I have a Macbook and I just hate it when it crashes because the battery is too low. I'm a snoozer, when I get the Low Battery Warning, I never plug it in right away, I know I should but I don't. Then my computer crashes without a second warning and goes into sleep mode and it kills me. So I wanna know is there an app that can block the use of my computer at lets say 3% (unless its plugged in) so that I dont have a choice but to plug it in. OR A pop up countdown would be even better something like that LOW BATTERY WARNING YOUR COMPUTER WILL GO INTO SLEEP MODE IN APPROXIMATELY 160 SECONDS Wouldn't that be awesome? Long story short I just wanna prevent my computer from crashing because of a low battery its so aggravating.
