1. The similarities between Mac OS X and Linux are highly similar, and therefore there are minimal hardware requirement differences between them. The main difference is that Mac OS X is proprietary, which means that there are only a limited number of drivers recognized by Mac OS X. Similarly, Apple often requires minimum hardware requirements for its latest version of its OS, so current version of Mac OS X will be limited to newer hardware, such as faster processors and more RAM, while Linux is more customizable.
2. Research reveals that Mac OS X and Linux are highly similar, with the major difference being that Linux is open-sourced, while Mac OS X is proprietary. Mac OS X is therefore an optimized version of Linux designed to run specifically on Apple devices. The reason the two are very similar is because they are both used on an older OS, Unix, which provides the central framework for which the two operating systems were developed. Because they share much of the same design of a common OS, they have evolved to be very similar today.
3. Because Linux is open-sourced, while both Windows and Mac OS X are not, the main disadvantage of using Linux are security threats that can exploit the OS. While these exploits can also be found in Microsoft and Apple operating systems, there is more testing and quicker response to threats to both Windows or OS X. On the other hand, Linux is much more customizable, and can be specifically tailored for specific tasks or functions. While the average user might prefer the more consumer-friendly experience of Windows or OS X, a small-business or individual who needs to tailor a computer for a specific function not normally utilized by an average user, would most likely benefit from the customizability of Linux.
