[v2, mac] Could not create transparent window

[icaliskanoglu]

Description

I am trying to create a transparent background application. It is working in linux and windows as expected but it is not transparent for macOS. Here is the configuration:

	err = wails.Run(&options.App{
		Width:            512,
		Height:           512,
		BackgroundColour: &options.RGBA{R: 0, G: 0, B: 0, A: 0},
		Mac: &mac.Options{
			WebviewIsTransparent: true,
			WindowIsTranslucent:  true,
		},
		Linux: &linux.Options{
			WindowIsTranslucent: true,
		},

		Frameless: true,
		AssetServer: &assetserver.Options{
			Assets: assets,
		},
		OnStartup: app.startup,
		Bind: []interface{}{
			app,
		},
		AlwaysOnTop: true,
	})

To Reproduce

1. wails init -n test -t react
2. cd test
3. open main.go
4. add Mac Options to options.App
5. wails dev

Mac Options:

Mac: &mac.Options{
			WebviewIsTransparent: true,
			WindowIsTranslucent:  true,
		},

Expected behaviour

Based on the document , I am expecting the window should be transparent.
