I am doing a rendering that takes 8 hours or so. If I use safari or any other app the rendering loses priority and starts to get superslow.

You can also press Command + I to present the Get Info window, once an application is selected. You will notice there is an option for Prevent App Nap. How to Disable App Nap Completely in Mac OS X May 13, 2014 - 8 Comments App Nap is an energy feature introduced to the Mac in OS X Mavericks that causes inactive applications to go into a paused state, helping to reduce power usage.
In OS X Mavericks, Apple introduced App Nap technology that assists with reducing energy usage by up to 23%. This is a fantastic addition for anyone using a MacBook Air, or MacBook Pro.
In order for apps to go into nap mode, their open windows must be hidden from view and non-active. For instance, if iTunes is in the background playing music, the app will not become in-active. If you stop playing the music, Mavericks will automatically make iTunes nap to conserve power.
For a multitude of reasons, this may not appeal to you. For example, if you use automatic downloads in iTunes then the nap mode will likely impact on your user experience as automatic downloads will not commence until the app is used again.
For the most part, app napping will occur without you knowing about it. If it does cause problems, or should you want to ensure that apps in the background remain running, then select a Mac app from the Applications folder and proceed to File > Get info. You can also press Command + I to present the Get Info window, once an application is selected.
You will notice there is an option for Prevent App Nap. By default this option is deselected. Simply click the selection box, as shown above, to ensure that this app does not go into nap mode.
Please note, there is no way to activate, or deactivate, multiple applications at a time. Therefore, you will need to undertake this process for each individual app. Also, you may find some third party applications don’t support app napping and therefore this option will not be available in those circumstances.

In OS X Mavericks, Apple introduced a new feature called App Nap. This 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 like DVTools don’t complete their tasks in a reasonable amount of time, or better still crash. then it could be due to resources for those apps being cut when they are backgrounded or left unattended. Following this guide will show you how to disable App Nap when theses issues arise.
f you’re noticing that only one application is having difficulties with App Nap, then you can easily disable it by locating the application in question and pressing Command + I (or choose “Get Info” from the contextual menu). In the Get Info window, check the option to “Prevent App Nap” and you’re done. App Nap will no longer affect DV Tool. (Not all applications offer this option, but DV Tools does.)
f issues still persist with your applications and App Nap, or you don’t worry about system resources being utilized resulting in battery life issues (such as on a desktop Mac), then you may want to disable App Nap system wide on your Mac.
To disable App Nap on your Mac completely, simply open the Terminal application (located in /Applications/Utilities) and type in the following command followed by the enter key:
defaults write NSGlobalDomain NSAppSleepDisabled -bool YES
To completely disable this feature, you will need to log out of your account, then restart your Mac. Thanks to Erwin VK3ERW for his kind assistance with this problem , that was giving me grief for a short time over Christmas With a 16Gb iMac had me stumped but gave the Mac hell and DVAP kept crashing After APP NAP was shut down, DV Tools never hiccups and stays on for WEEKS. Job Done Thanks Erwin Peter VK3TQ
