- From Wikipedia: Since Mac OS X is based on UNIX, most software packages written for BSD or Linux can be recompiled to run on it. Projects such as Fink, MacPorts and pkgsrc provide pre-compiled or pre-formatted packages.

Mac Os Unix Based
Both macOS—the operating system used on Apple desktop and notebook computers—and Linux are based on the Unix operating system, which was developed at Bell Labs in 1969 by Dennis Ritchie and Ken Thompson. The operating system used on Apple iPhones, now called iOS, is derived from macOS and therefore is also a Unix variant. How to copy disk image on mac.
History of Unix vs. Linux
In 1960, the Massachusetts Institute of Technology, AT&T Bell Labs, and General Electric were working on an experimental operating system called Multiplexed Information and Computing Service or MULTICS. This was designed to run on the GE-645 mainframe computer. But it performed poorly. AT&T Bell Labs called off this project and deployed its resources elsewhere. But Ken Thompson, one of the developers from Bell Labs continued to develop for the GE-645 mainframe, and wrote a game for that computer called Space Travel. But the game was too slow on the GE machine and expensive also, costing $75 per execution. So he re-wrote the game in assembly language for Digital Equipment Corporation's PDP-7 with help from Dennis Ritchie.
This experience, combined with his work on the Multics project, led Thompson to start a new operating system for the PDP-7 and they developed a file system as well as the new multi-tasking operating system itself with the help of a small team of developers. They included a command line interpreter and some small utility programs. This was named as UNICS in 1970, and later change into UNIX.
In 1985, Richard Stallman created the Free Software Foundation and developed the GNU General Public License (GNU GPL), in order to spread software freely. Many of the programs required in an OS (such as libraries, compilers, text editors, a UNIX shell, and a windowing system) were completed by the early 1990s, but few elements such as device drivers, daemons, and the kernel were incomplete. In 1991, Linus Torvalds began to work on MINIX, a Unix-like OS, whose code was freely available under GNU GPL project. Then he developed the first LINUX kernel and released it on 17 September 1991, for the Intel x86 PC systems. This kernel included various system utilities and libraries from the GNU project to create a usable operating system. All underlying source code can be freely modified and used.
Usage of Linux and Unix
Linux OS is great for small- to medium-sized operations, and today it is also used in large enterprises where UNIX was considered previously as the only option. A few years back, Linux was considered as an interesting academic project, but most big enterprises where networking and multiple user computing are the main concerns; people didn't consider Linux as an option. But today, with major software vendors porting their applications to Linux, and as it can be freely distributed, the OS has entered the mainstream as a viable option for Web serving and office applications.
But there are some circumstances where UNIX is the obvious choice, or used to be. If an enterprise used massive symmetric multiprocessing systems, or systems with more than eight CPUs, they needed to run UNIX in the past. Akai eie pro mac high sierra. UNIX was far more capable in handling all the processes more effectively than Linux. However since 2004 more of the world's biggest supercomputers now run Linux than unix. Since 2011 Linux powers over 90% of the top 500 servers. It runs also on the biggest (as of 2011):RIKEN Advanced Institute for Computational ScienceCores: 705024Power: 12659.89 kWMemory: 1410048 GB
Linux - Unix Differences in Cost & Distribution
Linux can be freely distributed, as it is an open Source OS. So anyone can get a copy of Linux from books, magazines, or from the internet also. For server versions, organizations typically pay distributors for a support contract, not the software. The major distributors are RED HAT, Mandrake, and SUSE. How do you download chrome on a mac. For server hardware, IBM, HP, Dell are the major ones.
Unix Or Linux Operating System
UNIX is costly as compared to Linux; the midrange UNIX servers are priced in between $25,000 and $249,999 (including hardware). The major distributors are HP, IBM and SUN. A high end UNIX server can cost up to $500,000. According to IDC, Gartner, IBM is the market leader in UNIX servers, HP is in 2nd position and SUN is in the third position.
Commercial UNIX is usually custom written for each system, making the original cost quite high, whereas Linux has base packages also. In this respect, Linux is closer in its model to Windows than a commercial UNIX OS is. At the time of purchasing a UNIX server, users get a Vendor assistance plan on setting up and configuring the system. But with Linux, Vendor support must be purchased separately.
Threats and Security: Unix vs. Linux
Both of the operating systems are vulnerable to bugs but Linux is far more responsive in dealing with the threats. Linux incorporated many of the same characteristics and functions found in UNIX, including the segmentation of the user domain in a multi-user environment, the isolation of tasks in a multi-tasking environment, a password system that can be encrypted and/or located remotely and much more. As Linux is an open system OS, the bugs can be reported by anyone in the user/developers forum, and within days it can be fixed. But for UNIX, this is not the case, and user has to wait for a while, to get the proper bug fixing patch. The open source community delivers faster because it does not have to go through the endless development cycles of commercial-based operating systems.
At the same time, as an open source operating system, it is supported by tens of thousands of developers worldwide. To reiterate, this allows for better innovation and quicker-to-market features than anything UNIX can provide.
Market and future of Linux and Unix
According to International Data Corp. (IDC).Linux has grown faster than any other server OS over the past few years. Linux user base is estimated to be about more than 25 million machines, compared to 5.5 million for combined UNIX installations.
Linux is gaining popularity because of its application in embedded technologies, free and easily availability. To compete with Linux, vendors such as HP, IBM, Sun are making customized UNIX with graphical user interface and user friendly interface which is also compatible with Linux. The main UNIX vendors--IBM, Sun, and Hewlett-Packard are already putting Linux interoperability features into future releases of AIX, Solaris, and HP-UX.
