Launching Mathematica on Mac OS X

Launching Mathematica Locally
To run Mathematica using a network license, both the client machine and the license server must be on the network and MathLM must be running.
If you do not have a MathLM license server, you will need to activate your copy of Mathematica. Please see "Activating Mathematica" for more information.

To Launch Mathematica:

Double-click the Mathematica icon in the directory where Mathematica is installed. Alternatively, if you have placed the Mathematica icon in the dock, single-click the icon.

To Launch Only the Mathematica Kernel:

Open the Terminal application and type the full pathname of the MathKernel binary in the window that appears. For example, if you installed Mathematica in the Applications folder, type /Applications/ in a Terminal window and press Return.
