Tiger, moving towards 64-bit

Apple's next operating system, Mac OS X Tiger, will break the limitations of 32-bit computing and allows developers to create command-line applications, servers, and computation engines that can work with more than 4GB limitation of memory usage. Not just that, there will be no compromise in the ability to run current 32-bit applications.

By definition, the difference between 32-bit computing, the gold standard for the last 20 years of desktop computing, and 64-bit computing is the size of the memory space an application can use. In a 32-bit world, an application can address 4GB of memory. For many of the applications that we use everyday, such as word processors and spreadsheets, this is more than enough memory. However, if you work with large datasets, such as the human genome or geospatial data, 4GB suddenly becomes very limiting.

64-bit computing shatters the 4GB limit giving a virtual address space in excess of 16 exabytes. That's 16 billion billion bytes. You can't even begin to put that much RAM in a Power Mac—yet—but Tiger sets the stage for some truly incredible system capabilities.
