If there is another sub I should check out please point me in the right direction. If anyone knows of a nice USB controller that would be helpful as well. I have an old Mac Mini that Id love to turn into an intro-video game system for my 4 year old son. Im looking for a good NES/SNES/SEGA/Whatever emulator for OS X.

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. As part of an agreement allowing Xerox to buy shares in Apple at a favorable price, it also used concepts from the Xerox PARC Alto computer, which former Apple CEO Steve Jobs and other Lisa team members had previewed. The first version of the system software, which had no official name, was partially based on the Lisa OS, which Apple previously released for the Lisa computer in 1983. Apple released the original Macintosh on January 24, 1984. Clone or download this repo.

Mac users stress no more Introducing the most extensive and cleanest Mac emulators section available on the net Recommended: OpenEmu All-in-one emulator for Mac (Requires OS X Initial versions of the System Software ran one application at a time. 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.

By the mid-1990s, however, contemporary operating systems such as Windows NT, OS/2, and NeXTSTEP had all brought pre-emptive multitasking, protected memory, access controls, and multi-user capabilities to desktop computers, The Macintosh's limited memory management and susceptibility to conflicts among extensions that provide additional functionality, such as networking or support for a particular device, led to significant criticism of the operating system, and was a factor in Apple's declining market share at the time.After two aborted attempts at creating a successor to the Macintosh System Software called Taligent and Copland, and a four-year development effort spearheaded by Steve Jobs's return to Apple in 1997, Apple replaced Mac OS with a new operating system in 2001 named Mac OS X the X signifying the underlying Unix system family base shared with Jobs's development of the NeXTSTEP operating systems on the NeXT computer. With the Switcher, the now familiar Clipboard feature allowed cut and paste between the loaded programs across switches including the desktop.With the introduction of System 5, a cooperative multitasking extension called MultiFinder was added, which allowed content in windows of each program to remain in a layered view over the desktop, and was later integrated into System 7 as part of the operating system along with support for virtual memory. 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.

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).

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.

In addition to the ROM, he also coded the kernel, the Macintosh Toolbox, and some of the desktop accessories (DAs). He 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. The final Lisa and Macintosh operating systems use concepts from the Xerox Alto, but many elements of the graphical user interface were created by Apple including the menu bar, pull-down menus, and the concepts of drag and drop and direct manipulation.

As Apple introduced computers with PowerPC hardware, the OS was ported to support this architecture. Many of Lisa's operating system advances would not appear in the Macintosh operating system until System 7 or later.Architecture Compatibility Early versions of Mac OS are compatible only with Motorola 68000-family Macintoshes. 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.

To provide such niceties at a low level, early Mac OS depends on core system software in ROM on the motherboard, which also ensured that only Apple computers or licensed clones (with the copyright-protected ROMs from Apple) can run Mac OS.Several computer manufacturers over the years made Macintosh clones that were capable of running Mac OS. This is in contrast to MS-DOS and CP/M computers of the time, which display such messages in a mono-spaced font on a black background, and require the use of the keyboard rather than a mouse, for input. This architecture also allows for a completely graphical OS interface at the lowest level without the need for a text-only console or command-line mode: boot time errors, such as finding no functioning disk drives, are communicated to the user graphically, usually with an icon or the distinctive Chicago bitmap font and a Chime of Death or a series of beeps. The initial purpose of this is to avoid having the OS use up most of the 128KiB RAM of the initial MacintoshвЂ”the initial ROMs were 64KiB.

File systems The Macintosh originally used the Macintosh File System (MFS), a flat file system with only one level of folders. These changes were made to disassociate the operating system from Apple's own Macintosh models. Steve Jobs ended the clone-licensing program after returning to Apple in 1997.Support for Macintosh clones was first exhibited in System 7.5.1, which was the first version to include the 'Mac OS' logo (a variation on the original Happy Mac startup icon), and Mac OS 7.6 was the first to be named 'Mac OS' instead of 'System'. These machines normally ran various versions of classic Mac OS.

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. By contrast, MFS and HFS give files two different 'forks'. 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.
