I’ve changed the option of my Mac OSX to boot in full 64 bit mode every time it boots and, after that, the NTFS-3G failed to load with an error telling me it’s not able to load MacFuse. This happens because the version of MacFuse include on NTFS-3G do not work on a 64 bit environment and also allowing MacFuse to update to a beta version load the latest official beta (2.1.5) that still do not works on 64 bit.
Only solution I’ve found so far (beside upgrading to the full Tuxera product) was to install a non official build of MacFuse, version 2.1.7.
You can download it here: http://www.phillo.it/MacFUSE-2.1.7.dmg.
Update: Also if the proposed solution worked for smaller files it failed every time with files larger than 200-300 MB. I’ve experimented some more and I’ve not found a suitable solution beside restarting Max OSX in 32 bit mode (booting it keeping the 3 and 2 buttons of the keyboard pressed during the boot process) to copy larger files. The problem seems in the 64 bit part and not on MacFUSE because the I’ve not downgraded MacFUSE from version 2.1.7.
