Mounty for NTFS

A tiny tool to re-mount write-protected NTFS volumes under Mac OS X 10.9+ in read-write mode.

Easy: A menu icon

Start the program and see it in action:

You will be notified if there is any volume connected to the computer which is NTFS formatted and ready to re-mount in read-write mode.

Light: A simple design

Mounty for NTFS comes without any decorations.

No additional driver will be installed. It simply makes use of the build-in mechanisms already provided by Mac OSX Mavericks - no strings attached.

Get: Click to install

Mounty for NTFS is available for free. You can get it here right now.

If you prefer Homebrew , you'll probably know what to do: brew cask install mounty

To support further development of Mounty, we encourage you to make a donation via Paypal:


From the icon in menu bar you can always bring a finder window to front to manage the contents of the mounted drive.

The colour of menu icon reports the current state:

  • inactive - nothing to mount
  • active - Volume available to re-mount
  • idle - Volume writable mounted
  • error - mount failed

A bit of background

Occasionally I need to share files with my colleagues via USB sticks. Since we are working on different platforms the sticks might be NTFS-formatted. No problem so far, there are several resources out to the web describing to accomplish this task, e.g.

I personally have chosen the more pragmatic way, just open a terminal and issue some mount commands like:

        macbook:~ uwe$ sudo umount /Volumes/UNTITLED
        macbook:~ uwe$ sudo mount -t ntfs -o rw,auto,nobrowse /dev/disk3s1 ~/ntfs-volume

However, tired of typing this over and over, I have written Mounty to accomplish exactly this - but in a much more convenient fashion. So, under the hood, it happens an unmount and a remount short after, followed by opening a Finder window pointing to the hidden mount point.

Please let me know if this tool is also useful to you; and do not hesitate to ask a question that might appear using Mounty.


Some questions that might come up

My USB stick will not re-mount. An alert is popping up telling me to re-attach the stick, but this doesn't help.

This can happen when the USB stick is not cleanly unmounted from the Windows PC. If you simply unplug the USB stick from PC without using the little tray icon to detach the hardware correctly, the volume will be marked as "not cleanly unmounted". There might be some dirty sectors left and Mac OS X will not be able to re-mount in read-write mode for that reason.

Suddenly all my files disappeared - please help!

Mounty will not delete anything by itself. Try to restore your files on a Windows PC using usual recovery s/w, i.e. chkdsk command line utility or professional tools like GetDataBack for Windows.

Sometimes the files are grayed out and cannot be modified anymore.

This is because the file has extended attributes, refer to the Manpage of xattr for further explanation. If you open the file path in terminal application, you can list the attributes with ls -l@ <filename>, and remove those attributes with xattr -d com-apple.<attribute> <filename>, i.e.: xattr -d com.apple.FinderInfo testfile.txt
