   diskutil list

   Locate the device (e.g., /dev/disk2s1) and mount point (e.g., /Volumes/MyNTFSVolume) of your NTFS volume in the output.
3. Unmount the NTFS volume. Replace <YOUR_NTFS_DEVICE> with the actual device name, and enter the following command in Terminal:

   sudo diskutil unmount /dev/<YOUR_NTFS_DEVICE>

   For example, if your NTFS device name is /dev/disk2s1, enter sudo diskutil unmount /dev/disk2s1.
4. Remount the NTFS volume using ntfs-3g. Replace <YOUR_NTFS_DEVICE> with the actual device name and <YOUR_NTFS_MOUNT_POINT> with the actual mount point, and enter the following command in Terminal:

   sudo ntfs-3g /dev/<YOUR_NTFS_DEVICE> <YOUR_NTFS_MOUNT_POINT>

   For example, if your NTFS device name is /dev/disk2s1 and the mount point is /Volumes/MyNTFSVolume, enter sudo ntfs-3g /dev/disk2s1 /Volumes/MyNTFSVolume.
