Paragon NTFS for Mac 15 ($20) is a file system driver that allows Mac OS X Yosemite and later (incuding macOS Sierra) to read and write to hard drives, solid-state storage devices, and USB thumb drives formatted for Windows systems.
Macs have always been able to read and write to another Windows format, FAT (File Allocation Table), but this older format isn’t well suited to today’s larger capacity drives, maxing out at 2TB with FAT32.
Microsoft has since moved on to exFAT, which resolves the 2TB limitation while natively supported for read and write on Mac. But NTFS remains the de facto standard for most PC users. With this software installed, working with such volumes is seamless.
