detailed MacOSX help

[viaspiaggia]

hi all you osX wizards. hoping you can help.

i have a bunch of machines set up in a studio that were all given very generic names when they were set up, so the main use on ALL of them is "joe." not very descriptive now that we're sharing files and trying to identify user folders. so i want to change the short user name which is what gives the "user" directory its name. the accounts pane does not let you change the short user name - its grayed out.

what's the easiest way to change that short user name? and/or where can i go online besides apple for good osX help?

thanks!!!

TITLE
Mac OS X: How to Change User Short Name

Article ID:

TOPIC


Mac OS X does not allow you to change the name of a Home directory, and thus you cannot change the user's short name. You may use the workaround in this document to get the desired effect.

DISCUSSION

Symptom

In the User's pane of System Preferences, the Short Name field is dimmed. You cannot change it.

You cannot change the name of a user's Home directory, which is the folder with the user's short name in the Users folder.

Products affected

Mac OS X 10.0 and later

Solution

Each user in Mac OS X has a full "Name" and a "Short Name" as defined in the Users pane of System Preferences. The short name is limited to 8 characters, and this is the name used to create a user's Home directory (folder) in the Users folder. The name of a Home directory cannot be changed using the graphical user interface (GUI). Though there are other methods by which an advanced user may change this information, the easier and safer workaround is to create a new user with the desired name, then copy the old user's Home directory contents into that of the new user. Follow these steps:

1. Optional step: As a precaution, you may disable automatic login prior to performing this procedure. In the event that you restart the computer for any reason before completing the procedure, this would prevent complications from having displaced the user selected for automatic login. For Mac OS X 10.1.5 or earlier, automatic login is found in the Login preference pane. For Mac OS X 10.2, it is found in the Accounts preference pane.
2. Enable the root user, then log in as root. For further explanation of this step, see technical document 106290, "Mac OS X: About the root User and How to Enable It".
3. For Mac OS X 10.2 or later: Open the Accounts pane of the System Preferences application.
For Mac OS X 10.1.5 or earlier: Open the Users pane of System Preferences.
4. In the Name list, locate the user with the short name that you want to replace. This will be referred to as the "original user".
5. Note whether or not the original user is identified as Admin, which appears in the Kind column to the right.
6. Click New User.
7. Complete the Name and Short Name fields as desired. Be sure that the Short Name is exactly as you want it to appear.
8. For Mac OS X 10.2: Fill in the New Password and Verify fields.
For Mac OS X 10.1.5. or earlier: Click the password tab, then fill in the Password and Verify fields.
9. If the user you are replacing is an Admin user, then select the checkbox for "Allow user to administer this computer".

Note: This checkbox is dimmed and already selected if there is not another Admin user. Mac OS X requires at least one Admin user.

10. Click Save.
11. Quit System Preferences.
12. Click the Finder icon in the Dock.
13. Choose Computer from the Go menu.
14. Open the Users folder in the Mac OS X disk.
15. Open the folder with the short name of the new user that you just created.
16. Drag the contents of this folder to the Trash.

Warning: Do not empty the Trash yet. In the event that you accidentally move contents of the wrong folder, you may recover them from the Trash after discovering your mistake.

17. Choose New Finder Window from the File menu. Be sure to position the new window so that you can see both Finder windows.
18. In the new window, open the folder of the original user.
19. Drag the contents of the original user's folder into the new user's folder (that you emptied in Step 16).
20. Close one of the Finder windows.
21. Open the Terminal application (located at /Applications/Utilities/).
22. Type: chown -R <new_name> /Users/<new_name>

Important: Replace "<new_name>" with the actual short name of the new user you just created. For example, if the new user had the short name "jacques", you would type:

chown -R jacques /Users/jacques

23. Press Return
24. Quit Terminal.
25. Choose Log Out from the Apple menu.
26. Log in as the new user. You should be able to access all of your original files on the desktop and in the folders of the Home directory.

Important: If you do not have access to your original items, log out and log back in as root, then repeat Step 22. Also, be sure that you did not place the wrong files in the Trash in Step 16.

27. Choose Home from the Go menu.
28. Open the Library folder, then the Keychains folder inside it.
29. Select the keychain, which should still have the short name of the original user.
30. Choose Show Info from the File menu.
31. In the Info window that appears, choose Name & Extension from the pop-up menu.
32. Change the name to match the new user's short name.
33. Close the Info window.
34. Open the Keychain Access application, located in the Utilities folder.
35. From the Edit menu, choose "<new_name> Settings". For the user Jacques, this would appear as: jacques Settings
36. Click Change Passphrase.
37. Enter the desired password, then click OK. You may use the same password again or set it to match the login password of the new user.
Note: This step prevents you from discovering later that the keychain had retained an older password.
38. Quit Keychain Access.
39. Disable the root user, as explained in Section III of technical document 106290, "Mac OS X: About the root User and How to Enable It".

Notes

1. If everything is working correctly, you do not need to log back in as root to empty the Trash. The folders you put there occupy a negligible amount of disk space.

2. Depending on what software you have installed, you may wish to rename other files and folders that may have been created under the original user short name to match the new user short name.

3. Once you are certain that everything is working properly, you may want to delete the Home directory (folder) of the original user, which should be empty. For instructions on how to do this, see technical document 106256, "Mac OS X: Deleting a Former User's Home Directory (Folder)".
