Hi,

Question: Did you select 'Reset NVRam' each time you made the changes

Sorry:  I didn't   

 

Now I copied  3400_12C_5  Reset nvram and reboot     but still no trackpad :-(

Should I retry your other options as well?  ( I'll do it anyway.... )

 

My  Dell 3400 has one other problem:   after a reboot or cold start the HDMI-port only works after taking it out and back into the Laptop,  and the HDMI-port doesn't survive a sleep-session.

@Jorge1964, I have upgraded to OpenCore 0.64 but still no Trackpad. :-( I shall take a look at the EFI from davidfrei7as, hope that will solve it.... If I get it to work, I 'll post a EFI here. 

 

Edit:

@Jorge1964, Thanks for pointing my to davidfrei7as: his EFI is pure gold.

Guys, please keep this thread on-topic and open separate ones for unrelated matters. Thank you. Your discussion about wireless and iMessages was moved to its own thread.
