If your company is using a Mac to connect to the Internet using an ordinary telephone line and the computer’s modem, you can prevent it from connecting automatically. Unlike Macs that are always connected to the Internet via cable or DSL, a Mac that uses a dial-up connection provides you the option to disable automatic connection. You can also disable automatic wireless connections to the Internet by disabling AirPort, which is Apple’s name for Wi-Fi connectivity. Keeping your Mac disconnected from the Internet when you do not need access can help protect your computer from intrusive hackers, as well as keep the telephone line available for calls or faxes.
- Click the Apple icon at the top of your Mac’s screen, then click “System Preferences.”
- Click “Network,” then click modem from the “Show” drop-down menu.
- Click the “PPP” tab, then click “PPP Options.”
- Click the check box to de-select the option to “Connect Automatically When Starting TCP/IP Applications.”
- Click “OK,” then click “Save.”
- Click the Apple icon, then click “System Preferences.”
- Click “Network,” then click “Airport.”
- Click “Turn AirPort Off.” Alternately, you can click the triangle-shaped AirPort icon on your Mac’s menu bar, then click “Turn AirPort Off.”

How to Delete YouTube Popups
Video creators on YouTube have the option to add annotations to their videos in the form of pop-up messages. While the pop-ups can add interesting information, they’re very distracting when you’re showing a video. To make sure your audience has its attention on the video and not on the annotations, disable the pop-ups before you start playing the video. You must have a YouTube account to change your settings so that annotations no longer appear on your videos.
- Sign into your YouTube account. If you don’t have one yet, you can sign in with your Google account. The services are connected.
- Click the downward arrow icon, then click “Settings.”
- Choose “Playback,” and then uncheck the box under “Annotations.” Click “Save” to finish.
