== ntfs-3g on MacOS

  csrutil disable


  brew install ntfs-3g


  volname=Toshiba_1tb
  diskutil list | grep $volname  
  1:               Windows_NTFS Toshiba_1tb             1.0 TB     disk2s1

  disk=$(diskutil list | grep $volname | awk '{print $NF}')

  sudo mkdir /Volumes/$volname
  


From https://github.com/osxfuse/osxfuse/wiki/NTFS-3G :

If volume is APFS, then it will need to be unlocked to install mount_ntfs. Let's assume that Macintosh HD is identified as disk1s1.

  diskutil list
  diskutil apfs unlockVolume disk1s1

To replace Apple's NTFS mount tool with the one provided by NTFS-3G execute the following commands in Terminal. This will back up the original mount tool to /Volumes/Macintosh HD/sbin/mount_ntfs.orig.

  sudo mv "/Volumes/Macintosh HD/sbin/mount_ntfs" "/Volumes/Macintosh HD/sbin/mount_ntfs.orig"
  sudo ln -s /usr/local/sbin/mount_ntfs "/Volumes/Macintosh HD/sbin/mount_ntfs"

or why not simply : (to try)

  sudo mv "/sbin/mount_ntfs" "/sbin/mount_ntfs.orig"
  sudo ln -s /usr/local/sbin/mount_ntfs "/sbin/mount_ntfs"


Maybe simplify with unmount/mount? See https://apple.stackexchange.com/a/338692/14586
