I have a Windows share mounted in OSX 10.9 Finder (through +K) that acts bizarre every so often (can't log in sometimes, randomly disconnects from the GUI claiming it can't access the mounted volume).

Usually I have to reboot to force-disconnect this mounted SMB drive; is there a way to do it through terminal? (Like say, using mount?)

Try using umount:

umount -f /your/mountpoint

(-f forcibly removes the mount point)

Yep! That's it-- thanks! –  remus Dec 25 '13 at 5:54


  1. diskutil unmountDisk force /Volumes/DISK_NAME

  2. diskutil unmount /dev/disk0

To get the disk0, which is the Identifier, you can run diskutil list in terminal to see which one it is. See http://osxdaily.com/2013/05/13/mount-unmount-drives-from-the-command-line-in-mac-os-x/

Don't see why this needs to get downvoted, as it is a viable solution. –  Aaron Dec 25 '13 at 5:55
