Requirements and additional information:. According to Apple, Snow Leopard will locate any missing drivers on the Web for you. We had no need of any special drivers during our tests. New technologies Apple says a few new technologies in Snow Leopard make it worthy of the upgrade alone, with several features that Apple says will boost performance. Because all new Macs come with bit multicore processors, multiple GBs of RAM, and high-powered graphics processing units, all the major applications in Snow Leopard--including the Finder--have been rewritten in bit to take full advantage of the hardware.
The bit technology allows application developers to allocate more memory to complete tasks so that the software runs faster and more smoothly. Apple has also added what it calls the Grand Central Dispatch that manages data sent to multicore processors in an effort to maximize performance; Apple says the GCD will speed up any application task, from processing images in Photoshop to playing your favorite games. The addition of the GCD also takes away the need for software developers to spend as much time managing multicore processors.
Another new technology in Snow Leopard is OpenCL, which allows software developers to tap into the power of any onboard video cards or GPUs, for graphics processing units for general-purpose computing without the addition of enormous amounts of code. Like the GCD, these are improvements that will mainly affect software developers.
But hopefully it will mean more and better-performing software for users in the future. To put some of these claims to the test, we decided to pit Mac OS X In our anecdotal tests of performance within the Snow Leopard user interface UI , the operating system seems faster and more responsive than with Leopard.
Finder, Stacks, Expose, launching apps, and other everyday processes feel snappy. We didn't, however, notice any improvement in application performance. Overall, we saw only a 2. As this falls within our typical margin of error 5 percent , we saw no significant difference with application performance when moving from Leopard to Snow Leopard. See the bottom of this review for performance charts. Expose, Apple's system for visually finding the window you want on a cluttered desktop, used to be relegated to the Function keys on your keyboard.
Snow Leopard now makes Expose accessible from the Dock; just click and hold on a Dock icon to see thumbnails of all the open windows in that application.
