wiki:howto/Ntfs3gFinder

These instructions have been liberally copied from this excellent blog post.

Step 1. Install the ntfs-3g port.

sudo port install ntfs-3g

Step 2. Find out your userid and groupid.

User ID:

id -u

Group ID:

id -g

Step 3. Use a modified mount_ntfs executable and save the OS X original to /sbin/mount_ntfs.orig

(Note to do this under El Capitan, you must first disable SIP. See this how-to)

sudo mv /sbin/mount_ntfs /sbin/mount_ntfs.orig
sudo touch /sbin/mount_ntfs
sudo chmod 0755 /sbin/mount_ntfs
sudo chown 0:0 /sbin/mount_ntfs
sudo nano /sbin/mount_ntfs

Then paste in the following code and save it by typing Control-X and pressing "Y". NOTE:

  • You can optionally substitute in your User ID and Group ID (from Step 2 above) in place of 501 and 20 in lines 4 and 5 below.
  • This script also assumes the standard MacPorts install location of /opt/local/ so you will need to modify it if yours is different.

        if [ "$USERNAME" = "" ]; then
                until [ `stat -f "%u" /dev/console` -ne 0 ] || [ $TIMEOUT -eq 0 ]; do
                        sleep 1
                        let TIMEOUT--
                done
