enable smc charging not possible.

[thiccasss]

After I disable battery limit it won't charge anymore and smc charging is still disabled. If I write "battery charging on" in terminal, it still won't turn on and charge. Only way is to reset smc by restart the Mac.

how can I turn on smc charging again without restarting the Mac anytime?

I had to uninstall to get charging past 80% going again. When using the CLI to try and turn on charging, I was getting the following output - I suspect the error of interest is Error: SMCWriteKey() = e00002bc:

I'm on a MacBook 13" M1 2020, macOS version 14.5. It broke on macOS version upgrade, but I can't recall which one as I haven't travelled for quite a few months.

I had the same issue. Not sure why, but the enable_charging function disables charging again ¯\_(ツ)_/¯

https://github.com/actuallymentor/battery/blob/481610ac05a6fedefb36d43032705cd9136f4691/battery.sh#L185

function enable_charging() {
    log "🔌🔋 Enabling battery charging"
    sudo smc -k CH0B -w 00
    sudo smc -k CH0C -w 00
    disable_discharging
}

To re-enable normal charging behaviour, try

battery maintain stop
sudo smc -k CH0B -w 00
sudo smc -k CH0C -w 00
