Applications

You can use the Applications pane to execute applications present by default in OS X but not easily accessible to you.

Screen Sharing:

With OS X, you can connect to another computer on your network and display that computer’s screen on your computer. While you share the computer’s screen, you can control what happens on that computer, such as opening documents or applications; opening, moving, or closing windows; and even shutting down the computer.

You can also share your computer’s screen with another computer on your network.

Network Diagnostics:

You can use Network Diagnostics to help solve Internet connection problems. If you can’t connect to the Internet, Network Diagnostics opens and walks you through solving the problem.

You can use Network Diagnostics to diagnose problems related to your Ethernet, AirPort, or internal or external modem connections. If you are trying to connect to the Internet using another method, see the documentation that came with your Internet account.

Wi-Fi Diagnostics:

Use Wi-Fi Diagnostics to diagnose your wireless network, record network events, capture network traffic, and turn on debug logs.

Wi-Fi Diagnostics produces a report that can be sent to Apple for analysis.

Character Palette:

Use Character Viewer to enter special characters and symbols, such as mathematical symbols, letters with accent marks, or arrows and other “dingbats,” into your documents.

You can also use the Character Viewer to enter Japanese, Traditional Chinese, Simplified Chinese, and Korean characters, as well as characters from other languages.

The Character palette is available in most applications from the Special Characters command in the Edit menu.

Directory Utility:

Directory Utility determines which directory services an OS X computer uses and how it connects to specific directory domains. Directory Utility also defines search policies for finding authentication and contacts information in specific directory domains.

See the Directory Utility Help for more info.
