Mac OS, while it is based on a Unix-like structure (specifically, it's derived from BSD), is not typically referred to as a "Unix flavor" in the same way that BSD, AIX, and IRIX are. These are direct derivatives or versions of Unix, whereas Mac OS (especially modern versions, known as macOS) is a commercial operating system developed by Apple Inc. that incorporates elements from Unix but also includes proprietary components.
