The only real issue I have with watching movies on my MacBook is forgetting to turn off the screensaver so the screen doesn’t go blank in the middle of a movie. Mac users can choose from a few inexpensive ways to avoid that problem including the free Caffeine app. Here’s another one.
The idea behind Amphetamine is obvious. It keeps your Mac’s screen awake when you want. Unlike Caffeine, Amphetamine comes with a few useful features for the same price.
For example, not only does Amphetamine keep the Mac screen awake, it also lets you choose from a number of useful presets (or create your own).
That means you can schedule activation and deactivation to run or stop automatically at specific time periods throughout the day.
Activation and deactivation is also just a click away with click to the Menubar icon, or use the global keyboard shortcuts.
Amphetamine can be set to open automatically when you start up your Mac and even alert you that it’s running (so the screen doesn’t stay on while you try to fall asleep). Controls are simple to setup, too.
Amphetamine can be set to deactivate when your Mac’s battery power reaches a certain threshold, but if it’s not running then your Mac behaves normally and according to the settings in System Preferences > Energy Saver.
Not bad for free, huh?
