The attached tool to assist with cleanup and repair following the JMP Student Edition 19 installation and authorization issue on macOS.
To recap: The issue arises because JMP Student Edition 19 creates a folder at ~/Application Support/JMP that is owned by root, preventing the user from modifying or writing to it.
The attached tool prompts for an administrator username and password, then moves the problematic folder to the Trash.
Below are the dialogs displayed when running the application.



Do not attempt to fix this problem by creating folders inside the offending folder. This would leave a folder owned by root in the home directory and could cause problems in the future.
