For mainstream computer users doing typical tasks, Apple Computer's Macintosh models have huge advantages over the prevalent Windows computers from companies such as Dell and Hewlett-Packard. The Macs have sleeker hardware designs, a superior operating system, much better built-in software, and virtually no exposure to viruses and spyware. Apple's flagship model, the iMac, is the best consumer desktop on the market.
There's a big barrier for Windows users tempted to switch to the Mac: software. While there are thousands of programs for the Mac's operating system, called OS X, potential Mac buyers often find they have one or two Windows programs they must use that have no Mac equivalent. These range from custom software required by their employers, to niche programs for specific industries or hobbies, to games.Yesterday, Apple took a historic, and potentially huge, step to remove that obstacle to switching. It introduced free software that makes it easy to install and run Windows on the latest Mac models as a complement to the Mac operating system. With this new software, called Boot Camp, you can turn your Mac into a fast, full-fledged Windows computer for those occasions when you must run a Windows program. That makes the iMac, the Mac Mini and the MacBook Pro laptop the only computers in the world that allow mainstream users to run both operating systems at full speed.
Boot Camp (downloadable at www.apple.com/macosx/bootcamp absolutely for free) allows you to "boot up," or start up, the Mac in either operating system. You can designate which one gets loaded when the machine boots up. Or, by simply holding down the Option (or Alt) key while starting or restarting the computer, you get a screen showing icons for the two operating systems. Click on the Mac icon and the machine runs the Mac OS. Click on the Windows icon and it runs Windows.
Each operating system gets its own dedicated portion, or "partition," of the Mac's hard disk, so they don't interfere with one another. Programs you install in each operating system, and files you create with them, are stored in the part of the hard disk devoted to that operating system.
All of this is possible because the latest Macs use the same Intel chips as Windows machines. Boot Camp runs only on these new Intel-based Macs, which have been available since January. Older Macs can also run Windows, in a fashion, but only via a clumsy Microsoft program that creates a painfully slow "virtual" Windows computer that can't handle some demanding programs, like games. By contrast, with Boot Camp, the new Intel-based Macs can become true, fast, full-fledged Windows computers that are essentially identical to standard Windows computers, yet still retain the ability to operate as normal Macs.With Boot Camp, you could choose to run a Mac solely as a Windows machine, with good results. But Apple doesn't expect many people to do this. Instead, it assumes Boot Camp users will still use the Mac operating system and Mac software 90% of the time, switching into Windows mode only to run a few Windows programs.
