- Click the checkbox to select the items you want to install, then click Install. Type an administrator name and password (the name and password you used when you first set up your computer).
When the updates complete, Software Update checks for updates again. It does this because some updates require that you have installed previous updates. For more information, search for Software Update in Mac OS Help.
