Yes, find out what is causing the Finder to malfunction. Killing a window only covers the symptoms, but it does not fix the problem.
A first guess is: bad com.apple.finder.plist file in /Home/Library/Preferences/. Delete the file.Mac Pro 2.66 Ghz; MBP Unibody; MBP C2D 2.33 Ghz; 11" MBA, Mac OS X (10.6.4), iMac C2D 17"; MB 2.0 Ghz; iPad 32G; 80GB iPod Video; iPod Touch; iPod Nano 2GB
Brilliant thanks so much. Works fine now even after a restart.
I deleted the file "com.apple.finder.plist"
Goto Terminal and input
(this restarts the finder)
Thats will bring the Finder back to 1%CPU usage !iPhone OS 3.0
I have the same problem. As soon as a finder window is open my cpu usage goes up to 100% - when I close all finder windows - problem gone.
deleting the com.apple.finder.plist file and restarting the finder didn't change anything however...
does anyone have another idea?Macbook 2006, Mac OS X (10.6.6)
I had the same problem this morning. Removing the plist file seems to have done the trick. Thanks.
woondidu - If you have a lot of files, especially jpegs on your desktop, clean your desktop up this has also been known to cause finder to chew up CPU.MB PRO, Mac OS X (10.5.4)
AH this problem showed up again this morning and based on my playing around, I think Finder was choking on my external USB drive. I ran disk repair and there were several errors reported and repaired. Been running nice and quite for several hours now.MB PRO, Mac OS X (10.6)
This did the trick for me just now. Moved the com.apple.finder.plist file to the trash, relaunched the Finder and everything immediately starting winding down.17" MBP 2.33Ghz C2D 3GB, Mac OS X (10.6.6)
Deleting all the screen captures on the desktop worked for me. CPU was about 85% and disk read was about 5MB/sec. Deleting about 30 png files immediately resolved the problem without reboot.Macbook pro late 2009
As of 10.6.6 I have a version of this problem, completely reproducible,
tied to checking the "calculate all sizes" in the "Show View options"
Closing the Finder window thus checked, or unchecking the box restores
the conventional Finder usage (0-0.4%) on an Intel Core i7 2.2 GHz 4-core.
Previously reported around 10.6.2. in Sept. 2009
I have a SSD disk that quickly calculates the sizes, but the Finder remains
at 100% for one processor core, no matter how long the Finder window
so checked (calculate all sizes). The window calculations are clearly done.
In my case removing the preference file (com.apple.finder.plist) had no effect.
It is hard to imagine this bug lingering until 10.6.6, unless the "tickle"
is rather subtle.
Quite reproducible. No time today to progressively delete preference files.MacBook Pro, Mac OS X (10.6.6), 128 GB SSD
Thanks Phil.H. I like having "calculate all sizes" set, especially since my MacBook Pro is using just about all available space. But, unchecking "calculate all sizes" restored typical cpu usage instantly.MacBook Pro, iMac, Mac Mini, Mac OS X (10.6.6)
I solved this issue by setting my finder preferences for "New Finder window show:" to my home folder... My issue was that it was defaulting to "All My Files"--- that caused finder to scan everything, images, thumbnails, etc and get up over 100% of cpu usage.
