The use of Intel processors and the development of Boot Camp have both helped Apple sharply increase marketshare after years of slight decline, giving switchers the option to continue running Windows-only applications as they transition to MacOS X. A consistent requirement of Boot Camp and other multi-OS solutions, however, is that owners must have a stand-alone copy of Windows to install. Codeweavers' newly released beta of CrossOver for Mac eliminates this requirement, allowing emulation of Windows programs without installing Windows itself. The 60-day free test version currently runs a limited selection of Windows software with a compatibility list receiving periodic updates as new programs are verified. CrossOver currently supports any Intel-based Mac.
