I bought the brand new Macbook Pro Retina that came with Mavericks. When attaching documents to emails, etc., it is taking my Finder forever to load the contents of the directory I am trying to access. Is anybody else experiencing the slow loading Finder in Mavericks? Any suggestion for a fix?
After upgrading to Mavericks, many users discovered that a few things that are rather annoying with the Finder on Mavericks. The Finder is rather laggy and seems to take high CPU. To fix the Finder slowness and high CPU usage, the one solution which proved workable is to trash the plist file and forcing it to rebuild.
Trashing the com.apple.finder.plist file basically resets Finder to the default settings. When this file is removed, you will need to reconfigure custom Finder preferences if you have made any through Finder > Preferences. This includes things like the default new window, tab preferences, things shown on the desktop, changes to search preferences, sidebar items, file name extensions and so on.
If you're satisfied with the command line, you can use the following command which puts the entire sequence into a single command string:
rm ~/Library/Preferences/com.apple.finder.plist&&killall Finder
Both the above commands will help you trash the plist file, decrease CPU usage and speed up your Finder. Compared with the picture below with that in the beginning of this article, you can find that the CPU usage has decreased dramatically from 198.7 to 1.2. Quite a huge improvement, right?
Besides Finder slowness, Mavericks upgrade might also cause other problems like Mail crash and Wi-Fi disconnection. In case of such problems, you can check the post 5 Troubleshooting Tips for Mavericks which provides detailed solutions for you.
