# 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**:

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

### Configuration Changes

**tauri.conf.json**:

```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**:

```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`):

```rust
// 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:

```typescript
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

```bash
# 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:

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

### WebKit Cache

Clear WebKit cache if needed:

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

## Configuration Options

### Autostart Arguments

Customize launch arguments in `lib.rs`:

```rust
.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`:

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

### Window Behavior

Adjust window settings:

```json
{
  "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
