What are the system requirements to support SmartZipperPro?
According to the information on the Mac App Store, the software requires OS X 10.6 or later and a 64-bit processor. I've installed the software on various OSX versions like 10.6, 10.7, 10.8 and 10.10 and it worked normally without errors.
You can download a trial version through the official website to make sure that it works with your OSX version: http://www.totalrar.com/SmartZipperTrial/SmartZipperPro.dmg
