osx - Which version of OS X should my program target? -


We are creating an application for OS X, and we do not trust all users who have upgraded Snow Leopard , Or whatever is the latest version, we want to make sure that as many people as possible can use our app, but we do not want to throw some of the improvements made in the OS X version, if only 1 % Of users before versions Is stuck using.

Anywhere can I find information about the proportion of those people who are using each version of OS? Or is there some "common sense" on this matter that real Mac developers know?

We do not need any superficial graphics or 3D animation stuff, just plain old windowing API - but we already have a problem where "NSStreamDelegate" is not supported before Snow Leopard.

Thank you!
