App Nap is a feature introduced in OS X 10.9 Mavericks and has helped to boost battery life for portable Macs as well as reduce power consumption for the non-portable variety. While the feature is pretty great, sometimes App Nap can mess with your apps and put them to sleep when you don’t want them to be. If you need to turn off App Nap, it can be done on a per-app basis by viewing app information, but that’s not a good holistic approach if you’re trying to get if off for good.
With a little work, you can shut down App Nap across the board and make your apps behave more like they did in OS X 10.8 and below. Interested? Here’s how to turn off App Nap for all applications in OS X.

Disabling App Nap for a single app is pretty easy and straightforward, but to do it across the board, you need to use Terminal to get the job done.
Open up Terminal (Applications > Utilities > Terminal) and copy/paste the following command, hitting Return when you’re done.
Once the command runs, you can quit Terminal and relaunch each app you have open, including any running in the OS X Toolbar.
Unlike when you turn off App Nap in the info window, there’s no proof that the process was done correctly that’s easily visible. If the command ran successfully in Terminal it will definitely disable App Nap across the board, but if you want to check it for yourself, open up Activity Monitor (Applications > Utilities > ActivityMonitor) and click on the Energy tab.
As you can see, every app says No to App Nap. This means it’s shut off completely.
Enable App Nap
