Q: can not open finder - help

Hi sjwood, start up in Safe Mode and see if the problem still occurs?

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.)

If it works as expected in Safe Mode, then it may be just Finder prefs:

In your regular admin user from your Finder "Go" menu hold the option key and choose Library. Then go to ~/Library/Preferences and trash these files:

com.apple.finder.plist

com.apple.sidebarlists.plist

Then, restart, or log out and in again.

(You will have to reset some finder prefs the way you like them.)

You're welcome. Glad it is sorted.
