Changing the "Use Mac OS 9 Preferences" setting in Mac OS X 10.3

The Classic preferences option "Use Mac OS 9 preferences from your home" is dimmed (or grayed out) when Classic is running. You won't be able to change the setting until you stop Classic.
To change this setting, log in with an administrator account. If you don't have an administrator account, or if your account is managed and you do not have access to change Classic preferences, a person with an administrator account will need to assist you.

After logging in with an administrator account, follow these steps:

  1. From the Apple menu, choose System Preferences.
  2. From the View menu, choose Classic.
  3. Click Start/Stop.


  4. Click Stop.
  5. Click Advanced.
  6. Modify the "Use Mac OS 9 preferences" option as desired.
  7. Click Start/Stop.
  8. Click Start.
