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 .. ?

You will have to get help from the developer of VoodooI2C then. Might be a known issue, I haven't been following the development.

NM, I see you've already posted there.

Thank you for answer, I have seen a post on  another forum talking aboute I2C I will try too post on it.

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

Your help greatly permitted to me to go forward

 

Thanks Jake

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.
