Battery Notifier 4.2.1 for Mac
Mac UtilitiesBattery Notifier is a small utility that keeps an eye on your MacBook battery so you do not have to. macOS only warns you at fixed levels and says little about battery health over time. This app lets you set your own alert points for low charge and full charge, pick a sound you will actually notice and glance at a simple health view when you want more detail. It sits quietly in the menu bar until it has something worth saying. Updated Aug 17, 2026.
Key Features
