Hi
I have problem with my Macbook Air.
The internal keyboard and trackpad doesn't work anymore.
Keybord illumination is working fine and the power button also. If I plug in an USB mouse and / or keyboard both work fine.
I changed the cable from top case to logic board - still not working.
With the external keyboard, I did the hardware test - everything ok - and nvram reset - no change.
Some people told me about troubles with Sierra. Since yesterday I have the latest version - but still not working.
Does anybody have another idea to make the MacBook work again?
I need it!
Thanks, Stig

Is there a possibility to identify the problem?
Software? Diagnosis Subsystem?
'''Problem Update:''' After a SMC reset the keyboard and mouse it's working for ~ 1 minute (with interuptions).
Is the problem the USB controller?
Does anybody have any advise?
