Hi guys, In the past couple of weeks, Finder on my MacBook has been ridiculously laggy in doing just about anything. For instance, if I try to rename a file, I can usually count on having to wait anywhere from 3 to 10 seconds for the new name to appear on the Desktop. The same thing often occurs when moving files. Finder also constantly beachballs for ~5 seconds, which extends to things like save dialogs in other applications -- if I open up a Save as... dialog, the app usually hangs for awhile waiting for Finder to figure itself out. During these periods of lag, the computer is otherwise 100% responsive -- I can use other apps, I can open other apps via LaunchBar or the Dock (as long as I don't try to use Finder, which is busy beachballing), and my CPU usage sits at around 90% idle. No problems at all except for Finder constantly beachballing and lagging. Performing disk tasks like moving and renaming files via Terminal complete instantaneously, so it doesn't look to be a problem with my disk. When I started writing this post, Finder was "Preparing to move" one file, and only just now finished. So obviously this is abnormal. I don't recall exactly when these problems started, but it's possible it was around the time I upgraded from Leopard to Snow Leopard. I imagine that reinstalling Snow Leopard would fix these problems, but I'd rather not resort to that. I've got another computer running the same software as far as I can tell that doesn't exhibit any of these problems. Any ideas for things I could try to resolve this?
