Update Homebrew:
> brew update

Install osxfuse:
> brew cask install osxfuse

Install ntfs-3g:
> brew install ntfs-3g

Link mount_ntfs:
> sudo mv /sbin/mount_ntfs /sbin/mount_ntfs.original
> sudo ln -s /usr/local/sbin/mount_ntfs /sbin/mount_ntfs

The output of the following should be as below:
> ls -l /sbin/mount_ntfs*
/sbin/mount_ntfs -> /usr/local/sbin/mount_ntfs
/sbin/mount_ntfs.original -> /System/Library/Filesystems/ntfs.fs/Contents/Resources/mount_ntfs

Reboot and voila
