The family of Macintosh operating systems developed by Apple Inc. The system, rebranded "Mac OS" systemwas preinstalled on every Operating until 2010 offered on Mini clones microsoft office 2010 for mac trial a short time in the s. Noted for its ease of use, it was also mac for its lack of modern for compared to its competitors. The current macOS is preinstalled with every Mac and is updated annually. Apple's effort to expand upon and develop a replacement for its classic Mac OS in the s led to a few cancelled projects, code named Star TrekTaligentand Copland. Although they have different architectures, the Macintosh operating systems share a common set of GUI principles, including a menu bar across the top of the screen; the Finder shellfeaturing a desktop metaphor that represents files and applications using icons and relates concepts like directories and file deletion to real-world objects like folders and a trash can ; and overlapping windows for multitasking. The "classic" Mac OS is the original Macintosh operating system that was introduced in alongside the first Macintosh and remained in primary use on Macs through
The first desktop version of the system was mino on March 24,supporting the Aqua user interface. Since then, several more versions adding newer features and technologies have been released.
Sincenew releases have been offered on an annual basis. An early server computing version of the system was released in as a technology preview.

It was followed by fpr more official server-based releases. Server functionality has instead been offered as an add-on for ffor desktop system since Operatig idea was to offer a single "overdesigned" hardware platform on which third-party vendors could build practically any product, reducing the otherwise heavy workload of developing a NuBus -based expansion card.
The first version of the system was ready for use in February It was not very competitive for its time, due in part to the crowded Unix market and Macintosh hardware lacking high-end design features present on workstation -class computers. The Macintosh Application Environment MAE was a software package introduced by Apple in that allowed users of certain Unix -based computer workstations to run Apple Macintosh application software.
The last version, MAE 3. It was discontinued on May 14, In mid operxting, the community-led MkLinux Developers Association took over development of the operating system. MkLinux is short for "Microkernel Linux," which refers to the project's adaptation of the Linux kernel to run as a server hosted atop the Mach microkernel.
MkLinux is based on version 3.
Star Trek as in "to boldly go where no Mac has gone before" was a relatively unknown secret prototype beginning inwhose goal was to create a version of the classic Mac OS that would run on Intel -compatible x86 personal computers.
A team consisting of four from Apple and four from Novell was able to get the Macintosh Finder and some basic applications such as QuickTimerunning smoothly on the x86 architecture. The project was canceled a year later in earlybut some of the code was later reused when porting the Mac OS to PowerPC. Taligent a portmanteau of "talent" and "intelligent" was the name of an object-oriented operating system and the company dedicated to producing it.
The development process never worked, and Taligent is often cited as an example of a project death march. Apple pulled out of the project in before the code had been delivered.
Copland was a project at Apple to create an updated version of the classic Mac OS. It was to have introduced protected memorypreemptive multitasking and a number of new underlying operating system features, yet still be compatible with existing Mac software.
As originally planned, a follow-up release known as "Gershwin" would add multithreading and other advanced features. New features were added more rapidly than they could be completed, and the completion date slipped into the future with no sign of a release.
InApple decided to cancel the project outright and find a suitable third-party system to replace it. Apple also developed the Newton OS for its Newton personal digital assistant from to From Wikipedia, the free encyclopedia.
