Update: MacBook Air SMC issues after software update
Links to previous questions; MacBook Air SMC issues after software update
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/485...
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!
