With Amphetamine, you can effortlessly override your energy saving settings and keep your Mac awake. You just have to tap on a single icon on your macOS Menu Ba. Once activated, your system will stop going to sleep. You can also set it up so that Amphetamine only kicks on when it notices that a particular app is running.
With the menu bar app, you receive an alert when your MacBook is plugged in or unplugged, and when your battery percentage reaches a preset level, so you know when to plug in your computer to keep it from dying or to unplug it and save your battery life.
Battery Indicator shows the remaining battery time or percentage right in your menu bar. This is especially useful on macOS Sierra 10.12.2 or later where clicking the battery icon no longer shows the remaining time.
This menu bar app provides information and stats about your MacBook’s battery and records all these data as well as the total battery- and usage time of your notebook.
Caffeine prevents your Mac from automatically going to sleep, dimming the screen or starting screen savers. Click it again to go back.
