Mac OS X operating system

Since only the 10.0 to 10.1 was free upgrade (the others you have to buy), there's separate tags for each "major" version of OS X.

OS X is written in Objective-C, the Kernel is pure C language (the kernel is based on BSD and the Mach kernel which are both C). Some subsystems are written in C++ but great care is taken to not expose the C++ code to the C and Objective-C compilers that the core of OS X so OS X is not written C++.
