Talk:List of Mac OS versions/@comment-72.219.167.64-20141204200526

As a developer I strongly recommend that you use an operating system that is within the generation of your hardware. Usually, with the exception of some earlier system 7 machines that require a specific OS (which are hardly in use these days anyway) your best bet would be to use the latest OS for your generation Mac. In most case, with only a few exceptions due to firmware on optical superdrives in older powerbooks, the OS will operate satisfactorily in the same generation machine. This may be obvious to most of us power users, but to some that are pioneering in thier learning methods by trial and error, it may not be. Lastly, I advise to not attempt applying OS X to any machine originally developed for system 7 and before. The subroutines have different call points and your proccessing will in most cases be incomplete. If you have an old machine like that, hang it on a wall or donate it to a museam. Good Day!
