automount all ntfs volume writable in macOS Big Sur+

readme.md

Prepare

Disable SIP first, download and Install macFUSE from https://osxfuse.github.io/, then do the following

brew tap gromgit/homebrew-fuse
brew install ntfs-3g-mac

Install

Download ntfs and mount_ntfs_3g.plist and then

chmod +x ntfs
sudo chown root:wheel ntfs
cp ntfs /usr/local/bin/ntfs

Set up to run automatically

chmod 600 mount_ntfs_3g.plist
chown root:wheel mount_ntfs_3g.plist
sudo cp mount_ntfs_3g.plist /Library/LaunchDaemons/
sudo launchctl load /Library/LaunchDaemons/mount_ntfs_3g.plist

Enjoy and you can also enable SIP now.

Q&A

Why is the script delayed by 3s?

Avoid the system's automount from overwriting our writable mount.
