You need to install fuse4x and ntfs-3g for NTFS write support in OS X Mavericks:
brew update
brew install fuse4x
brew install ntfs-3g
sudo mv /sbin/mount_ntfs /sbin/mount_ntfs.orig
sudo ln -s /usr/local/Cellar/ntfs-3g/2013.1.13/sbin/mount_ntfs /sbin/mount_ntfs
brew info fuse4x-kext
After "brew info fuse4x-kext" command, you'll see two commands:
sudo /bin/cp -rfX /usr/local/Cellar/fuse4x-kext/0.9.2/Library/Extensions/fuse4x.kext /Library/Extensions
sudo chmod +s /Library/Extensions/fuse4x.kext/Support/load_fuse4x
Execute these commands and reboot your system.
Your system will able to write in NTFS file systems after reboot.
Please note that ntfs-3g now requires osxfuse which conflicts with fuse4x ..
