If you need to activate it for longer, a right click on the icon will allow you to choose how long you want to activate Caffeine for. If you left click the Coffee cup icon you’ll activate Caffeine for the default time, which can be set from indefinitely to 5 hours. When you need to keep your MacBook’s display awake, just click the coffee cup and your display will stay awake. The app can be configured to run at startup and resides in your system bar. Rather than moving the mouse every so often, you can download a small app called Caffeine which will keep your display “awake” while you read or work.Ĭaffeine is a free app, available in the Mac App Store, which can be configured to keep your MacBook display from dimming while you work.
This automatic dimming is great for battery life, but can be a pain when you want to read a long webpage or PDF. MacBooks will automatically dim the display after a short period of inactivity.
