OS X replaces the Mac’s control panels with a System Preferences application. By and large, the settings you can customize here are familiar, with a new Aqua look. Unfortunately, there’s no way to get to most of the individual preference-setting panes without first opening the System Preferences application. You can’t drag individual preference icons to the Dock for easy access. And the one-click convenience of OS 9’s control strip — for adjusting your Mac’s volume level, for example — is gone.
