macOS Finder Integration

WinXMerge includes a Finder Sync Extension that adds right-click compare actions to macOS Finder.

Setup

1. Build the .app bundle with the Finder extension:

   ./scripts/build-macos-bundle.sh

2. Move WinXMerge.app to /Applications
3. Enable the extension in System Settings → General → Login Items & Extensions

Usage

Compare Two Files

1. Select 2 files in Finder
2. Right-click → Compare with WinXMerge
3. Opens a 2-way diff view

Compare Three Files

1. Select 3 files in Finder
2. Right-click → Compare with WinXMerge
3. Opens a 3-way merge view

Mark and Compare

1. Right-click a file → Mark for Compare
2. Navigate to another file
3. Right-click → Compare with [marked file]

Integration with Running Instance

If WinXMerge is already running, the Finder extension adds a new tab in the existing window instead of launching a new instance.
