Mac Os X Caffeine App

Dec 19, 2017  Caffeine for Mac OS does not affect the standard parameters of the system, and You can toggle the app on or off whenever you want. The Caffeine lets your computer to stay awake while you need it. The application is useful whenever you want to do some presentations on the computer. It could be a helpful tool for any Mac user who does things that need a temporarily insomniac computer. Caffeine is a tiny program that puts an icon in the right side of your menu bar. Click it to prevent your Mac from automatically going to sleep, dimming the screen or starting screen savers.

Apple does mention about the effectiveness of App Nap in their official website:

“… OS X can tell when an app is completely hidden behind other windows. And if that app isn’t currently doing something for you — playing music, downloading a file or checking email, for example — App Nap conserves valuable battery life by slowing the app down.”

The screen of your Mac automatically turns off after a certain duration of inactivity. Eventually, the entire Mac goes into sleep mode depending on your configured power settings. If you have a background app running with the App Nap feature enabled, it won’t be able to prevent your Mac from going into sleep mode. And once sleep mode is activated, all your active apps will stop working.

When you resume work on your Mac, you might notice that background activity (for example, downloading files via μTorrent or other download managers) have been paused or that the internet had been disconnected while in sleep mode. Of course, OS X did this to save power, but the feature is not really helpful in this case.

If App Nap is disabled for a particular app, it won’t allow your Mac to go into sleep mode while it’s active, even in background. You can see this in action when you’re playing music in iTunes and the display turns off. In this case, iTunes keeps playing music in the background. This is because App Nap is disabled by default for iTunes.

Caffeine is a useful app that sits on the Mac OS X menu bar and prevents your Mac from automatically going to sleep. Thus, it helps applications to keep running over long duration of inactivity. Depending on your requirement, you can activate Caffeine from a few minutes to a few hours or even indefinitely, when you need background tasks to be performed without any interruption. You can even turn off the display by using the Ctrl+Shift+Eject or Ctrl+Shift+Power shortcut to save power.

NoSleep is similar to Caffeine in the way that it allows applications to keep running over long periods of inactivity. But unlike Caffeine, which only prevents your Mac from automatically going to sleep, NoSleep disables the sleep feature completely as long as it is enabled. This means your Macbook won’t go into sleep mode even if the lid is closed and background apps will keep running without any interruption. But it also means that your Mac might probably consume a lot more power when NoSleep is enabled.

To save some power when NoSleep is active, you might want to lock your Mac’s screen with the Lock Screen option from the NoSleep menu. Alternatively, you may just turn off the display by using the (Ctrl+Shift+Eject) / (Ctrl+Shift+Power) keyboard shortcut.
