Systemwide Defaults on Mac OS X

If you have installed Mathematica in a location where multiple users run it (for example, on a file server or multi-user machine), then you can set up systemwide defaults for the Mathematica front end and kernel. This is ideal for setting up Mathematica for use in computer labs and classrooms. If you share the directory $BaseDirectory across the network, these defaults will also take effect on local installations that use the shared $BaseDirectory.
The following instructions assume that $BaseDirectory and $UserBaseDirectory have their default values, /Library/Mathematica and ~/Library/Mathematica, respectively.

To Set Up a Configuration File for the Front End:

1.  Launch Mathematica, and set up any changes to the front end that you need. For example, you may want to modify default file locations, language options, or menu settings.
2.  Quit Mathematica.
3.  Copy the file ~/Library/Mathematica/FrontEnd/init.m to the directory /Library/Mathematica/FrontEnd.
These settings will now be used by the front end unless overridden by the local init.m file stored in the user's ~/Library/Mathematica/FrontEnd directory.

To Set Up a Configuration File for the Kernel:

1.  Launch Mathematica, and create a new file.
2.  Add any Mathematica commands that should be evaluated on startup. For example, you may want to add a function definition or display a message at startup. Enter all the commands in the same cell, separating commands with semicolons.
3.  Make this cell an initialization cell by selecting the cell bracket and then choosing CellCell PropertiesInitialization Cell.
4.  When you have finished making your changes, choose FileSave and select Mathematica Package from the Save as type pop-up menu. Then save the file as /Library/Mathematica/Kernel/init.m.
These commands will be evaluated when users launch Mathematica. If you added a function definition, that function will be available to all users.
