These items add features or functionality to your computer's system software. To use them with the Mac OS, copy the Extension, Control Panel, or Apple Menu Items (Desk Accessory) to your System Folder and reboot (restart).
CONTROL PANELS ( CDEVS ) can be accessed by using the
  Apple Menu and selecting the CONTROL PANELS folder. This will bring up a list of your currently installed Control Panels. Locate the Control Panel you copied to your System Folder and double-click it.
EXTENSIONS work a bit differently. When you restart your Mac, they stay resident in memory to perform a certain function. To obtain instructions on a particular Extension please read through any document file included.
Note: If you have moved an Extension and it is not loading when you restart your Mac, verify that it is selected, using the Extension Manger Control Panel.
APPLE MENU ITEMS are accessed by pulling down the Apple Menu and selecting it. System 6 users will have to use Font/DA Mover to add the DA to their System file.
