The first Intel Macs shipped with either an Intel Core Duo or Core Solo chip, both of them 32-bit processors. That's because not all Intel Macs have 64-bit processors. It's worth noting that not all Intel Macs can make use of 64-bit processing. (MacBook Air owners can use a DVD drive in another computer, provided they turn on CD/DVD sharing.) You'll also need a DVD drive for installation. If your processor is a PowerPC, you're out of luck if it's from Intel, you're good to go.)Īny Intel Mac will run Snow Leopard, provided it has at least 1GB of RAM (though 2GB or more will deliver better performance) and 5GB of hard drive space. (Not sure what you have? Click the Apple menu and choose About This Mac. The most important question to answer before upgrading to Snow Leopard is whether your Mac can handle it. Here's what you need to know about the upgrade process - which in itself illustrates both UI improvements and under-the-hood advances over past versions of Mac OS X. In Snow Leopard, Apple focused on making the OS run faster using technologies like Grand Central Dispatch (which allows a Mac with a multi-core processor to more effectively distribute work among cores) and OpenCL (which allows a Mac's graphics processors to be used for general computing tasks whenever possible), and making all the core system applications and most core components 64-bit.īut before you can appreciate Snow Leopard's performance, user interface refinements, and technology tweaks, you have to get it installed. That contrasts with its predecessor, Leopard (Mac OS X 10.5), which added more than 300 new features when it was released two years ago. In building Snow Leopard, the latest version of Mac OS X (version 10.6), Apple focused more on under-the-hood improvements to boost speed and stability than on adding new features.
