Just noticed that Gestalt was deprecated in 10.8. This makes me sad.

@ccgus As a result, there's no supported API in 10.8 to get the OS version. Also: what else were you still using Gestalt() for!?
Rainer Brockerhoff ‏@rbrockerhoff 13 Sep 2012

@grynspan @ccgus sysctl(3) with the kern.osrelease argument gets you the kernel version, from which you can compute the OS version.

@rbrockerhoff Do you have an algorithm or table?
Rainer Brockerhoff ‏@rbrockerhoff 13 Sep 2012

@mjtsai for all past & current, kern.version returns x.y.z and OS X version will be 10.(x-4).y. Not sure about z though.

@rbrockerhoff @mjtsai @ccgus Aha: And “sw_vers -productVersion” seems to be a documented, command line means of obtaining this.

@danielpunkass @rbrockerhoff @mjtsai @ccgus Sure, but shelling out for something like that is sloppy.
Daniel Jalkut ‏@danielpunkass 13 Sep 2012

@marczak @rbrockerhoff @mjtsai @ccgus I don’t see a non-sloppy solution here, do you? :)

@danielpunkass @marczak @mjtsai @ccgus so what API does sw_vers call...?
