Ask a question
This tutorial explains how to write on a volume formatted in NTFS without using any third party software. In our example we have used a Mac running OS X version 10.8 (Mountain Lion). The procedure is different for Mac OS 10.5, 10.6 and any other version above 10.9. The term "NTFS volume" may refer to a partition, an entire hard drive or a USB drive.

Write on NTFS volume in Mountain Lion

Make sure you don't have any third party software (Paragon NTFS for Mac, Tuxera, NTFS-3G etc...) allowing you to write on NTFS volumes installed on your Mac, including demo versions. Go to Applications > Utilities and open a terminal. Enter the sudo nano /etc/fstab command and confirm:

Enter your password when requested. A new fstab file will be created in /private/etc.

In the terminal nano editor window, type:

LABEL=name_of_volume none ntfs rw,auto,nobrowse

Replace name_of_volume by the exact name of your NTFS volume.

Press CTRL + X to exit nano editor and tap on Y to confirm the backup:

Then tap the Enter key to validate:

Following this operation the selected volume will disappear from your desktop. You need to mount it again. Open a terminal and type open /Volumes/name_of_volume to access the selected volume directly or open /volumes:

The second command opens a window listing all the available volumes, you can then select the NTFS volume. To avoid having to repeat this operation in the future, simply drag the windows titled as Volumes to the Favorites section of the Finder's Sidebar. Thus after restarting your Mac your NTFS volume can be easily accessed using the Favorites menu.
