NTFS Read/Write support on Mac OSX Lion

Posted on 2012-01-19 by Frankie

One of the first problems I encountered on my Mac was how to manage some external drives using NTFS. After reading a number of blogs, postings and articles I found the one by Sergey Vasilyev to be the best. The following is a quick guide to getting NTFS read/write support on OSX Lion.

Tuxera MacFuse 2.2: Download Tuxera MacFuse 2.2 from here and install.
NTFS-3G: Download NTFS-3G from here and install.
fuse_wait: Update the fuse_wait script by downloading and installing the setup from here.

Next time you connect a storage device with NTFS you should be able to read/write from/to it.
Do note that there are a number of paid alternatives and a more detailed explanation can be found in the original blog of Sergey Vasilyev at http://blog.nolar.info/ntfs-3g-in-mac-os-x-lion-10-7-with-read-write-support/
