However, it’s important to note that while macOS updates are free, the initial purchase of a Mac computer includes the cost of the operating system.

Is macOS based on Linux?

No, macOS is not based on Linux. macOS, formerly known as Mac OS X, is based on the Unix operating system. It is specifically the BSD (Berkeley Software Distribution) variant of Unix.

While both macOS and Linux share some similarities due to their Unix heritage, they are distinct operating systems with different architectures, kernels, and user interfaces. Linux, on the other hand, is an open-source operating system kernel that forms the basis for various Linux distributions (distros), which are typically developed and maintained by the open-source community.
