Can macOS High Sierra write to NTFS external drives?

Solution 1:

You actually can, and I just did it.

In short:

• note the label of your NTFS volume.
• edit /etc/fstab even if it doesn't exist, e.g. with sudo vi /etc/fstab
• Add this line for every NTFS volume: LABEL="VOLUME_NAME_WITHOUT_QUOTES" none ntfs rw,auto,nobrowse
• Re-plug your drive.

You will not see the drive in Finder's "Devices", because this option requires nobrowse to work, but it is mounted in /Volumes/<ntfs_label>

Solution 2:

By default, no, High Sierra only gives read support for NTFS. You can enable write support with popular free tools like FUSE + NTFS-3G.

If you have Paragon or Tuxera, then you paid for a support and they will certainly help you to install the latest compatible version of their respective softwares.
