Know exactly when to unplug.
Battery Beacon sits in your menu bar and alerts you the moment your Mac hits 95%, 100%, or any charge level you set — so you stop babysitting the charger and stop overcharging.
Menu-bar only · Liquid Glass on macOS 26 · Analytics off by default
Small app. One job. Done well.
Lives in the menu bar
No Dock icon, no clutter. Your battery percentage and a charging bolt sit right next to the clock.
Your thresholds
Configurable alert levels with simple sliders. Defaults to 95% and 100%, or pick any percentage.
Native notifications
A standard macOS notification fires while you are plugged in, right when you hit your level.
Optional alert sound
Turn on a sound if you tend to miss banners, or keep it silent.
Resets on unplug
Thresholds re-arm automatically every time you unplug, so the next charge just works.
Built for macOS
Written in SwiftUI and matches your system theme, including Liquid Glass on macOS 26.
How it works

Set your thresholds
Pick when you want to be notified. Defaults to 95% and 100%, or set any percentage you like.
Get notified, then unplug
A native macOS notification fires while you're plugged in. Unplug, and thresholds reset for next time.
