Was having problems swapping an external hard drive between Windows 7 and Mac OSX. NTFS is a proprietary Microsoft format. Here’s how to solve the problem:
- Get MacFUSE and install on OSX: http://code.google.com/p/macfuse/
- Get NTFS-3G and install on OSX: http://www.tuxera.com/community/ntfs-3g-download/
There is no app to run since OSX operating system is updated directly. You will also be able to format external drives to NTFS after the install is complete in OSX Disk Utility. You can uninstall MacFUSE or NTFS-3G from System Preferences.
