Troubleshooting on Mac OS X
If the front end password dialog box appears when you launch Mathematica
, either Mathematica
could not locate the mathpass file or there was no valid password in the mathpass file. To resolve this problem, first check that there is a mathpass file in one of these directories: /Library/Mathematica/Licensing, $InstallationDirectory
/Configuration/Licensing, or ~/Library/Mathematica/Licensing. To find the exact location of $InstallationDirectory
on your machine, evaluate the command $InstallationDirectory
in a notebook. If you did not find a mathpass file in these locations, follow the instructions in "Entering a Single-Machine Password"
to re-enter your password.
If there is a mathpass file in one of those directories, the password or passwords are invalid. Make sure that your MathID number matches the MathID number used to issue your password. If your MathID number changes, you will need to contact Customer Service to get a new password. Contact information is provided in "Registration and Passwords"
Front End Preferences
Front end preferences, such as the locations of recently opened and saved files, are stored in a front end initialization file called init.m
. This file is located in the directory ~/Library/Mathematica/FrontEnd. If you need to reset the front end preferences to their default values, hold down Shift+Option
during startup. This will cause the initialization file to be rebuilt automatically.
Information about your Mathematica
system layout, such as the locations of text resource files and Help Browser files, is stored in caches. These caches are located in the directory ~/Library/Mathematica/FrontEnd/6.0\ Caches.
A corrupted cache may cause the front end to produce an error or quit immediately on startup. The most convenient way to restore the caches to their default values is to hold down Shift+Option
during startup. This will cause the Mathematica
caches and the initialization file to be rebuilt automatically.
If you want to rebuild your caches but retain your preferences, hold down Shift
during startup. This will delete and rebuild the cache without rebuilding your front end initialization file.
