Well, here’s something for our Mac OS X users! Yes, due to some security reasons, it’s always a good idea to locak your Mac screen when you step away from the keyboard. On the other times, there are times where you’ll be away from your Mac, but you don’t want to have to re-enter your password to login, or you just don’t want your screensaver activating or your Mac sleeping. Let’s have more information on this from below.

How to temporarily prevent a Mac from sleeping

Well, there are three ways to temporarily prevent Mac OS X from sleeping or activating the screen saver,

1. Caffeine

Caffeine is a free menu bar utility that is available through the Mac App Store, and it sits in your menu bar. Well, when you click on the cup of coffee, it prevents your Mac from going to sleep for a present amount of time : from indefinitely to 5 minutes. Hence, if you are interested in Caffeine app, then you can grab it from here. [Mac App Store link]

2. pmset

Well, if you don’t want to install another app, you can mimic the effects of Caffeine by using a command line utility called pmset. Simply, launch the “Terminal” and type;

pmset noidle

Actually, this will prevent your Mac from sleeping indefinitely until pmset is no longer running. Also, you can stop pmset from running by hitting “Control+C” in the same Terminal window. Actually, pmset is a power management utility that you can use to set sleep and wake times, but the noidle flag simply provides a single use sleep prevention method.

3. Screen Saver Hot Corners

Also, there is another option to set a screen saver Hot Corner from System Preferences -> Screen Saversn -> Hot Corners. Simply specify a corner and set it to “Disable Screen Saver” and and anytime you slide the mouse into that corner, the screen saver won’t activate, which doesn’t prevent the system from sleeping though.
