How do I modify the "About _app name_"?

I can modify the toolbar thing on projectname.storyboard, but I can't find a way to edit the window that pops up when I click "About app name"
You can create an infoWindow in IB with the content you need.
Then connect the about Menu item to this IBAction:

Code Block
@IBAction fileprivate func showinfos(_ sender: NSMenuItem) {
infoWindow.makeKeyAndOrderFront(infoWindow)
infoWindow.isWindowVisible = true
// etc…
}

In this window, I also have a button (or a gesture on a label) to keep access to the standard About window, with version num and build num, through this IBAction:
Code Block
@IBAction func aboutVersion(_ sender: NSClickGestureRecognizer) {
NSApp.orderFrontStandardAboutPanel(self) // This is the default action to which About app is connected to
}

or
Code Block
@IBAction func aboutVersion(_ sender: NSButton) {
NSApp.orderFrontStandardAboutPanel(self) // This is the default action to which About app is connected to
}



What is it about that window you wish to edit, exactly?

Style, tint, size, border, contents, app's name only...?
