A possible fix for high Finder CPU usage
Authored by: FareThoughts on Jan 17, '09 12:21:56AM

I'm running 10.5.6, and I've had a problem where my Finder eats up the CPU and the fans nearly send my laptop into orbit. Deleting these three files (although it might have just been one of them) and restarting has so far fixed this problem.

Now, my Finder uses about 0.3 percent CPU, and the fans are low. All of my temps are dropping — and so is my blood pressure.

Hint or not, it was a solution for me, and that's all I care about.

Thank you so much.

Also, as a side note, this got rid of some menu icons that were stuck and couldn't be removed by any method. It did not remove any of the ones I actually wanted.

A possible fix for high Finder CPU usage
Authored by: zman60 on Jul 02, '09 04:16:16AM

I have 10.5.5 and I also found high CPU usage from finder. This same fix, 'shotgun' approach did the trick. Prior to doing this, I saw the processes which were causeing the problem but I could not figure out why those processes were a problem. This thread shows a number of potential culprits and I suspect one or more of them can be the root cause. In my case, the preferences being rebuilt worked. I had tried to repair the hard drive, used Onyx, and a number of other things.

I agree with another contributor that Apple should spend a little effort and improve the finder. It is crazy to read these threads that go back for years.

A possible fix for high Finder CPU usage - beware of GIFs
Authored by: KalleK on Sep 13, '09 01:42:07AM

I also agree with zMan60. Let's see if Snowleopard is going to change anything.

I had the same problem for two days - Finder CPU usage at 95-106%. Reading this thread then inspired me to delete a GIF animation from the late 1990's (2 megs, downloaded two days ago to be used in a lecture) from the desktop. Deleting it did the trick.

(MacBook C2D 2G, 10.5.8)

A possible fix for high Finder CPU usage

I'm running Snow Leopard (10.6.1) and just had this problem. Deleting Library/Preferences/com.apple.finder.plist
and then logging out and back in fixed it.

For how long...? Who knows.

Thanks to OP for suggesting this. Wish Apple would take a look at this problem!

Not sure if you noticed how old the original hint is. Amazing how long these problems stick around. On the other hand, I wouldn't be so quick to assume the Finder is stuck when it's using alot of the CPU. It's doing a lot more now than it did in 2004.

Try giving it a chance to complete before trying to kill it or logging out. And remember that the percentages are a sum of all cores.
