‘How can I keep my Mac from falling asleep?‘ In the age of Netflix, streaming music and videos, that’s a valid question. Here’s an answer and a free Mac app that’s the best solution I’ve run into.
The Benefits Of Sleep
A Mac that falls asleep isn’t a bad thing unless it falls asleep when you don’t want it to, which is usually when you least expect it to.
Why does the Mac sleep? Apple hides the sleep function settings in the Energy Saver preferences in the System Preferences app.
The two slider bars control when the Mac sleeps (how many minutes), and when the display sleeps (how many minutes) with an option to put the Mac’s hard disk drive to sleep).
The advantages to having the Mac sleep or the display sleep after so many minutes of non-use are obvious. Battery life. Screen life. Mac life.
There are times when the Mac falls asleep when you don’t want it to. Netflix comes to mind. Hulu. Or, watching most any movie or listing to streaming music while doing something non-Mac like.
Enter Caffeine, the free Mac app that keeps your Mac awake when you want it to be awake so you can watch or view whatever you want without having to wiggle the mouse or touch the trackpad to keep it awake.
Caffeine resides in the Mac’s Menubar so it’s easy to turn on and turn off. It can startup automatically when your Mac starts up (with a setting to activate upon startup– or not).
You can set the duration default but that’s about it. It just works. All Caffeine does is keep the Mac awake while you watch something on the Mac’s screen. For me and for most of the students and teachers in our school, Netflix is the main culprit.
Caffeine doesn’t do much but what it does is often needed so the price tag is just right.
