Hi all,

 

Many of our users have less than 12 gb of free space remaining on HDD. Thus, no OS upgrade is possible and SSD performance is impacted.

Is there a way to display a popup to concerned users to make a data cleanup ?

Thanks

    Hi, @Eskobar 

    1st I would create a smart computer group with criteria "Drive Capacity MB" (you'll find it at the advanced criteria) less than *whatever you want in Megabyte*

    Then you have 2 options:

     

    - you can run an action right out oft this smart group (for example send an email)

    - you can create a policy, that will show a messagebox on the computers in that group with a text. You have to scope that policy to the smart computer group

    - either you will do this message box via an own script or you can configure the message at the policy itself at the "user interaction". I use an own script for this. (I did a script "message4u" with parameters for a headline and a text area, see my screenshots below)

    Hi  

    This awesome ! 

    Would you please share  "message4u"  script for the policy ?


    Here it is, hope it will help you to solve your question:

    #!/bin/bash

    if [ -z "$4" ]; then
    echo "no text specified, ending without a message" && exit 0
    else
    # sudo jamf -displayMessage -message "$4" && exit 0
    echo "set ddr to display dialog \\"$5\\" with title \\"$4\\" buttons {\\"accept\\"} default button \\"accept\\" " | osascript -
    fi

     

    Variable $4 is the text inside the message box, variable $5 is the title. The title is not mandatory, but without a message, there is no sense to pop up a message popup ;) Because of this I only ask for the text variable $4.

    This is what I use

     

    #!/bin/sh # Display free space FreeSpace=$( /usr/sbin/diskutil info / | /usr/bin/grep -E 'Free Space|Available Space|Container Free Space' | /usr/bin/awk -F ":\\s*" '{ print $2 }' | awk -F "(" '{ print $1 }' | xargs ) FreeBytes=$( /usr/sbin/diskutil info / | /usr/bin/grep -E 'Free Space|Available Space|Container Free Space' | /usr/bin/awk -F "(\\\\\\(| Bytes\\\\\\))" '{ print $2 }' ) DiskBytes=$( /usr/sbin/diskutil info / | /usr/bin/grep -E 'Total Space' | /usr/bin/awk -F "(\\\\\\(| Bytes\\\\\\))" '{ print $2 }' ) FreePercentage=$(echo "scale=2; $FreeBytes*100/$DiskBytes" | bc) diskSpace="Disk Space: $FreeSpace free (${FreePercentage}% available)" ## Information ## displayInfo="---------------------------------------------- Your Disk Space is Running Low $diskSpace Whatever you want here ----------------------------------------------" ## Disk Space Message ## diskmsg="button returned of (display dialog \\"$displayInfo\\" with title \\"Disk Space\\" with icon file posix file \\"/System/Library/CoreServices/Diagnostics Reporter.app/Contents/Resources/AppIcon.icns\\" buttons {\\"OK\\"} default button {\\"OK\\"})" clickedButton=$( /usr/bin/osascript -e "$diskmsg" ) ## Run additional commands ##### exit 0

    I've been using some of this code for a disk report of my own.
    I'm seeing a suite of M1 Mac Mini's bork out around:

    FreeSpace=$( /usr/sbin/diskutil info / | /usr/bin/grep -E 'Free Space|Available Space|Container Free Space' | /usr/bin/awk -F ":\\s*" '{ print $2 }' | awk -F "(" '{ print $1 }' | xargs )


    The error's I get look like...

    DISK SPACE REPORT /Library/Application Support/JAMF/tmp/MacOS - Student Device Report: line 27: 2847: Memory fault /Library/Application Support/JAMF/tmp/MacOS - Student Device Report: line 28: 2850: Memory fault /Library/Application Support/JAMF/tmp/MacOS - Student Device Report: line 29: 2853: Memory fault /Library/Application Support/JAMF/tmp/MacOS - Student Device Report: line 30: 2858: Memory fault /Library/Application Support/JAMF/tmp/MacOS - Student Device Report: line 31: 2860: Memory fault /Library/Application Support/JAMF/tmp/MacOS - Student Device Report: line 31: 2862: Memory fault /Library/Application Support/JAMF/tmp/MacOS - Student Device Report: line 31: 2864: Memory fault

    (Line 27 is where the highlighted code begins).

    Very strange!
    The code works wonderfully on all other devices - just seems to be falling over on M1 when run at check-in by the management account. If I send the commands direct via ARD, I get the expected result.

    Thanks all

    @YanW I guess that it's helpful for the user to add one more line at the end of the script to open Storage, in System Settings in macOS Ventura automatically: 

    open x-apple.systempreferences:com.apple.settings.Storage
