After more than 20 years (DOS and any version of Windows) I made the switch, in the expectation that some will go wrong, and (as usual under Windows) problems. None of the expected problems was true, it was frightening how smoothly the transition worked on Mac OS. In conjunction with Parallels also appropriate Windows programs can still be used. Again, ran from the installation of the data acquisition from the Windows machine to hardware detection (USB / iPhone / external hard drives / color laser printer / MFC Brother) completely smoothly. Even mistakes on the old machine are suddenly in the configuration, installation and during the execution of the W7-programs no longer an issue. I would not hesitate to buy the program again and angry today, have not previously ventured the transition.
