MacOS not asking for permission to show notifications

Describe the bug

If I create and show a notification on my Mac, it shows an osascript commandline created notification. Confusing, because the icon is different from my app and, more problematic, it contains an 'open' button which opens an empty 'Script editor' folder when clicked...

Looking at the code I find this a fallback method for showing notifications.

I did not understand why the fallback was shown because the code is explicitly first asking for permission and if allowed should show normal notifications.

Looking in the app log I find this:

So it seems the app is not properly setup to ask for permission?

I found this Apple document that might relate to this:
https://developer.apple.com/documentation/bundleresources/entitlements/com_apple_developer_aps-environment

It says To add this entitlement to your app, enable the Push Notifications capability in Xcode.. So I assume this requires a change in the xcode project that is used for building darwin apps.

How to reproduce

Create a minimal notification app. Build for darwin and run on MacOS.

Example code

func main() {
	a := app.New()
	w := a.NewWindow("Notification Example")
	btn := widget.NewButton("Show Notification", func() {
		notification := fyne.NewNotification("Notification Title", "This is the notification.")
		a.SendNotification(notification)
	})
	w.SetContent(container.NewVBox(
		widget.NewLabel("Click the button to show a notification."),
		btn,
	))
	w.ShowAndRun()
}

Sadly this is due to Apples enforcement policies. We cannot show a native notification unless the app has been packaged and run through the app launcher.

It will follow the standard process of shipped via the store or a package, or installed using "fyne install".

Hmmm, fyne install does not support darwin? I tried the latest v2.4.5. Instead I used fyne release. If I install the app after that, a notification is shown, but only once. Even if I allow notifications.

[andydotxyz]

Fyne install does support Darwin. It supports all the platforms we build for.

If for some reason you are not seeing follow-up notifications please open an issue, this is not a known problem.

Fyne install does support Darwin. It supports all the platforms we build for.

The install help says:

 OPTIONS:
   --target value, --os value    The mobile platform to target (android, android/arm, android/arm64, android/amd64, android/386, ios, iossimulator).
   --installDir value, -o value  A specific location to install to, rather than the OS default.
   --icon value                  The name of the application icon file.
   --use-raw-icon                Skip any OS-specific icon pre-processing (default: false)
   --appID value, --id value     For Android, darwin, iOS and Windows targets an appID in the form of a reversed domain name is required, for ios this must match a valid provisioning profile
   --release                     Enable installation in release mode (disable debug, etc). (default: false)
   --help, -h                    show help (default: false)

So it explicitly says only mobile platforms.

If I do fyne install --os darwin it says `Unsupported target operating system "darwin"'.

Yikes! Docs need updated. What it means is you can install to current OS or one of the mobile platforms.

Don't pass an os parameter and it will install on the current OS
