Testing the Installation on Mac OS X

The following simple commands allow you to test the installation of Mathematica. Running these commands does not guarantee that the installation was successful, but a failed command can indicate that a serious problem occurred during installation.
You should run these tests from a regular user account and not from an account with administrator privileges.
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 run into problems when doing these tests, see the troubleshooting tips in "Troubleshooting on Mac OS X". If you do not find the answer there, check the Technical Support website at

To Test the Kernel:

1.  To start the 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.
2.  Type N[Pi, 20] and press Return. The number in the output should match the output shown here.
3.  To exit the kernel, type Exit and press Return.

To Test the Front End:

1.  Launch Mathematica by double-clicking the Mathematica icon. Three windows appear.
2.  Click anywhere inside the leftmost empty window. This window is a Mathematica notebook.
3.  Press the Esc key. You should see three small horizontal lines in a column (). Type int and press Esc again. You should see an integral sign ( ). As an additional font check, typing \[CheckmarkedBox] and \[CirclePlus] should print the symbols and , respectively. If the symbols show up correctly, the fonts have been properly installed.
4.  From the Help menu, choose Documentation Center. The Mathematica Documentation Center should appear.
