• C:\Users\<user>\AppData\Roaming\Mathematica
• C:\Users\<user>\AppData\Local\Wolfram
• C:\Users\<user>\AppData\Roaming\Wolfram
• C:\Users\<user>\AppData\Local\Mathematica

… where <user> is your username on the computer.

These folders may be hidden on your computer. You may need to enable your account to see hidden files and folders.

Close Mathematica, then delete or rename all these directories in order to reset Mathematica to its default configuration. Mathematica will recreate these directories the next time you start the software.

macOS

By default, the Base Directory, the User Base Directory, the Local Base directory and the Cache Base Directory are located at:

• /Library/Mathematica
• ~/Library/Mathematica
• ~/Library/Caches/Wolfram
• ~/Library/Wolfram

These folders may be hidden on your computer. To navigate to a hidden folder, open the Finder application. Press Command + Shift + G to open a file search dialog and enter “~/Library/Mathematica/”. Finder opens the hidden folder.

Close Mathematica, then delete or rename all these directories in order to reset Mathematica to its default configuration. Mathematica will recreate these directories the next time you start the software.
