Mac OS X 10.2: About Using Mac OS 9 Control Panels in the Classic Environment

Note: The System Preferences application contains any "preference pane" to which the table refers. For the best possible experience, you should use System Preferences in place of certain working Classic control panels. When this is the case, it is stated in the Notes column. The Notes column also describes when a working Classic control panel offers less than its full feature set in the Classic environment.

Mac OS 9 control panels in Classic

Classic Control Panel	Usable?	Notes
Appearance	Yes	Changes that are not apparent in Classic appear when, if ever, you start the computer up from Mac OS 9. The desktop picture set in the Desktop preference pane always appears, whether or not you are in Classic. Sound Track only works in Classic applications. Changes to the System or Views font only affect the Classic environment and Classic applications.
AppleTalk	No	Use the Network preference pane instead. See technical document 107080, "Mac OS X 10.2: How to Make AppleTalk Active or Inactive in the Classic Environment".
Control Strip	No	None
ColorSync	Yes	Changes affect Classic environment applications only.

Extensions Manager	Yes	These settings are also found in the Advanced portion of the Classic preference pane.
