Windows Formatted Drive on Mac

Most of the time a Macintosh computer will be able to read from a drive formatted for Windows (NTFS), but sometimes it will not. If you have a need to read a drive that is NTFS formatted on a Mac, one program that you can use is called Tuxera - NTFS for Mac.

If you have a common need to be able to read and write to an NTFS drive or if you want to fully share a drive between Mac and Windows this is a worthwhile purchase. If you just need to get the data off of a Windows formatted drive the trial period will give you 14 days.
