The world of operating systems can be complex and confusing, especially when it comes to understanding the underlying architecture of popular platforms like macOS. As a user, you might have wondered whether macOS is based on Linux or Unix. In this article, we’ll delve into the history of macOS, explore its roots, and provide a clear answer to this question.
A Brief History of macOS
To understand the relationship between macOS and Unix/Linux, let’s take a step back and look at the history of macOS. The first version of macOS, then called Mac OS X, was released in 2001. It was a significant departure from the classic Mac OS, which was a proprietary operating system developed by Apple.
Mac OS X was built on top of a Unix-based foundation, which was a deliberate design choice by Apple. The company wanted to create a more stable and secure operating system, and Unix provided the perfect foundation. The Unix-based core of Mac OS X was called Darwin, which was an open-source operating system developed by Apple.
The Role of NeXT in macOS Development
To understand the Unix roots of macOS, we need to look at the role of NeXT in its development. NeXT was a company founded by Steve Jobs in 1985, after he left Apple. NeXT developed a Unix-based operating system called NeXTSTEP, which was used in their line of workstations.
When Apple acquired NeXT in 1996, they also acquired the rights to NeXTSTEP. The NeXTSTEP operating system became the foundation for Mac OS X, and its Unix-based architecture played a significant role in shaping the future of macOS.
Unix vs. Linux: What’s the Difference?
Before we dive deeper into the relationship between macOS and Unix/Linux, let’s clarify the difference between these two terms.
Unix is a multi-user, multi-tasking operating system that was first developed in the 1970s. It’s a proprietary operating system, and its source code is not publicly available. Unix is known for its stability, security, and scalability, making it a popular choice for servers and mainframes.
Linux, on the other hand, is an open-source operating system that was developed in the 1990s. It’s based on the Unix architecture and is designed to be compatible with Unix applications. Linux is free to use, modify, and distribute, making it a popular choice for developers and users alike.
Is macOS Unix or Linux?
Now that we’ve clarified the difference between Unix and Linux, let’s answer the question: is macOS Unix or Linux?
macOS is based on a Unix foundation, but it’s not Linux. The Darwin core of macOS is a Unix-based operating system, but it’s not open-source like Linux. While macOS shares many similarities with Linux, it’s a proprietary operating system developed by Apple.
In fact, macOS is certified as a Unix operating system by The Open Group, a non-profit organization that owns the Unix trademark. This certification ensures that macOS meets the standards set by The Open Group for a Unix operating system.
