If you’re trying to upgrade SPSS on a Macintosh running OS X.x, try one of the following:
SPSS 10 License Upgrade on a Macintosh
SPSS 11 License Upgrade on a Macintosh
The License Renewal utility also ships on the SPSS 11 CD-ROM. Insert the SPSS 11 CD into your Macintosh and once mounted you will find the License Renewal Utility in the SPSS 11 volume. Double click on this License Renewal Utility and you will be prompted for the new license code. Click on the ‘Update’ button to check the status of the new license code or you can click on the ‘OK’ button to apply the new license code to your SPSS 11 for Mac OS X installation.
