How to synchronize two folder on MacOS

After failure with ln as it is not compatible with git, I finally found a effective way to make a synchronization automatically on MacOS.

How to setup

  1. open your automator

  2. Choose Folder Action

  3. The upper folder path is the source folder path, and the lower one is the target folder path.
