Windows File Sharing user checkbox uncheckable I seem to be unable to complete the setup of sharing a folder via SMB.  I have turned on file sharing and have checked 'Share files and folders using SMB' but I cannot choose a user account under the section called Windows File Sharing:


  Sharing files with some Windows computers requires storing the user's
  account password on this computer is a less secure manner.  When you
  enable Windows sharing for a user account, you must enter the password
  of that account.




I can see my computer on the network from another computer but I cannot access the file shares with this mac's username and password.

Any help would be appreciated.  Thanks!
This might help ... basically you need to create a "share-only" user on the Mac.
