The Mac operating system, starting with OS X, was built to run on a Unix kernel.

OS X (now known as macOS) is based on a Unix-like operating system known as Darwin, which incorporates the Mach kernel. This foundation provides robust multitasking, security, and compatibility with various Unix tools and software. The choice of a Unix-based system aligns with Apple’s goals to create a stable and secure operating environment, as Unix has been known for its strong networking capabilities and reliability over the years.

In conclusion, the correct answer to the question is Unix, as this reflects the underlying architecture of the Mac operating system from its initial OS X version onwards.
