To fix this, you will need to install the Paragon Driver software which allows your Mac to write to the drive (modify or put new files on the drive) without limiting its Windows functionality. This means you can look at and open files on the drive, but not modify or put new files on it. This is because the drive is formatted for Windows and is “read-only” on Mac.
