Mac Users can run PTF PRO in Bootcamp running Windows 7 or above, or in Parallels.
Parallels can be found here: http://www.parallels.com/au/products/desktop/?utm_source=bing&utm_medium=cpc and offer a free trial.
Bootcamp can be found here: https://www.apple.com/support/bootcamp/
Either should be fine in running PTF PRO on iOS.
