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! – brandonscript 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

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