This is experimental, and known to be unstable, use at your own risk.
You need to modify /etc/fstab file to mount NTFS partitions for read and write.
- First, uninstall NTFS-3G/Paragon if installed.
- Open Terminal
run diskutil info /Volumes/volume_name and copy the Volume UUID.
Backup /etc/fstab if you have it (shouldn't be there in a default install).
- Run sudo vim /etc/fstab and write:
UUID=paste_the_uuid_here none ntfs rw
LABEL=volume_name none ntfs rw
(if you don't have UUID for the disk).
- Repeat for other NTFS partitions.
- Restart your system.
