OS X MavericksApp Nap in OS X Yosemite or Mavericks may be slowing you down. Do you want to get the best performance from applications like Lightroom and Photoshop? Turn off App Nap for Photoshop and Lightroom to keep them running smoothly.  I’ll show you how to turn off App Nap on Adobe Photoshop and Lightroom.  The same steps can be applied to almost any application on the Mac.

What is App Nap?

App Nap is a feature in Apple OS X Yosemite and Mavericks operating system designed to help save power.  It works by pausing inactive applications or applications that may be running a job in the background and you aren’t currently using.  This is designed to conserve power, especially when using a battery.  Personally, I think this feature should be turned off if the OS detects the system is a desktop.

 

Adobe recommends that you turn off App Nap.  Diglloyd over at MacPerformanceGuide is reporting that turning off App Nap for applications  such as Photoshop and Lightroom can help these apps.  He has run some performance tests and discovered that App Nap is slowing things down.  App Nap is especially important to turn off for applications that have batch jobs or operations that run in the background, like rendering in Adobe Premiere Pro.  

I’ve turned off App Nap for  both Photoshop CC and Lightroom 5.  Both of these applications are memory and processor intensive; I’ll take the loss of power saving if it gets me any little improvement.

1.  In the Finder, open the Application folder

2. Find the application you want to turn off App Nap for.  In this case, Adobe Photoshop
