This MBA is experiencing several SMC related issues including;

* Macbook will not go to sleep
* Magsafe charger will not light up
* Fan goes full force the second I turn on the computer
* Keyboard backlight will not turn on
* MacBook not recognizing the battery
* Wont connect to Wi-Fi

Because it failed while updating to MacOS 10.14 Mojave, and is only having these issues afterwards, I am convinced an SMC update failed.

I am trying to manually reinstall SMC firmware using the following forum https://discussions.apple.com/thread/4855319?answerId=22024754022#22024754022

However I am getting this error while running the command “SmcFlasher.efi -reset 1”;

“Warning (at least one SMC ) is not in the expected AppCode mode, but in ‘U’ mode

.

To enter AppCode mode run SmcUtil with the ‘reset 1’ option.”

———————————————————————————————————————————————

How can I run “SmcFlasher.efi -reset 1” without getting the error?

Is there another way to manually flash SMC?

Thanks in advance!
