MagicNTFS mounts the windows ntfs bootcamp disk writeable (rw). So it‘s very easy to copy and transfer files between Mac OS X and Windows bootcamp on a mac. This tool works only temporary. After a reboot, the bootcamp disk is readonly again. It does not change the fstab. Please if you are asked to enter the password, enter it twice.
Note: MagicNTFS is no longer under development, and it is no longer available for sale.
