my desktop folders won't open anymore when i double click them
iMac (21.5-inch, Late 2013), OS X Mavericks (10.9.5)
Start up in Safe Mode and see if the problem still occurs:
Mac OS X: How to troubleshoot a software issue - Apple Support
Restart holding the "shift" key.
(Expect it to take longer to start this way because it runs a directory check first. Also give it a little time after start because it runs some maintenance routines in the beginning.)
Might be a corrupt .plist.
Do a backup, preferably 2 backups on 2 separate drives.
Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J. When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder. Select Library. Then go to Preferences/com.apple.finder.plist and com.apple.desktop.plist. Move the .plists to your desktop.
Re-launch Finder by restarting the computer and test. If it works okay, delete the plists from the desktop.
If the same, return the .plists to where you got it from, overwriting the newer one.
Thanks to leonie for some information contained in this.
