Mac OS X version Leopard was released on 26 Oct , and was available in 2 variants: a desktop version and a server version.

Mac OS X Tiger added limited support for bit applications on machines with bit processors; Leopard extended the support for bit applications to include applications using most of Mac OS X's libraries and frameworks. In addition, the Mac OS X kernel has been rebuilt to run in bit mode on some machines.

Newer Xserve and Mac Pro machines will run a bit kernel by default; newer iMac and MacBook Pro machines can run a bit kernel, but will not do so by default.

Stuart Harris, software product marketing manager at Apple Australia, said, "For the most part, everything that they experience on the Mac, from the bit point of view, the applications, the operating system, is all going to be bit, but that at this stage there were very few things, such as device drivers, that required bit mode at the kernel level". With some tweaking, the Unibody MacBook can be set to boot the bit kernel. Grand Central Dispatch uses the multiple processor cores now in every new Macintosh for more efficient performance.

Due to the technical difficulties traditionally involved in making applications optimized for multicore CPUs, the majority of computer applications do not effectively use multiple processor cores. Grand Central Dispatch includes APIs to help programmers efficiently use these cores for parallel programming.

Grand Central Dispatch shifts thread handling focus to itself rather than leaving it to specific applications to distribute jobs evenly across cores and clears up unused memory created by inactive or old threads to achieve maximum performance. Apple is also releasing APIs for Grand Central Dispatch for developers to use in their applications and also to analyze specific blocks of code running on Grand Central Dispatch.

A new C and Objective-C language feature named " Blocks " facilitates creation of code that will easily optimize to take advantage of Grand Central Dispatch. OpenCL Open Computing Language addresses the power of graphics processing units GPUs to leverage them in any application, and not just for graphics-intensive applications like 3D games. OpenCL automatically optimizes for the kind of graphics processor in the Mac, adjusting itself to the available processing power.

OpenCL provides consistent numeric precision and accuracy, fixing a problem that has hampered GPU-based programming in the past.

Only the most process intensive parts of the application need to be written in OpenCL C without affecting the rest of the code. CUPS the printing system used in many Unix-like operating systems has been updated to version 1. CUPS 1.
