Write ntfs file system in el capitan I have a hard disk which is in NTFS.
I want to make it writable without formatting.

I have gone through some solution for it but its working in previous version not in el captian.

I tried this link
but when doing this step 

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


its says its not permitted.
It is writeable when you use a ntfs driver: it is not the disk but the OSX that you should "help".
 There are several: the most experienced (in my opinion) are Tuxeira NTFS (opensource) and Paragon NTFS. Lately Tuxeira is the fastest update when the OSX is updated/upgraded.
