Hello everyone!

We like to alert our users of new software deployments and patches via popup notification, through SCCM in Windows this is an easy task. Currently for our Mac environment when I go to deploy a new update or software push I have to :

-Create a pdf with what software is being deployed and the time of deployment
-Push the pdf to the shared folder -Setup a policy to run through remote to open the PDF at a certain time in the AM

It seems like an awful lot of work for something fairly simple. Anyone have any better practices for deploying a popup notification to end users with new software or patches, unfortunately we can't use notification center because it's not obvious enough.

Thanks in advance.

Too much work you're doing there. Use some of the built in functionality in the JSS version 9.x, like the User Interaction tab in a policy. Or a script calling jamfHelper, AppleScript, cocoaDialog, etc. There are loads of ways of getting a message up in front of a user that don't involved creating and deploying a full document.

stevewood · ‎02-04-2015

@jeffrey_ngo jamfHelper would be the easiest way that I can think of to do it. If all you are doing is deploying some text about what software updates are being pushed, it would be relatively easy to setup a policy in the JSS to do this. The syntax of jamfHelper is:

banner=`/Library/Application Support/JAMF/bin/jamfHelper.app/Contents/MacOS/jamfHelper -windowType hud -title "<windowtitle>" -heading "<paragraphheading>" -description "<text of what you are doing>" -icon <iconfile> -button1 "Proceed" -button2 "Not Now" -defaultButton 1 -cancelButton 2 -timeout 60 -countdown`

That will place a HUD window in the middle of the screen, place two buttons and a timeout of 60 with a countdown.

You can simply issue the jamfHelper command with -help to get more info:

/Library/Application Support/JAMF/bin/jamfHelper.app/Contents/MacOS/jamfHelper -help

Hope that helps you out.

What about a script that creates a pop-up notification?

#!/bin/bash

# This script displays a message that lets the user know that 
# a browser installation policy has finished. It is set 
# to the lowest priority to ensure that it runs last after all 
# other scripts and policy actions.

# Determine OS version
osvers=$(sw_vers -productVersion | awk -F. '{print $2}')

dialog="hello world."
description=`echo "$dialog"`
button1="OK"
jamfHelper="/Library/Application Support/JAMF/bin/jamfHelper.app/Contents/MacOS/jamfHelper"
icon="/path/to/icon"

if [[ ${osvers} -lt 7 ]]; then

  "$jamfHelper" -windowType utility -description "$description" -button1 "$button1" -icon "$icon"

fi

if [[ ${osvers} -ge 7 ]]; then

  jamf displayMessage -message "$dialog"

fi

exit 0

I think I got this from @rtrouton but I can't find the github path for whatever reason.

jeffrey_ngo · ‎02-04-2015

Thanks so much everyone!

This will be immensely helpful in saving time!

rtrouton · ‎02-04-2015

I've got a number of message scripts like the one @emilykausalik referenced. They're available from here:

John_Wetter · ‎02-04-2015

If you're using Self Service, you could also turn on notifications in the app via the JSS.

tkimpton · ‎04-07-2016

@stevewood that looks great but do you go about scripting if someone clicks proceed then go and do XYZ?

thoule · ‎04-07-2016

As long as we're sharing.. I have a script called "Notify User". Then in a policy I can call that script with parameters.

#!/bin/sh                                            
#thoule
#displays jamf help message.

JH="/Library/Application Support/JAMF/bin/jamfHelper.app/Contents/MacOS/jamfHelper"
JHaddon=" -windowType utility -title IS_Updates -icon /usr/local/CORP/Logos/Logo_Black.png -windowPosition $6"
"$JH" $JHaddon -description "$4" -button1 $5  -timeout $7

Then under Script Options, I name Parameter 4 "Notification Text (Required)"
Parameter 5 "ButtonText (Optional)"
Parameter 6 "Location: ctr, ul, ll, ur, lr (optional)"
Parameter 7 "Timeout (Optional)"

Location is upper left, lower left, etc. Don't leave both Timeout and ButtonText empty!

stevewood · ‎04-07-2016

@tkimpton The short answer is yes. I don't typically use notifications to get permission to continue, with the exception of using @mm2270's Select Software Update script for updates. WIth that script it utilizes cocoaDialog to throw up a notification that the user can select updates and install, and then stays in the foreground as it installs (giving a progress bar for the user).

I typically use jamfHelper for "in your face" HUD style notifications when doing background installs at login or logout. For example, I just had to push Adobe Acrobat updates out at login, and I throw up a jamfHelper HUD to let folks know that is what is happening and to not open Acrobat until that dialog disappears. There is no button for them to clear the dialog (although if they were smart they could click on it and CMD-Q to quit it).

And like @thoule, my jamfHelper call is done via a script that allows me to select the image that is displayed, heading, text displayed, and icon.

Hope that answers your question.

jameson · ‎12-12-2018

@mm2270 Script is really great. I cannot imagine how long this script has taken to create

It is nearly 100% of what we need, but hope some scripts experts can help with a single change

Default it shows which available software there is to install. Can it be changed so there is no choice (checkmark greyed out or similar) - but popup just appear and name of software listed that needs to be updated and users then can use the "install now" button.
software Update information should appear on the screen, but users should not have an option check which software they want to install - some are even afraid of installing something.

mm2270 · ‎12-12-2018

@jameson I actually have a version of the script where you can set a variable up near top to do exactly what you're asking. I should just say though that I really haven't used this script in a long time now, and I have heard that it may not work anymore on more recent OSes, like High Sierra and Mojave, but again, I haven't had the chance to test it to see. If you find it's working for you, then that's awesome and I'm glad to hear it!

I'll dig thru my script repo to locate the version that includes that option and post it here when I find it. It's just a flag you can set to enable that function. I believe it still allows for canceling the dialog however, so I don't know if you just want an "Install Now" button and nothing else. If so, I will tell you which line in the script to modify to make that change.

Captainamerica · ‎12-12-2018

Thank you very much - would be great and would love to have Those script skills but still quite new to Jamf.

The Best would be if users just Can click install now or a countdown shows when it is going to auto start the Update

Captainamerica · ‎12-12-2018

Sorry wrote it wrong. Actually updates should show up and countdown start fx x minutes before it installed - or user Can initiate install on their own.
Before rebooting (if needed) popup should appear to inform users and again countdown x minutes before auto restart

mm2270 · ‎12-12-2018

OK, so here is that version of the script I mentioned. Use at your own risk, since I haven't tested it against current OS versions as I said earlier. (As you can see, it was July 2016 when I last touched it)

#!/bin/bash

##  Script Name:        Selectable_SoftwareUpdate.sh    (v005)
##  Script Author:      Mike Morales, @mm2270 on JAMFNation
##  Last Update:        2016-07-19

##  Path to cocoaDialog (customize to your own location)
cdPath="/Library/Application Support/JAMF/bin/cocoaDialog.app/Contents/MacOS/cocoaDialog"

##  Quick sanity check to make sure cocoaDialog is installed in the path specified
if [ ! -e "$cdPath" ]; then
    echo "cocoaDialog was not found in the path specified. It may not be installed, or the path is wrong. Exiting..."
    exit 1
fi

##  Set the installAllAtLogin flag here to 'yes' or leave it blank (equivalent to 'no')
##  Function: When the script is run on a Mac that is at the login window, if the flag is set to 'yes',
##  it will lock the login window to prevent unintended logins and proceed to install all available updates.
##  Once completed, the login window will either be unlocked in the case of no restarts needed,
##  or a restart will be done immediately to complete the installations.

installAllAtLogin="yes"

##  Set the forceEnableUpdates flag below to 'yes' (or any value) to enable it. This option will change the
##  checkbox display to show updates as enabled and non-selectable to the user, meaning they will be forced to
##  an "on" state for all. Leaving this value blank will retain the original functionality, allowing the end
##  user to select the updates they would like to install.

forceEnableUpdates="yes"

##  Get minor version of OS X
osVers=$( sw_vers -productVersion | cut -d. -f2 )

##  Set appropriate Software Update icon depending on OS version
if [[ "$osVers" -lt 8 ]]; then
    swuIcon="/System/Library/CoreServices/Software Update.app/Contents/Resources/Software Update.icns"
else
    swuIcon="/System/Library/CoreServices/Software Update.app/Contents/Resources/SoftwareUpdate.icns"
fi

##  Set appropriate Restart icon depending on OS version
if [[ "$osVers" == "9" ]]; then
    restartIcon="/System/Library/CoreServices/loginwindow.app/Contents/Resources/Restart.tiff"
else
    restartIcon="/System/Library/CoreServices/loginwindow.app/Contents/Resources/Restart.png"
fi

##  Start - Check Casper Suite script parameters and assign any that were passed to the script

##  PARAMETER 4: Set the Organization/Department/Division name. Used in dialog titles
##  Default string of "Managed" is used if no script parameter is passed
if [[ "$4" != "" ]]; then
    orgName="$4"
else
    orgName="Managed"
fi

##  PARAMETER 5: Set to "no" (case insensitive) to show a single progress bar update for all installations.
##  Default value of "yes" will be used if no script parameter is passed
if [[ "$5" != "" ]]; then
    shopt -s nocasematch
    if [[ "$5" == "no" ]]; then

    else
        showProgEachUpdate="yes"
    fi
    shopt -u nocasematch
else
    showProgEachUpdate="yes"
fi

##  PARAMETER 6: Set the number of minutes until reboot (only used if installations require it)
##  Default value of 5 minutes is assigned if no script parameter is passed
##  Special note: Only full integers can be used. No decimals.
##  If the script detects a non whole integer, it will fall back on the default 5 minute setting.
if [[ "$6" != "" ]]; then
    ## Run test to make sure we have a non floating point integer
    if [[ $(expr "$6" / "$6") == "1" ]]; then
        minToRestart="$6"

        minToRestart="5"
    fi
else
    minToRestart="5"
fi

##  Parameter 7: Set to the full path of an icon or image file for any dialogs that are not using the
##  Apple Software Update icon. This could be a company logo icon for example
##  Default icon is set in the following manner:
##      If no script parameter is passed, or the icon/image can not be found and JAMF Self Service is present on the Mac, its icon will be used
##      If Self Service is not found, the Software Update icon will be used
if [[ "$7" != "" ]]; then
    if [[ -e "$7" ]]; then
        echo "A custom dialog icon was set: $7"
        msgIcon="$7"
    else
        if [[ -e "/Applications/Self Service.app/Contents/Resources/Self Service.icns" ]]; then
            ##  Self Service present. Use a default Self Service icon if the file specified could not be found
            msgIcon="/Applications/Self Service.app/Contents/Resources/Self Service.icns"
        else
            ##  Icon file not found, and Self Service not present. Set icon to Software Update
            msgIcon="$swuIcon"
        fi
    fi
else
    if [[ -e "/Applications/Self Service.app/Contents/Resources/Self Service.icns" ]]; then

        msgIcon="/Applications/Self Service.app/Contents/Resources/Self Service.icns"
    else

If you copy paste this into a text editor like TextWrangler or BBEdit, etc. the relevant lines are on line 29, which has forceEnableUpdates="yes" With the "yes" in there, it forces the updates to be selected by removing the checkboxes altogether. It will just show a list of the updates about to be installed.

If you want to remove the Cancel button from the dialog, then edit line 591, which is part of the startDialog2 function. Remove the --button2 " Cancel " text from that, which will remove the cancel button. You can also remove --cancel "button2" from line 592, just for cleanliness, but it's not strictly necessary.

Lastly, the if/then/else block that comes right after those lines includes an else part for if the user clicks Cancel, but it won't have any effect since there is only an "Install Now" button in the dialog. You could remove the else portion though if you wanted to.

Hope that helps and it works for you. Feel free to post back if you see any issues, but I can't guarantee how much time I will have to look it over for adjustments.

Thank you - i Will try with mojave :)

Captainamerica · ‎12-13-2018

Your corrections work very good. However, when I click install (on the update 10.14.2 for Mojave), the policy just finish without anything is installed. So seems like the installation process has some issues
Don´t know if there is a "quick fix" for this or you maybe know some different script that can be used for software update that inform the users

Thanks for your support

Captainamerica · ‎12-14-2018

@mm2270 Just checked the first script again called Selectable_SoftwareUpdate.sh works fine and is updating - but the 005 version seems to have somekind of "bug" since nothing happens what clicking install. So guess it must be somekind of difference. Have tried to compare the 2 scripts but quite difficult for me to find the area where the problem is. So if you have any time to take a look it would be great

Is there a way I can get a step by step 'how-to' on sending a simple popup message with an OK button to a students computer? I am some what familiar with Terminal, but I am not seeing a place in Jamf to send commands. Is this something I can administer from an admin pc on our network? or would I use a the jamf webapp? Any help would be much appreciated. Thank you.
