Hi Jake,

 

Very busy this week. I m quite sure keyboard is PS2 so all buttons are on a the same board as touchpad. 

Do you think I must try to re install High Sierra ?

 

PS: Just tried, I had already installed high Sierra on an external same result, no buttons .. ?

My laptop is 90 % finished so I can now wait for a final solution.

Your help greatly permitted to me to go forward

Working on getting High Sierra installed on a 5590, but running into several issues. Tried the configs posted in this thread, but no luck:

  • Not working as of now:
    • touchpad
    • touchpad buttons
    • trackpad (not important)
    • USB mouse/keyboard (the mouse is receiving power, as the red LED is on, but no input is being passed through)

Not having a mouse is preventing me from getting past the install, as I can't select the HDD to install by using the tab key.
