macOS Background Execution - Menu Bar & Autostart

Overview

Complete implementation of macOS background execution features including system tray menu bar app and launch at login functionality for the Outsourced crypto community platform.

Features Implemented

1. System Tray (Menu Bar App)

• Tray icon appears in macOS menu bar
• Click to toggle window visibility (left-click on icon)
• Context menu with two options:
  • "Show/Hide Window" - Toggle window visibility
  • "Quit" - Exit application completely
• Window starts hidden on launch (background execution)
• Close button minimizes to tray instead of quitting app

2. Launch at Login (Autostart)

• LaunchAgent configuration for macOS
• Configurable autostart via plugin API
• Command-line flags support for launch arguments
• Native macOS integration using Launch Services

Implementation Details

Dependencies Added

Cargo.toml:

tauri = { version = "2", features = ["tray-icon", "macos-private-api"] }
tauri-plugin-autostart = "2"

Configuration Changes

tauri.conf.json:

{
  "app": {
    "windows": [
      {
        "visible": false, // Start hidden
        "decorations": true,
        "resizable": true,
        "center": true
      }
    ],
    "trayIcon": {
      "id": "main-tray",
      "iconPath": "icons/icon.png",
      "iconAsTemplate": true,
      "menuOnLeftClick": false,
      "tooltip": "Outsourced - Crypto Community Platform"
    },
    "macOSPrivateApi": true // Required for advanced tray features
  }
}

capabilities/default.json:

{
  "permissions": [
    "core:tray:default",
    "autostart:default",
    "autostart:allow-enable",
    "autostart:allow-disable",
    "autostart:allow-is-enabled"
  ]
}

Rust Implementation

Key Components:

1. Toggle Window Visibility - Helper function to show/hide main window
2. Setup Tray - Creates system tray with menu and event handlers
3. Window Close Handler - macOS-specific override to minimize instead of quit
4. Autostart Plugin - Configured with LaunchAgent for macOS

Code Structure (src-tauri/src/lib.rs):

// System tray with menu
fn setup_tray(app: &AppHandle) -> Result<(), Box<dyn std::error::Error>> {
    // Creates "Show/Hide Window" and "Quit" menu items
    // Handles left-click on tray icon to toggle visibility
    // Menu click events for show/hide and quit actions
}

// Main app setup
pub fn run() {
    tauri::Builder::default()
        .plugin(tauri_plugin_autostart::init(
            tauri_plugin_autostart::MacosLauncher::LaunchAgent,
            Some(vec!["--flag1", "--flag2"]),
        ))
        .setup(|app| {
            // Desktop-only tray setup
            #[cfg(desktop)]
            setup_tray(app.handle())?;

            // macOS-specific close behavior
            #[cfg(target_os = "macos")]
            // Override close button to hide instead of quit
        })
}

Platform-Specific Behavior

macOS

• Tray icon appears in menu bar
• Close button hides window (minimizes to tray)
• LaunchAgent for autostart integration
• Native macOS menu bar styling

Windows/Linux

• Tray icon in system tray
• Same menu functionality
• Platform-appropriate autostart mechanisms

Mobile (iOS/Android)

• Tray features disabled (desktop-only)
• Autostart not applicable on mobile

Usage

From Frontend (Future Integration)

Control autostart via Tauri commands:

import { invoke } from '@tauri-apps/api/core';

// Enable autostart
await invoke('plugin:autostart|enable');

// Disable autostart
await invoke('plugin:autostart|disable');

// Check if enabled
const isEnabled = await invoke<boolean>('plugin:autostart|is_enabled');

Tray Behavior

User Actions:

1. Left-click tray icon → Toggle window visibility
2. Right-click tray icon → Open context menu
3. "Show/Hide Window" → Toggle visibility
4. "Quit" → Exit application
5. Close window button → Hide window (macOS only)

Testing

Build & Test

# Clean build
cargo clean --manifest-path src-tauri/Cargo.toml

# Build debug app bundle (required for tray testing on macOS)
npm run tauri build -- --debug --bundles app

# Install to Applications
cp -R src-tauri/target/debug/bundle/macos/tauri-app.app /Applications/

# Launch and test
open /Applications/tauri-app.app

Verification Checklist

• Tray icon appears in menu bar
• Left-click toggles window visibility
• Context menu has "Show/Hide Window" and "Quit"
• Close button hides window (doesn't quit)
• Window can be shown again from tray
• Quit option properly exits app
• Window starts hidden on launch
• Autostart can be enabled/disabled

Build Requirements

macOS Deep Link & Tray Testing

• Must use .app bundle (not tauri dev)
• tauri dev does NOT support deep links or full tray functionality
• Use debug build: npm run tauri build -- --debug --bundles app

Cargo Cache Issues

If UI appears outdated after rebuild:

cargo clean --manifest-path src-tauri/Cargo.toml
npm run tauri build -- --debug --bundles app

WebKit Cache

Clear WebKit cache if needed:

rm -rf ~/Library/WebKit/com.openhuman.app
rm -rf ~/Library/Caches/com.openhuman.app

Configuration Options

Autostart Arguments

Customize launch arguments in lib.rs:

.plugin(tauri_plugin_autostart::init(
    tauri_plugin_autostart::MacosLauncher::LaunchAgent,
    Some(vec!["--minimized", "--silent"]),  // Custom flags
))

Tray Icon

Change tray icon path in tauri.conf.json:

{
  "trayIcon": {
    "iconPath": "icons/custom-tray-icon.png",
    "iconAsTemplate": true // Adapts to dark/light menu bar
  }
}

Window Behavior

Adjust window settings:

{
  "windows": [
    {
      "visible": false, // Start hidden
      "decorations": true, // Show title bar
      "resizable": true, // Allow resize
      "center": true // Center on screen
    }
  ]
}

Known Limitations

1. Menu bar icon styling - Uses template mode for dark/light theme adaptation
2. LaunchAgent delay - macOS may have slight delay before launching at login
3. Bundle requirement - Full functionality requires .app bundle, not tauri dev
4. Desktop-only - Mobile platforms don't support system tray

Future Enhancements

Potential improvements for future development:

1. Settings Integration - Add autostart toggle in settings modal
2. Notification Support - Show notifications from tray
3. Quick Actions - Add more tray menu items
4. Status Indicators - Show connection status in tray icon
5. Tray Tooltip - Dynamic tooltip with app status

Security Considerations

macOS Private API

• Required for advanced tray features
• Approved by Apple for this use case
• No App Store restrictions for direct distribution

LaunchAgent

• Installed in user's LaunchAgents directory
• User can disable via System Settings
• Respects macOS security policies
