+# macOS Intune Toolkit Changelog
+
+## 2026-04-13 — API Permissions Sync for `Initialize-IntuneAuth.ps1`
+
+### Modified
+- **`Scripts/Initialize-IntuneAuth.ps1`**
+  - Unified the required Microsoft Graph application permissions into a single `$requiredRoles` list defined before app creation/reuse logic:
+    - `DeviceManagementApps.ReadWrite.All`
+    - `DeviceManagementConfiguration.ReadWrite.All`
+    - `DeviceManagementManagedDevices.ReadWrite.All`
+    - `DeviceManagementScripts.ReadWrite.All`
+    - `DeviceManagementServiceConfig.ReadWrite.All`
+    - `DeviceManagementRBAC.ReadWrite.All`
+    - `Group.ReadWrite.All`
+    - `Directory.Read.All`
+    - `User.Read.All`
+    - `Organization.Read.All`
+    - `Policy.ReadWrite.ConditionalAccess`
+    - `Agreement.ReadWrite.All`
+    - `CloudPC.ReadWrite.All`
+    - `Application.Read.All`
+  - **Existing app patching**: When reusing an existing app registration, the script now inspects its current `RequiredResourceAccess`. If any required permissions are missing, it patches the app via `Update-MgApplication`, refreshes the local app object, and the downstream admin-consent loop automatically grants consent for the newly added roles.
+
+---
+
+## Prior delivered changes (context summary)
+
+### New scripts added
+- `Scripts/Bulk-AppAssignment.ps1` — bulk-assign apps to groups/All Users/All Devices
+- `Scripts/Bulk-AssignmentManager.ps1` — add/remove assignments for any policy type using correct `@odata.type` and bulk `/assign` endpoint
+- `Scripts/Backup-Restore-Assignments.ps1` — JSON backup with cross-tenant group name resolution
+- `Scripts/Export-AssignmentsToCsv.ps1` — CSV and Markdown documentation output
+- `Scripts/Bulk-RenamePolicies.ps1` — search/replace, add/strip prefix across displayName/description
+- `Scripts/Bulk-DeviceOperations.ps1` — delete/retire/wipe/lock/sync with `-WhatIf` safeguards
+- `Scripts/Start-IntuneToolkit.ps1` — unified reverse-numbered `fzf`-based launcher
+- `Scripts/Initialize-IntuneAuth.ps1` — one-time Entra app + secret + Keychain setup
+
+### Core / Extensions / Headless changes
+- **`Extensions/MSGraph.psm1`**
+  - `Invoke-GraphRequest` now throws on 4xx/5xx HTTP errors (was silently returning null)
+  - Added `-AllPages` support to `Get-GraphObjects` and toolkit queries for large tenants
+- **`Headless/IntuneManagement.Headless.psm1`**
+  - Expanded `Get-DefaultIntunePolicyObjectTypes` to ~45 types, including `DeviceManagementIntents`
+  - Threaded `NameSearchPattern` / `NameReplacePattern` through export/import/action flows
+- **Settings Catalog fixes**
+  - Uses `name` property instead of `displayName` for queries/labels
+  - Assignments use `#microsoft.graph.deviceManagementConfigurationPolicyAssignment` and the bulk `POST …/assign` endpoint
+- **TUI / `fzf`**
+  - Spacebar toggle, Esc to go back, reverse numbering (10→1) in unified launcher

+# Agent Operations Log
+
+## Session: 2026-04-13T13:31:37+02:00
+
+### Task
+Update `Initialize-IntuneAuth.ps1` to ensure the Entra app registration is granted all Microsoft Graph permissions required by the expanded macOS Intune Toolkit, and log all operations.
+
+---
+
+## Operations performed
+
+1. **ReadFile**
+   - Path: `/Users/avedelphina/Local/IntuneManagement/Scripts/Initialize-IntuneAuth.ps1`
+   - Line offset: `140`, Lines: `60`
+   - Purpose: Inspect the existing roles array and app creation logic.
+
+2. **StrReplaceFile**
+   - Path: `/Users/avedelphina/Local/IntuneManagement/Scripts/Initialize-IntuneAuth.ps1`
+   - Change: Replaced the inline `$roles` array + app creation block with a unified `$requiredRoles` list and added logic to patch missing permissions into an existing app registration via `Update-MgApplication`.
+   - Impact: New apps get the full permission set; existing apps are updated if roles are missing.
+
+3. **Grep**
+   - Path: `/Users/avedelphina/Local/IntuneManagement/Scripts/Initialize-IntuneAuth.ps1`
+   - Pattern: `New-MgServicePrincipalAppRoleAssignment`
+   - Purpose: Verify the downstream admin-consent loop would pick up updated roles.
+
+4. **ReadFile**
+   - Path: `/Users/avedelphina/Local/IntuneManagement/Scripts/Initialize-IntuneAuth.ps1`
+   - Line offset: `220`, Lines: `50`
+   - Purpose: Inspect the consent-granting region around `New-MgServicePrincipalAppRoleAssignment`.
+
+5. **Grep**
+   - Path: `/Users/avedelphina/Local/IntuneManagement/Scripts/Initialize-IntuneAuth.ps1`
+   - Pattern: `\$roles`
+   - Purpose: Confirm no stale `$roles` references remained after the refactor.
+
+6. **Shell**
+   - Command: `pwsh -Command "$ErrorActionPreference='Stop'; Get-Command /Users/avedelphina/Local/IntuneManagement/Scripts/Initialize-IntuneAuth.ps1 | Out-Null; Write-Host 'Syntax OK'"`
+   - Result: Syntax OK (PowerShell parsed the script without errors).
+
+7. **Shell**
+   - Command: `cd /Users/avedelphina/Local/IntuneManagement && git diff -- Scripts/Initialize-IntuneAuth.ps1`
+   - Result: No diff output (file is untracked in git).
+
+8. **Shell**
+   - Command: `cd /Users/avedelphina/Local/IntuneManagement && git status --short`
+   - Result: Listed modified and untracked files, confirming `Scripts/Initialize-IntuneAuth.ps1` is `??` (untracked).
+
+9. **WriteFile**
+   - Path: `/Users/avedelphina/Local/IntuneManagement/CHANGELOG_macOS_IntuneToolkit.md`
+   - Content: High-level changelog of the permissions update and prior context.
+
+10. **WriteFile**
+    - Path: `/Users/avedelphina/Local/IntuneManagement/OPERATIONS_LOG.md`
+    - Content: This file.

+<#
+.SYNOPSIS
+One-time setup helper for IntuneManagement headless authentication.
+
+.DESCRIPTION
+Creates a Microsoft Entra app registration (or reuses an existing one),
+adds required Microsoft Graph permissions, creates a client secret, and
+stores credentials securely:
+  - TenantId and AppId are saved to the JSON settings file.
+  - Client secret is saved to the macOS Keychain (default on macOS).
+
+Requires: Microsoft.Graph.Authentication, Microsoft.Graph.Applications
+Install if missing: Install-Module Microsoft.Graph -Scope CurrentUser
+
+.PARAMETER TenantId
+The Microsoft Entra tenant ID (GUID). If omitted, the script reads from
+existing settings or prompts interactively.
+
+.PARAMETER DisplayName
+The display name for the app registration. Default: IntuneManagement-Headless.
+
+.PARAMETER SettingsFile
+Path to the JSON settings file. If omitted, defaults to the macOS_IntuneManagement
+settings folder (~/Library/Application Support/macOS_IntuneManagement/Settings.json).
+
+.PARAMETER Force
+Recreate the app registration and secret even if existing credentials are found.
