Building this package

You will need to use munki-pkg to build this package.

Credits

This tool would not be possible without nibbler, written by Michael Lynn.

Notes

Because of the way git works, nudge will not contain the Logs folder required for the postinstall to complete.

In order to create a properly working package, you will need to run the following command: munkipkg --sync /path/to/cloned_repo/nudge.

OS Support

The following operating system and versions have been tested.

• 10.10.0, 10.10.5
• 10.11.0, 10.11.6
• 10.12.0, 10.12.6
• 10.13.0 10.13.3, 10.13.6
• 10.14.0

Configuration File

Essentially every component of the UI is customizable, all through a JSON configuration file. An example file is available within the code repository.

Defined config file

To define a configuration file, use the jsonurl script parameter.

--jsonurl=https://fake.domain.com/path/to/config.json

--jsonurl=file:///path/to/local/config.json

Default config file

If you prefer to deploy the configuration file to each client, it needs to be placed in the Resources directory and named nudge.json. If this file exists, jsonurl does not need to be set.
