As you may have already known, Apple has launched macOS Sierra 10.12.4 and introduced a new file system – APFS.
Apple File System is available in macOS Sierra, but with numerous limitations and is considered experimental.
Among the limitations:
Will Paragon HFS+ for Windows be able to handle APFS after the file system’s changed?
Nope. HFS+ for Windows is not able to operate with APFS-formatted disks and drives.
In order to be able to read APFS volumes, you need Paragon APFS for Windows.
