As an example, my Finder is in no state to be normally removing files. Just trying to open/relaunch it cases it to never appear and show the spinning color wheel.
As a common search result in Google, there is point in replying to this post 🙂
I may try the Terminal method to see if removing the plist file helps, only after making a backup of course, and if not, reboot, and that will likely help. I think my problem is that I was mounting a remote share that never succeeded, or did, and Finder is just having trouble trying to communicate with it.
Here is some Terminal output:
> mount
/dev/disk1 on / (hfs, local, journaled)
devfs on /dev (devfs, local, nobrowse)
map -hosts on /net (autofs, nosuid, automounted, nobrowse)
map auto_home on /home (autofs, automounted, nobrowse)
map -fstab on /Network/Servers (autofs, automounted, nobrowse)
//user@remote/share on /Volumes/share (smbfs, nodev, nosuid, mounted by user)
> umount /Volumes/share
umount(/Volumes/share): Resource busy -- try 'diskutil unmount'
> sudo diskutil unmount /Volumes/share
Password:
Unmount failed for /Volumes/share
The Disk Utility GUI does not show this mounted remote share, and I'm not sure that it would anyway, but just checked.
I have tried the Command+Option+Esc method, just as I have been Right-Clicking the dock icon, waiting for a small delay, holding Option, and selecting Relaunch from either place, in the dialog or pop-up context menu.
One note that is interesting and consistent with my (un)mount issues is that after a relaunch, Finder will respond to a right-click more immediately, but if I try to open the program again, the hanging occurs.
