A pop-up is a window that suddenly appears (pops up) when you select an option with a mouse or press a special function key. Usually, the pop-up window contains a menu of commands and stays on the screen only until you select one of the commands. It then disappears. Some of these pop-ups are disruptive advertisements however some are helpful and provide important information. Please follow the instructions below to enable/disable the pop-up blocker in your web browser as needed.

• Click “Safari” in the upper left corner of your screen and select “Preferences...” from the menu.

• A new window will appear near the center of the screen. Click the tab labeled “Security”. To disable or block pop-ups, put a check in the box labeled “Block pop-up windows”. To allow pop-ups, leave it unchecked.
