If an NTFS drive is connected to Mac OS locally, such as via IDE, SATA, or USB, you need Paragon NTFS for Mac OS X to be able to write data to the NTFS partition. Mac OS X itself can only read local NTFS drives.
However, for accessing a remote folder shared from another PC, you don’t need any special drivers. That folder can be located on any file system, and transparent access to its data is provided by operating system on that remote machine through network protocols. The data is read and written by the remote operating system, and transmitted over the network via TCP/IP. So your Mac OS X only needs to support TCP/IP network protocols, which all modern operating systems do.
You only need to check if the network is configured properly and if the shared folder has correct access permissions.
