.TITLE
    Rotate macOS LAPS Passwords

.SYNOPSIS
    Rotates Local Administrator Password Solution (LAPS) passwords for macOS devices in Intune using Graph API.

.DESCRIPTION
    This script connects to Intune via Microsoft Graph API and rotates the LAPS passwords for managed macOS devices.
    The script retrieves all macOS devices from Intune and triggers LAPS password rotation for each device.
    It provides real-time feedback on the rotation process, handles errors gracefully, and generates detailed reports.
    The script supports filtering by device groups, individual devices, or processing all macOS devices.

.TAGS

.MINROLE

.VERSION
    1.5

.CHANGELOG
    1.5 - Treat test-mode and empty-target outcomes as normal runbook output instead of warning streams
    1.4 - Added Azure Automation contract validation, portal-safe boolean parameters, beta Graph endpoints, and terminating paging errors
    1.3 - Azure Automation now records script progress, outcomes, and summaries in job history
    1.2 - Confirmation prompt is now local-only: Azure Automation runs require -Force and exit with an error instead of hanging on Read-Host; rotation calls retry once after 60 seconds on throttling; results collection switched to a generic list
    1.1 - Local runs now use MgGraphCommunity for WAM-free interactive sign-in (auto-installed if missing); added DeviceManagementManagedDevices.PrivilegedOperations.All scope required by the Graph action (calls previously always failed with 403)
    1.0 - Initial release

.LASTUPDATE
    2026-07-30

.EXAMPLE
    .\rotate-macos-laps-passwords.ps1
    Rotates LAPS passwords for all macOS devices in Intune

.EXAMPLE
    .\rotate-macos-laps-passwords.ps1 -DeviceName "MacBook-001"
    Rotates LAPS password for a specific device

.EXAMPLE
    .\rotate-macos-laps-passwords.ps1 -DelaySeconds 5 -ExportReport "true"
    Rotates LAPS passwords with a 5-second delay between operations and exports results

.EXAMPLE
    .\rotate-macos-laps-passwords.ps1 -TestMode "true" -DeviceLimit 5
    Runs in test mode, processing only 5 devices without actual rotation

.NOTES
    - Requires Microsoft.Graph.Authentication module: Install-Module Microsoft.Graph.Authentication
    - LAPS must be configured and enabled for macOS devices in Intune
    - The rotation is triggered immediately but may take time to complete on the device
    - Personal devices cannot have their LAPS passwords rotated
    - The new password will be available in Intune after successful rotation
    - Local interactive sign-in uses the MgGraphCommunity module to avoid the Graph SDK's mandatory WAM broker on Windows
