Mac or PC:
Mac OS X and Windows operating system use different file systems such as HFS+ AND NTFS, FAT, etc, so most of the hard drive manufacturers offer specific platform models. If you used Mac OS X then it can read files on an NTFS only but you can’t write anything on them. If you intend to use the same drive on both the platforms then you have to download the software on your Mac OS then it will enable to do both the tasks. If you prefer commercial software for Mac then you can take the help of Paragon NTFS ($20) or Tuxera NTFS ($32).
