Third-party software like Paragon’s NTFS or the free NTFS-3G driver enabled read/write support, but a native solution was more desirable. Individual files often require conversion, but what about whole disks? Apple has long supported the universal and simplistic FAT filesystem, and added read-only support for NTFS back in 2003 in OS X 10.3 “Panther”. One of the daily hassles of using Apple Macintosh computers is the incompatibilities that arise with the broad Microsoft Windows world.
