While Mac OS X Leopard has no native support for NTFS (write), you can use third party software like Paragon NTFS read / write to NTFS drives. But Snow Leopard has a big surprise. You can enable write access to NTFS without any additional software.

Here `s how you can do

  1. In Terminal, type diskutil info /Volumes/volume_name, where volume_name is the name of the NTFS volume. From the output, copy the Volume UUID value to the clipboard.
  2. Back up /etc/fstab if you have it; it shouldn’t be there in a default install.
  3. Type sudo nano /etc/fstab
  4. In the editor, type UUID=, then paste the UUID number you copied from the clipboard. Type a Space, then type none ntfs rw. The final line should look like this: UUID=123-456-789 none ntfs rw, where 123-456-789 is the UUID you copied in the first step.
  5. Repeat the above steps for any other NTFS drives/partitions you have.
  6. Save the file and quit nano (Control-X, Y, Enter), then restart your system.
