How to Read/Write External Hard Drive / USB with NTFS on Mac OS X? (with Troubleshooting)

NTFS (New Technology File System) is a file system developed by Microsoft. FAT32, which is also commonly used, is another example of file system. They define and control how the data, or files, are stored and retrieved from a storage drive. However, Mac OS X supports NTFS read only, but not write, by default. There are software that can enable NTFS write. Yet, it is easy and free to enable the access by a few steps. Here is a complete guide.

1. Open “Terminal“.

There are 3 ways to open terminal.

  1. Open it via “Spotlight” on the top-right comer or “Cmd + Space” (default short-cut key), and type “Terminal“.
  2. Another way is to open “Finder“, “Go to Folder…”/Applications/Utilitiesand you should find “Terminal” there.
  3. Press “F4” >> open folder “Other” >> click the icon of Terminal

A new Terminal window should be prompted out. If you are a geek, I believe you need it quite often, keep it in Dock now~
