Mathematica home-use licenses are a benefit of Premier Service for non-student licenses. They are designed to give users who have Mathematica on a work computer the convenience of using it on their home computer as well.
Home-use licenses are valid for the Premier Service subscription period only. When you renew your Premier Service, your home-use license will be extended for another year.
A home-use license through Premier Service is available on your choice of a Macintosh, Windows, or Linux platform regardless of your primary platform–for example, you could have Mathematica for Windows at work and get a home-use license for Macintosh.
To receive your Mathematica home-use license, simply fill out this form.
