Snow Leopard's Boot Camp Includes HFS+ Windows Drivers
Boot Camp is Apple's software package that allows customers to boot Microsoft's Windows operating system on their Intel Macs. The Boot Camp package includes the necessary Windows drivers to support each Mac's hardware. Windows, however, does not routinely recognize Mac formatted hard drives and is unable to read or write to them without special drivers. The newest version of Snow Leopard's Boot Camp appears to include these special drivers to allow read access to Mac data even under Windows.
The move should make it easier for customers to switch between Windows and Mac operating systems by allowing files to be more easily transfered back and forth. Up until now, customers would have to rely on third-party utilities such as Mediafour's MacDrive to accomplish the same task.
