  kexts or duplicates in /S/L/E or /L/E and you can load the kext from any of those locations btw (just one like I said).

 

If you load any kexts from /S/L/E or /L/E you have to repair permissions and rebuild kernel cache after moving the drivers to any of those locations.

 

Repair permission and rebuild cache

sudo chmod -Rf 755 /L*/E*
sudo chown -Rf 0:0 /L*/E*
sudo chmod -Rf 755 /S*/L*/E*
sudo chown -Rf 0:0 /S*/L*/E*
sudo touch -f /L*/E*
sudo touch -f /S*/L*/E*
sudo kextcache -Boot -U /

Now for bluetooth, what combo card (WiFi+BT) are you using?
