If you have used the Dreamweaver CC 2017 Beta, and now have Dreamweaver CC 2017 installed, you may experience some errors while syncing settings with other Dreamweaver installations available across machines.
If sync settings fails inspite of multiple retries, download the following script and run it with administrative privileges. This script provides a fix for the sync settings issue.
Extract the file and run it. After you see the following success message (this may differ slightly on Mac), try syncing settings once again.
Extract the file, and then execute the following command on the terminal:
sudo sh <downloaded script path>
