After you have purchased your software, you will need to register it to keep it from expiring.
Use this form to obtain a registration number.
You will need to provide the program number and the kind of Mac the software is installed on. Select Register MacWise from the Special Menu to get the program number. The Macintosh type can be found by selecting "About This Mac" from the Apple Menu and then click on More Info. Click on "Hardware" to see the "Machine Name". That is the kind of Mac you have.
If the software was previously installed an a different Mac, we will need to know the kind of Mac it was on. The software must be removed from the old Mac.
Registration is not required for site license versions (site licenses are issued for 10 or more users). Site licenses are pre-registered when they are issued.
