No, OS X doesn't use NTFS.
Programs aren't written for file systems--thus why programs like Firefox can run on the NTFS-using Windows XP while also running on the FAT32-using Windows 98--they're written for system architectures. Windows is an inherently more corruptible platform, because Microsoft wrote the underlying architecture with the operating assumption that every other computer on the network could be trusted.
This is what I actually wrote:
"Isn't NTFS basically the same type of file system as MAC?"
I never said that Mac uses NTFS.
The issue at hand was security. I should have been more specific. I was referring to 'access rights' which can be assigned to each file.
I believe both OS have similar ability to assign access rights.
