I have replaced a faulty logic board in a Macbook Air 6.2 (Mid 2014), after the replacement logic board was installed, the ssd has been erased, a clean version of mavericks was installed from internet recovery and then updated to majave, all without issue.
The problem is the keyboard and trackpad, unfortunately they don't work at all. I have been using a USB keyboard & mouse to get it setup. Strangely though, the keyboard startup key combinations do work, also, the keyboard and trackpad work when it is booted into startup manager (option key on boot). From startup manager, keystrokes can be used to enter the wifi password and the cursor behaves as normal, as soon as you move past startup manager into any of the other modes such as USB OSX boot disk, Internet recovery or the OS then they don't work. It is an freshly erased ssd with a clean install of OSX, I have tried resetting the pram and also resetting smc and I'm now out of ideas. Hopefully someone here will be able to help as I'd really like to get this resolved quickly as it is a priority repair for a client.
