Enable ntfs write support in Mavericks
You can enable write support for ntfs in Mavericks.
I have linked to instructions on how to do this, but the gist of it is to edit the /etc/fstab file and add a line for each ntfs drive you want to write to:
LABEL=device-name none ntfs rw,auto,nobrowse
changing "device-name" to the name of your ntfs drive.
This is a per device hack.
Third party software
Alternatively, there is a lot of third party software to give you full ntfs support, such as Paragon NTFS, or the open source NTFS-3G for FUSE which is utilized in the closed source Tuxera NTFS, or an old standard from Thursby Software, DAVE
NTFS-3G and OSXFUSE are available for a free, package managed source or binary installation using the missing package manager for OS X, MacPorts, which is mature, stable and fully supported, unlike alternative package management solutions for OS X. It is based off of FreeBSD's ports system, which is based off the finest package management system known to exist, of course I mean, NetBSD's pkgsrc. It won't let you down!
Installing MacPorts, NTFS-3G and OSXFUSE is simple enough once xcode (for Mavericks 10.9 xcode_5.1.1.dmg) is installed. Install xcode, and then enter these commands in Terminal.app :
curl -Ok https://distfiles.macports.org/MacPorts/MacPorts-2.2.1.tar.bz2
tar xf MacPorts-2.2.1.tar.bz2
sudo make install #not war!
rm -rf Macports-*
sudo /opt/local/bin/port -v selfupdate
sudo port -vsc install ntfs-3g # osxfuse is a dependency, macports will install it for you when you instsall ntfs-3g
diskutil quiet repairPermissions /
MacPorts is worth getting to know as it is a mature package manager for OS X that maintains thousands of open source software commands, utilities, and applications. It will not interfere with any other package system you happen to use, and it is very easy to completely remove, if necessary.
If for whatever reason you need to remove MacPorts...
to completely uninstall MacPorts
sudo port -dfp uninstall --follow-dependencies installed
sudo port -dfp uninstall all
sudo rm -rf /opt/local
sudo rm -rf /Library/Tcl/macports*
Really, its good stuff.
