I can't load my PrintMaster 2012 application on MacBook Pro with Mac OS X 10.9.1. Mavericks. Are these two compatible?
It seems that the latest version of the PrintMaster Platinum, the version 6, is fully compatible with Mac OS X Mavericks. I recommend you to upgrade your software to the latest version in order to use it on your Mac. You can download the latest version from the official website.
