ℹ It's absolutely worth a try. Here's why:
1) We know AppNap is a new feature that puts the finder to sleep when not in use
2) So logically we can infer that disabling AppNap will solve the 'AppNap' lag
3) We can fix it by going to Applications/Utilities/Terminal to issue a very basic command
➕ The command is:
sudo defaults write com.apple.Finder NSAppSleepDisabled -bool YES
ℹ Translated into English, it reads:
sudo = I am a user who has administrative rights on this operating system
defaults = My request concerns a default setting of this operating system
write = I am going to 'write' a change to that default setting
com.apple.finder = The default setting is in the Finder, which is an Apple application
NSAppSleepDisabled = The setting is called 'NSAppSleepDisabled' (aka AppNap)
-bool = I am issuing a boolean data command (a 2-setting command i.e. true/false, yes/no)
YES = I am saying 'yes' enable 'NSAppSleepDisabled' (so AppNap won't cause Finder to sleep)
⚠ This will NOT fix all issues related to OS X Mavericks Finder lag.
Why? Another issue is causing your Finder to lag or you issued the command wrong
Then what might the other issue be? A laundry list of possibilitiess...
What other things could I try?
1) Verify disk permissions. Repair permissions. (a quick and easy option)
2) Run a clean install of OS X Mavericks (a more time-consuming difficult option)
How do I do those things? Google it.
I hope this demystifies the "scary" command and/or explains why it might not work for everyone. 😎
Here's some follow-up information regarding my earlier reply to rubyreddevon:
I've tested this command on 3 macs running mavericks and it worked on all of them. However, I must add that:
- Finder lag resolved both with and without issuing "sudo", most likely due to my configuration
- 1 of the macs affected was a brand new, 15" Retina MBP--maxed out hardware yadda, yadda, clean install
- The 2 older macs had disk repair run regularly (2008 mbp 15" & 2012 Macbook Air)
I suggest that the steps be taken in this order:
Uninstall any apps that may complicate things with the finder i.e. TotalFinder, XtraFinder, etc, just to simplify things
Uninstall any unused apps, again, just to simplify things and get unnecessary bloat out of the way. (for this you may like to try the free app called AppCleaner).
Securely empty your trash
Power down, power back up--just to clean out caches, and terminate other background tasks.
Verify disk permissions and repair if necessary
Open up terminal and issue the command (above)
Cross fingers
Thats just my 2 cents. Steps1-5 are just basic troubleshooting steps (+/- the restart). I hope it works for you, if it doesn't there could be other issues at play, which may be mavericks-based and/or system-specific.
