Beep Alert when Battery is below 10% — MacOS.

My MacBook shut down most of the time because I am working and lazy to put the charger in.

It shows a notification at 10% battery but I usually forget.

How about a irritating Beep sound which start when battery is below 10%

Save the following script somewhere — You can download it from https://raw.githubusercontent.com/nsisodiya/ubuntu-battery-alarm/master/mac/mac-battery-alarm-service.sh too

#!/bin/bash
while true;
do 
    echo ""
    charging_level=$(pmset -g batt | grep -Eo "\d+%" | cut -d% -f1)
    charging_status=$(pmset -g batt | grep charging | cut -f4 -d" " | cut -f1 -d ";")
    echo "Cuttent charing level is $charging_level and Battery is $charging_status"
    if [ "$charging_status" == "discharging" ];then
        if (( charging_level < 10 )); then
            echo "Battery is LOW and Less than 10% & Discharging"
            #amixer set 'Master' 100%
            afplay /System/Library/Sounds/Blow.aiff
        fi
    fi

    if (( charging_level < 5 )); then
        sleep 2;
    else
        sleep 5;
    fi
done

This script basically checks the battery level and plays the beep sound.

and you can use “Automator” in the macOS to run this shell script.
