How to enable NTFS 3G?
Alternative approach

While you can use NTFS-3G for accessing NTFS drives, it should be noted that recent versions of macOS support writing to NTFS drives natively. This option however is hidden from the GUI and you'd normally need the terminal to do it:

sudo mount -t ntfs -o rw,auto,nobrowse /dev/disk3s1 ~/ntfs-volume


Uwe Hollatz created Mounty, which is a nifty tool to automate this process. It sits in your taskbar waiting for NTFS drives to be detected. 



If you use Homebrew, install it with the following command:

brew cask install mounty


Otherwise, download the DMG from its website.
