Mac OS X Mavericks: Finder Slow or Unresponsive? Blame App Nap.
February 17, 2014 Leave a comment
I’m partial when it comes to acknowledging Mac OS X’s quirks (having used Windows for a very long time), but there are things and there are…things.
After OS X Mavericks upgrade, I had two big qualms with Finder:
- It would go unresponsive for about 10-15 seconds after a wake from suspend. Consistently. Every-single-time.
- It would blink for about 4-5 seconds before loading any directory. Throughout.
This Apple support thread has a post from rubyreddevon that indicated that AppNap might be the culprit.
Issuing this:
sudo defaults write com.apple.Finder NSAppSleepDisabled -bool YES
The AppNap integration was disabled, and presto, Finder shines and is zippy again.
Update: This way or the Menu way: Two ways to AppNap integration management for Mac Apps.
