How to activate auto shutdown and warning while on low battery?

[arman379416]

Hi
I have OS X El Capitan on my Haswell Ult and having problem on battery notifications. I want it to warn when it reaches 20% and starts warning on each 5% below 20%. Also how to activate auto shutdown while it reaches at 5% like we set on windows?
Thanks

You are asking for a feature that Apple has not implemented.

Also how to activate auto shutdown while it reaches at 5% like we set on windows?

Macs will automatically enter hibernation (S4 sleep, suspend to disk). But getting hibernation to work can be a challenge, so we generally disable it.

The work around is simple: Turn your laptop off when you're done with it, or plug it into a power supply.

So is there any app which can alert or make to shutdown? If you can suggest me...
Also I found this on an article that we should type this code in terminal
pmset -u haltlevel 10and this will make mac to shutdown when it reaches at 10% so will it do the same?
Thanks

I don't know of one (haven't looked).

Never tested it. You can try.

No. That terminal command is for Uninterruptible Power Supplies attached to desktop systems and does not apply to laptops. Type "man pmset" at the terminal for more info.

Has any progress been made on this front? For example a utility which works in macOS High Sierra?

[EDIT]: testing SmartSleep by jinx.de (Patrick Stein) now. Not sure though if it actually auto-powers down or auto-sleeps at x% battery level.. I'll see

[EDIT2]: syscl's IOPowerManagement is even tailored for hackintoshes: https://github.com/syscl/IOPowerManagement
I'll see if it still works on 10.13.6

Have a look at SleepOnLowBattery (“SOLB”). It's open source, works in current macOS, and you can adapt anything to your liking
