All Macs come with Apple's free Safari web browser already installed, so you can start surfing the Internet. When you visit a website that makes money from advertising, you may see pop-up ads, which can be quite annoying. While you want to read a news story, for example, a small pop-up window will appear, trying to get you buy a product. The advertiser wants to make sure you see the ad, which you will have to do even if only for a second when you click on the pop-up window to close it. Fortunately, you can block distracting pop-ups with Safari.
Step 1
Double-click on the Safari icon in the Applications folder, or double-click on the Safari icon in the dock, located at the bottom of the Mac's screen, to launch the application.
Step 2
Click on "Safari" from the menu.
Step 3
Click on "Safari" from the menu.
Step 4
Click on "Block Pop-Up Windows. You will now see a check mark next to this option, which shows it has been selected. Now when you surf the net, Safari will block pop-ups.
Step 5
Click on "Safari" from the menu and then click "Block Pop-Up Windows" again when you need to stop Safari from blocking pop-ups. The check mark will be removed. Some sites use pop-ups not for advertising, but to provide you with useful information, such as details about a product you are researching, or an explanatory diagram when you click on a page.
