Based on: http://apple.stackexchange.com/questions/152661/write-to-ntfs-formated-drives-on-yosemite
I use El capitan 10.11.1.
I followed the instructions, before creating a symlink for mount_ntfs, I disabled SIP, and after creating symlink I re-enabled SIP. But no success. I can't write to a NTFS formatted external disk.
