How to Disable App Nap Per-App in OS X Yosemite

Jan 18, 2015 by iHash 3 Comments

App Nap feature was designed to cut CPU and other computer resources to power-hungry applications when those applications are not currently in use.

It’s one of several OS X features that has helped increase the battery life on Mac portables, but unfortunately, this feature isn’t without downsides. If you’re noticing that applications don’t complete their tasks in a reasonable amount of time, then it could be due to resources for those apps being cut when they are backgrounded or left unattended.

To disable App Nap for certain app follow these steps:

Step 1. Go to Applications folder

app nap disable on app 1

Step 2. Locate application and press Command + I or right click on application and chose Get Info from the contextual menu

app nap disable on app 2

Step 3. In the Get Info window, check the option to Prevent App Nap

App Nap will no longer affect this application but not all applications offer this option.

 

To disable App Nap system-wide in OS X Yosemite check this tutorial.

      You are kinda right. This function must be supported by the app and not OS X. There are just a few apps which supports app nap prevention.

      Yes it is but not for all apps. If app doesn’t support app nap prevention then option is not visible in app info. But there is option to disable app nap globally https://www.ihash.eu/2014/12/disable-app-nap-system-wide-os-x-yosemite/
