For best results use on macOS devices enrolled via Automated Device Enrollment AKA DEP with MDM profile removal disabled. 8 | 9 | ## //How To Install// 10 | 11 | Add the Install and Check script to your Jamf Pro Server and assign to polices as noted below 12 | 13 | ## //Install Script// 14 |
#Context: This should be a script in Jamf Pro assigned to/run via a Policy 15 |
#Purpose: Create and load the files needed to monitor and self heal Jamf Pro enrolment if framework is removed 16 |
#Policy Scope: All Computers & All Users (or just user/device groups where users have admin rights) 17 |
#Policy Site: None/All or inline with above 18 |
#Policy Frequency: Once Per Computer 19 |
#Policy Trigger: Check-In or Enrolment or Start-Up 20 | 21 | ### Define Variables 22 | 23 | 1. Jamf Pro URL 24 | 2. Invitation ID 25 | 26 |
#Note: make sure to edit between the "" quotes. Leave all other formatting intact 27 |
#Include port number in URL and do not use ending slash as per examples in the script 28 | 29 | ### How to get Invitation ID? OLD WAY 30 | 31 |
#On any macOS device, use the Jamf Recon.app to generate a quick add package with the 32 |
#correct settings for enrolment including management account, SSH settings, etc 33 |
#Then, use composer or similar tool to extract the post-install script 34 |
#Near the end of the script will be a multi-use enrolment ID like the one seen below 35 |
#Replace the one below with your invitation ID from the QuickAdd package 36 |
#IMPORTANT: do not generate your QuickAdd package from the User Initiated Enrolment Page 37 |
#This will give you a one time enrolment ID which will not work for this use case 38 |
#Only use an ID found in a recon generated QuickAdd package 39 | 40 | ### How to get Invitation ID? NEW WAY 41 | 42 |
As Recon is being deprecated in a future release of Jamf Pro I now suggest to use the API to get the ID. 43 |
Head to https://yourJAMFPROserver/classicapi/doc/#/computerinvitations/findComputerInvitations and authenticate to the swagger UI. 44 |
Use the "Try It Out" feature to get a list of invitiations. Look for "invitation_type":"DEFAULT" and copy the long numeric "invitation" string before it. 45 | 46 | 47 | ## //Check Script// 48 |
#Context: This should be a script in Jamf Pro assigned to/run via a Policy 49 |
#Purpose: Verify a computer is communicating with the JSS correctly & quickly 50 |
#Policy Scope: All Computers & All Users 51 |
#Policy Site: None/All 52 |
#Policy Frequency: Ongoing 53 |
#Policy Custom Trigger: JamfWATCHCheck 54 |
#Example Command to Run on Client Machine: 55 |
