Hey I came here looking for help and found none..But I didn't give up hope just looked else were...My problem was I could not mount dmg's, cds, zip disks, ect .Any way the solution i found was this. (5). After doing some more research on this problem, I came across this post on another forum which indicated this may be a problem with the unknown user on your OS X system. The unknown user is one of those hidden Ids, like root, that has special UNIX functions. Eric Wing (another Helper) and I developed the following procedure for checking and recreating the unknown user if yours is missing. Verify the existence of the unknown user: There are two ways to check your system to determine if the unknown user is missing: A. With NetInfo Manager 1. Open NetInfo Manager (in the Computer > Mac OS X > Applications > Utilities folder) 2. In the middle column of the resulting window, select (click once) on users. 3. The column just to the right should fill with the list of users. See if unknown appears in the list. B. 'Get Info' method 1. Select any file, preferably one you own (otherwise you'll need to authenticate first). 2. Perform a Get Info (Command+I or Apple+I) key combination on the file. 3. Select the disclosure triangle for Ownership and Permissions panel. 4. Click the Lock icon. 5. Click the double arrowhead next to the 'Owner: owner_name' field. 6. In the resulting list, unknown should appear in the list of potential owners. To recreate the unknown user: 1. Open NetInfo Manager. 2. Click the Lock icon in the bottom left hand corner of the window to authenticate, and authenticate. 3. In the middle column, select users. The column just to the right should fill with the list of users. 4. Highlight/select nobody 5. Under the Edit menu, select Duplicate; or press the key combination Command+D (Apple+D). This will create a new user, nobody copy. 6. Select the newly created user, nobody copy. 7. In the bottom half of the split screen, you'll see Properties and Values for nobody copy. You'll need to edit some of the Values for nobody copy to make them what they should be for unknown -- this will 'convert' nobody copy into unknown. The following are the default values for unknown: Property Values expire 0 realname Unknown User name unknown passwd * uid 99 _writers_passwd unknown change 0 shell /dev/null home /dev/null gid 99 8. Change the following Property values to the values shown in the table in step 7: realname, name, uid, _writers_passwd, gid. Do so by double-clicking on the Values for those propteries and edit the contents with the values for unknown in step 7. 9. In the menu bar, select Domain > Save Changes. 10. Agree to Update the copy of the database if you're sure of your editing. 11. You should now see that nobody copy is now unknown 12. Quit NetInfoManager. You should probably Restart at this point. |
