  2. In this Payload, please search and replace “PUT YOUR LICENSE HERE” with the License key from your Crowdstrike portal.

  3. Follow our guide on how to add the Custom Payload in the Device Profile & deploy it to devices.

  4. On the device, you should see the following custom payload in the Profiles section in System Preferences.

Notes:

  1. The Payload and its contents are sourced from various albeit authenticated Apple Developer communities and forums.

  2. Please validate them on a test machine before deploying them on all your managed devices.

  3. Scalefusion has tested these Payloads, however, Scalefusion will not be responsible for any loss of data or system malfunction that may arise due to the incorrect usage of these payloads.

Step 2: Installing the software using the script.

  1. Create a file on your desktop, for example, DownloadAndInstallCrowdStrike.sh and open it in a text editor like notepad++

  2. Copy the contents below to the file or click here to download the file.

    #!/bin/bash
    
    #Create variable with download url of the installer
    DownloadUrl="ENTER_DOWNLOAD_URL"
    #Create variable with app name
    AppName='Falcon'
    #License Key
    LicenseKey="ENTER_LICENSE_KEY"
    #Write content of variable to console output
    echo "App Name: $AppName"
    
    echo "Testing to ensure App is not already installed"
    #Create variable with results of search in Application folder for $AppName
    ExistingSearch=$(find "/Applications/" -name "$AppName")
    #If variable is not null (If search found the app in the application folder)
    if [[ -n "$ExistingSearch" ]]
    then
        echo "$AppName already present in /Applications folder, exiting."
        exit 1
    else
        # Runs if app name wasn't found in application folder
        echo "$AppName not present in /Applications folder, installing"
        
        # Check if the CrowdStrike profile is present
        echo "checking to see if the CrowdStrike profile is present"
        # variable containing the installed profiles on the device
        ProfileSearch=$(profiles list -output stdout-xml)
        # Team identifier of CrowdStrike
        ProfileCompare="X9E956P446"
        # If statement that checks whether or not the CrowdStrike profile is installed
        if [[ $ProfileSearch = *"$ProfileCompare"* ]]
        then
            echo "The CrowdStrike profile is present, installing CrowdStrike Falcon"
            # Install CrowdStrike
            #download installer from S3 bucket and output it to /tmp folder
            curl "$DownloadUrl" --output /private/tmp/FalconSensorMacOS.pkg
            #Run the installer
            installer -verboseR -package /private/tmp/FalconSensorMacOS.pkg -target /
            # Activate Falcon with our license
            echo "Licensing app..."
            /Applications/Falcon.app/Contents/Resources/falconctl license "$LicenseKey"
            echo "Install finished, deleting install files..."
            #delete left over installation files no longer needed
            rm /private/tmp/FalconSensorMacOS.pkg
            echo "The following files were deleted: /private/tmp/FalconSensorMacOS.pkg" 
            echo "displaying agents stats: (if blank agent isn't running)"
            /Applications/Falcon.app/Contents/Resources/falconctl stats agent_info
        else
            echo "The CrowdStrike profile is NOT present, CrowdStrike Falcon will NOT be installed."
        fi
    fi
  3. In the script, set the values for the following properties:

    1. DownloadUrl: You will find the url to download the Crowdstrike falcon app from the Crowdstrike portal.

    2. AppName: Will be Falcon.

    3. LicenseKey: You will get the license key from your Crowdstrike portal.

  4. Once the above values are set, upload the script into the Enterprise store and set “Run Script as signed-in user” to NO.

  5. Follow our guide to upload & publish the Shell script using Scalefusion Dashboard.

Please note that to use the Shell scripts, the Scalefusion MDM Client Application must be installed on the device(s). Please follow our guide to publish and install the Scalefusion MDM Agent Application.
