System Requirements

These scripts are designed to be as extension attributes within Casper's JAMF Software Server (JSS). Most of them are written in Python.

• Python 2.7 (included in MacOS)

Install

These scripts are designed to be copy-and-pasted into a script field in a JSS extension attribute field.

Uninstall

Delete the extension attribute.

Purpose

These scripts are meant to expand the capabilities of JAMF Pro utilizing the Extension Attribute mechanism. JAMF's EA documentation can be found here. Using the information returned by an EA, you can build smart groups. Being a member of a specific smart group can cause additional actions to take place. For example, if the Bluetooth battery level is low, an email could be sent to the user remining them to change the batteries.

Please feel free to use the code provided to build your own scripts.
