Tuxera NTFS, one of several drivers designed to enable full NTFS support on Macs, has updated their version with full 64-bit support, included extended attributes, and a simpler install process. The new features are specifically aimed at users of mid-August (2010) Mac Pros -- the first to have Snow Leopard's 64-bit kernel run as the default -- though the driver is useable in both 32-bit and 64-bit environments.
