The Macintosh operating system is credited with having popularized the graphical user interface concept. From 1984 to 2001, starting with System 1 and ending with Mac OS 9. Have you ever wished you could play all the those classic video games on your Mac VICE allows you to do so by executing programs that.The Classic Mac OS ( System Software) is the series of operating systems developed for the Macintosh family of personal computers by Apple Inc.

The last major release of the system was Mac OS 9 in 1999. That program ended after the release of Mac OS 8 in 1997. Apple rebranded the system as Mac OS in 1996, starting officially with version 7.6, due in part to its Macintosh clone program. The name Macintosh System Software came into use in 1987 with System 5. This operating system consisted of the Macintosh Toolbox ROM and the "System Folder", a set of files that were loaded from disk.

Singfasr Mac OS 9 is the ninth and last major release of Apples classic. With the Switcher, the now familiar Clipboard feature allowed cut and paste between the loaded programs across switches including the desktop.On Mac OS 10. The software of each loaded program used the memory exclusively only when activated by the Switcher did the program appear, even the Finder's desktop. With the Macintosh 512K, a system extension called the Switcher was developed to use this additional memory to allow multiple programs to remain loaded. In September 1979, Raskin began looking for an engineer who could put together a prototype. The Macintosh project started in late 1978 with Jef Raskin, who envisioned an easy-to-use, low-cost computer for the average consumer. The name "Classic" that now signifies the historical Mac OS as a whole is a reference to the Classic Environment, a compatibility layer that helped ease the transition to Mac OS X (now macOS). It retained most of the user interface design elements of the classic Mac OS, and there was some overlap of application frameworks for compatibility, but the two operating systems otherwise have completely different origins and architectures.The final updates to Mac OS 9 released in 2001 provided interoperability with Mac OS X. After hearing about the pioneering GUI technology being developed at Xerox PARC from former Xerox employees like Raskin, Jobs negotiated a visit to see the Xerox Alto computer and Smalltalk development tools in exchange for Apple stock options. Jobs and a number of Apple engineers visited Xerox PARC in December 1979, three months after the Lisa and Macintosh projects had begun. This would differentiate it from its contemporaries such as MS-DOS, which use a command-line interface consisting of terse, abbreviated textual commands.In January 1981, Steve Jobs completely took over the Macintosh project. Many basic tasks that required more operating system knowledge on other systems could be accomplished by mouse gestures and graphic controls on a Macintosh. Download oficial gp4 patch v96He was able to conserve precious ROM space by writing routines in assembly language code optimized with "hacks," or clever programming tricks. Much of the original Mac ROM was coded by Andy Hertzfeld, a member of the original Macintosh team. Unlike the IBM PC, which uses 8 kB of system ROM for power-on self-test (POST) and basic input/output system ( BIOS), the Mac ROM is significantly larger (64 kB) and holds key OS code. Apple quickly developed a product named MacWorks, which allowed the Lisa to emulate Macintosh system software through System 3, by which time it had been discontinued as the rebranded Macintosh XL. The Macintosh quickly outsold its more sophisticated but much more expensive predecessor, the Lisa. After its release, the company bought all 39 pages of advertisement space in the 1984 November/December edition of Newsweek magazine. Bruce Horn and Steve Capps wrote the Macintosh Finder, as well as a number of Macintosh system utilities.Apple aggressively advertised their new machine. The icons of the operating system, which represent folders and application software, were designed by Susan Kare, who later designed the icons for Microsoft Windows 3.0. The initial purpose of this is to avoid having the OS use up most of the 128KiB RAM of the initial Macintosh—the initial ROMs were 64KiB. Mac OS 8.1 is the last version that could run on a 68k processor (the 68040).In systems prior to PowerPC G3-based systems, significant parts of the system are stored in physical ROM on the motherboard. As Apple introduced computers with PowerPC hardware, the OS was ported to support this architecture. Files in most file systems used with DOS, Windows, Unix, or other operating systems have only one " fork". An improved file system named HFS Plus ("HFS+" or "Mac OS Extended") was announced in 1997 and implemented in 1998. Both file systems are otherwise compatible. This was quickly replaced in 1985 by the Hierarchical File System (HFS), which had a true directory tree. File systems The Macintosh originally used the Macintosh File System (MFS), a flat file system with only one level of folders. An executable file might consist only of resources (including code segments) with an empty data fork, while a data file might have only a data fork with no resource fork. The resource fork contains other structured data such as menu definitions, graphics, sounds, or code segments that would be incorporated into a program's file format on other systems. The data fork contains the same sort of information as a file in other file systems, such as the text of a document or the bitmaps of an image file.
