	Mac OS memory management - Wikipedia, the free encyclopedia
		System 7 was the first version of the OS able to address more than 8MB on models equipped with complete 32-bit processors (Motorola 68020, 68030 and 68040), and featured a "32-bit clean" memory manager and replacement techniques for all those areas that previously used the high address bits.
		While the Mac OS memory model, with all its inherent problems, remained this way right through to Mac OS 9, due to severe application compatibility constraints, the increasing availability of cheap RAM meant that by and large most users could upgrade their way out of a corner.
		Mac OS X finally does away with the whole scheme, implementing a modern sparse virtual memory scheme.

	Mac OS - Wikipedia, the free encyclopedia
		Mac OS, which stands for Macintosh Operating System, is a range of graphical user interface-based operating systems developed by Apple Computer for their Macintosh computers.
		System 7.5.1 was the first to include the Mac OS logo (a blue variation of a smiley face), and Mac OS 7.6 was the first to be named "Mac OS" (to ensure that users would still identify it with Apple, even when used in "clones" from other companies).
		Mac OS X brought Unix-style memory management and pre-emptive multitasking to the Mac platform.

		Mac OS 7.6 (which debuted in 1996) was the first to be named Mac OS because of the appearance of Mac "clones", workalikes from other companies such as Power Computing and Motorola, and Apple wanted to make it clear that the operating system was its own intellectual property.
		It is also the second Mac OS to include a command line (the first is the now-discontinued A/UX, which supported classic Mac OS applications on top of a UNIX kernel), although it is never seen unless the user launches a "terminal" program.
		Mac OS X has a compatibility layer for running older Mac applications, the Classic Environment (known to programmers as "the blue box").

	Mac OS X - Wikipedia, the free encyclopedia
		Mac OS X is based on the Mach kernel and the BSD implementation of Unix, which were incorporated into NEXTSTEP, the object-oriented operating system developed by Steve Jobs's NeXT company after he was forced from Apple in 1985.
		Mac OS X v10.2 was never officially referred to as Jaguar in the United Kingdom due to an agreement with the automobile manufacturer Jaguar, although boxes and CDs still bore the Jaguar-skin logo.
		Mac OS X v10.4 "Tiger" was released on April 29, 2005.

	An Overview of Memory Usage (Site not responding. Last check: 2007-10-25)
		Memory usage in Mac OS X is drastically different from memory usage in the Classic Mac OS, largely because of the UNIX underpinnings.
		Mac OS X's performance drops when all available memory is used, because it has to start removing things from memory ("paging out"), which has a performance hit.
		Memory Usage Getter displays the memory usage of background UNIX processes, and allows the user to sort the processes that he is running into two tabs, for easy viewing, with a third reserved for system processes.

	The Memory Management Reference: Memory management in Mac OS
		Mac OS has a flat address space, shared between all processes.
		Mac OS supports a form of relocatable heap block, which is accessed indirectly via a handle which points into a master pointer block (a non-relocatable heap block).
		It is important to note that, on the 68k, the Mac OS Memory Manager is inefficient for large numbers of allocations.

		Mac OS X implements a "unified buffer cache", meaning that the buffer cache and the virtual memory system are combined.
		Mac OS X provides the window server with fast access to pixels by making all windows "buffered." All the pixels of a buffered window are stored in in memory.
		And since Mac OS X uses individual swap files (rather than a dedicated swap file system), a separate swap partition is only likely to make a significant difference if the previous swap files were heavily fragmented on disk.

		The more you have, the happier OS X is. And the more you demand of your Mac (I've got 13 applications running and, according to Process Viewer, 76 active processes right this second), the more more RAM will speed things up.
		With Mac OS 9, when you ran short of RAM, your Mac would scold you and tell you there wasn't enough of the stuff to do whatever it was you were trying to do-usually launch a program.
		In Mac OS X, memory management is a whole new ball of wax.

	Apple - Mac OS X - UNIX
		Beneath the surface of Mac OS X lies an industrial-strength UNIX foundation hard at work to ensure that your computing experience remains free of system crashes and compromised performance.
		All of the standard UNIX utilities and scripting languages are included in Mac OS X: editors such as emacs, vim and even ed; file management tools such as cp, mv, ls and tar; shell scripts including bash (the default shell), tcsh (csh) and zsh.
		Since Mac OS X rarely requires you to reboot, you’ll hardly ever notice it, but Tiger takes less time to start up, thanks to launchd.

	The Need for a New OS (Site not responding. Last check: 2007-10-25)
		The original Macintosh lacked a memory management unit — a microchip that specifically controls all memory use in the computer, so a lot of memory management features were missing.
		The Mac OS' implementation of Virtual Memory was slow, and still had a built-in limit on the amount of memory available, instead of being able to use as much disk space as was available.
		Programs had to be loaded into a continuous block of memory, as users opened and closed programs in the normal use of the computer, the free memory space could become fragmented — little pieces of unused memory spaces scattered here and there.

		Although it may seem counter-intuitive, most experienced Mac users revel in their ability to micro-manage their environment.
		They expect nothing less than direct manipulation from their interface, and anything that gets in the way of their ability to customize their environment (within reasonable bounds) is seen as damage.

		I'm porting some C code from Windows to Mac OS X. Earlier the same code has been ported to Mac OS 9, and in that version, C commands like calloc, fopen etc. have been replaced with some Mac specific calls.
		Now is it so that I have to use those Mac specific calls, in Mac OS X, too, or is it possible to drop them off (which would ease my job considerably)?
		As far as I recall (and I recall this one well) they were available to use in Mac OS 9 and yes, they indeed work in Mac OS X. Back to top
