Fortunately, the developers released a Mac OS version for SPSS. But, like the Windows version, it was released as a shareware version. You can download a demo version on the Mac Informer application's page, and also you can download it directly from the developer official page. After the downloading is complete, open the setup file that was downloaded and start installation process. Follow the steps and in only a few moments you will have your SPSS application installed on your computer. Moreover, this demo version comes with some limitations. Therefore, if you want a full featured application you will need to buy it.
