Installing MathType on OS X

As soon as the MathType installation begins on OS X you will be presented with a standard OS X "Authenticate" dialog asking for your password (see below):

MathType for Mac Installation

Enter your user password in this dialog, the one that you chose when you installed OS X or created your user account. Do not enter your MathType registration number in this dialog, or you will receive an 'invalid password' message. Click OK to continue with the MathType installation. You will be prompted for your MathType registration number later.

Many installation programs and OS X itself require administrator authentication to make changes to certain files, folders and system settings. For more information, click the "?" icon in the Authenticate dialog.
