If you have any external hard drives with ntfs file format (MS Window XP, etc) and you need read - write permissions when connecting them to your mac, then this is for you!It works with any ntfs partition connected to your system.
How it works? it just overrides the ... poor mac os's pre-installed driver for mounting ntfs file systems.
NTFS-3G can be disabled / uninstalled anytime.
This utility includes macfuse packages as well. Macfuse is a collection of headers. Note that it does not load any drivers or affect your system in anyway!
