I'm getting a lot of stalling and high CPU usage when I open folders in Finder for the first time after the 10.9.3 update. Opening that folder again works fine, but expanding a folder of 20-30 files or folders stalls the CPU on these processes for 30 seconds:


I've tried relaunching Finder but the issue still occurs.

  • can you provide Console report at the time stamp

  • @Buscar웃 looking at it now, it seems the console isn't logging anything during these moments. I suspect this might in fact be caused by CleanMyMac 2 clearing local file caches in each directory something, but you'd think spotlight would resolve those. May 19, 2014 at 0:33
  • The same issue here. Did a full recovery using Diskutil (which found quite some issues), but still happening.

  • @SteveS there's an accepted answer on this question -- did you try what it suggests?

This is what fixed the problem for me:

  • Rebuild the Quicklook cache (in Terminal: qlmanage -r && qlmanage -r cache)
  • Rebuild Spotlight index (sudo mdutil -E /)

I'm not exactly sure which one of those two really caused the problem. You can try them separately.
It takes a while to rebuild both the cache/index, but afterwards Finder worked as expected.

    Thanks for those. They executed fine but I still got the issue. May 28, 2014 at 7:21
  • Sorry, false alarm my spotlight is building slowly :) May 28, 2014 at 7:22

    Neither rebuilding the Quicklook cache nor rebuilding the Spotlight index solved the problem for me - folders still take a long time to open, and coreservicesd and com.apple.IconServicesAgent still take up all the CPU.

  • @AlfEaton I had to wait for a few hours. After a few minutes the spotlight progress showed. Jun 6, 2014 at 0:56
