1. Modify your swiftDialog installation policy, by selecting the Scripts payload and adding the swiftDialog Pre-install script, specifying the following Parameter Value
   • Script Log Location: /var/log/com.company.log
   • Installation Action: none
2. Optionally add the Files and Processes payload and specify the following one-liner for the Execute Command

/usr/bin/chflags hidden "/Library/Application Support/Dialog/"

Breaking change for Jamf Pro Admins prior to version 0.0.4

Version 0.0.4 modifies the Script Parameter Label for scriptLog — changing it to a hard-coded variable in the script (as it should have been all along) — Sorry for any Dan-induced headaches.

Additionally, the Script Parameter for subtitle has been removed.

(We used Object Info to determine which policies needed to be updated.)

1. Add the swiftDialog Notifications script to your Jamf Pro server
2. Specify the following for Options > Parameter Labels
   • Parameter 4: Title
   • Parameter 5: Message
   • Parameter 6: Button 1 Text
   • Parameter 7: Button 1 Action
   • Parameter 8: Button 2 Text
   • Parameter 9: Button 2 Action

For this test, we prompted the user to login to the Workforce App Store (a.k.a. Self Service) and manually run the update computer inventory policy.

1. In Jamf Pro, navigate to the Update Computer Inventory policy which you’ve previously made available in Self Service and note its ID number
2. Create a new Jamf Pro policy, using the following as a guide for Options > General:
   • Set Display Name to swfitDialog Notification Test (0.0.4)
   • Set Execution Frequency to Ongoing
3. Select the Scripts payload and add the swiftDialog Notifications script, specifying the following Parameter Values (and replacing NNN with the ID from Step No. 1.
   • Title: Update Inventory
   • Message: Please login to Self Service and update your computer inventory
   • Button 1 Text: Update
   • Button 1 Action: jamfselfservice://content?entity=policy&id=NNN&action=view
   • Button 2 Text: Close

3. Adjust Scope to your liking; we limited testing policies to our opt-in Beta Testers
4. Use the following for Self Service
   • Self Service Display Name: swfitDialog Notification Test (0.0.4)
   • Button Name Before Initiation: Test
   • Button Name After Initiation: Test
   • Description: Tests macOS Notifications with swiftDialog
5. Use the following for User Interaction
   • Start Message: Jamf Pro built-in Notification
6. Click Save
7. Launch Self Service and test the swfitDialog Notification Test (0.0.4) policy

Test modifying Button 1 Action to execute the Self Service policy by replacing view with execute.

Button 1 Action: jamfselfservice://content?entity=policy&id=NNN&action=execute

Rule of Two

To display any options in a Notification, you must follow the Rule of Two and ensure you populate both Button 1 Text and (at least) Button 2 Text as illustrated above and below:

dialog \
    --notification \
    --title "Single Option?" \
    --subtitle "Single choice does NOT display" \
    --message "(The entire Notification is a button.)" \
    --button1text "This will NOT display in macOS" \
    --button1action "https://developer.apple.com"

dialog \
    --notification \
    --title "swiftDialog Wiki" \
    --message "Have you checked Bart's Wiki?" \
    --button1text "No" \
    --button1action "https://github.com/swiftDialog/swiftDialog/wiki" \
    --button2text "Yes" \
    --button2action "https://snelson.us/?s=swiftdialog"
