Change any options.
For most settings, you can click 
for more information about the options.
If a red badge is shown on the System Settings icon in the Dock, you need to take one or more actions. For example, if you didn’t fully set up iCloud features, the badge appears on the icon in the Dock; when you click the icon, the settings are displayed so you can complete setup.
To change options for an app, such as Mail or Safari, open the app, click the app’s name in the menu bar, then choose Settings. Some apps don’t offer settings.
