Mount NTFS drives as writable on macOS

ntfs.sh

    diskutil info $dev|grep NTFS>/dev/null

Failure to mount an NTFS disk is usually caused by the disk being in a "hibernation" or "dirty" state due to not being safely removed on Windows.

Typical fix:
Connect it back to a Windows PC and safely eject it, or repair it using chkdsk:

chkdsk /f X:

(Replace X with the actual drive letter of your hard disk.)

Even this may not always work. Just make do with it for now.

You can also install Mounty.
Run these three commands:

brew install --cask macfuse
brew install gromgit/fuse/ntfs-3g-mac
brew install --cask mounty

Mounty version 2 now acts as a graphical user interface for the third-party driver NTFS-3G. This brings NTFS write support back to macOS, but the installation is now a bit more complex. You need two additional pieces of software to use with Mounty 2: macFUSE and NTFS-3G for Mac.
