Why the default UserAgent's platform is "Intel Mac" even in windows?

[kvii]

Rod Version: v0.116.2

The defaultDevice of a rod.Browser is devices.LaptopWithMDPIScreen.Landscape(), which is a device whose UserAgent's platform is mac, even in windows.

rod/browser.go

Lines 69 to 82 in 01a50b9

	func New() *Browser {
	return (&Browser{
	ctx: context.Background(),
	sleeper: DefaultSleeper,
	controlURL: defaults.URL,
	slowMotion: defaults.Slow,
	trace: defaults.Trace,
	monitor: defaults.Monitor,
	logger: DefaultLogger,
	defaultDevice: devices.LaptopWithMDPIScreen.Landscape(),
	targetsLock: &sync.Mutex{},
	states: &sync.Map{},
	}).WithPanic(utils.Panic)
	}

rod/lib/devices/list.go

Lines 615 to 632 in 01a50b9

	// LaptopWithMDPIScreen device.
	LaptopWithMDPIScreen = Device{
	Title: "Laptop with MDPI screen",
	Capabilities: []string{},
	UserAgent: "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/114.0.0.0 Safari/537.36",
	AcceptLanguage: "en",
	Screen: Screen{
	DevicePixelRatio: 1,
	Horizontal: ScreenSize{
	Width: 1280,
	Height: 800,
	},
	Vertical: ScreenSize{
	Width: 800,
	Height: 1280,
	},
	},
	}

So if a web site has some logic depend on navigator.userAgent, it will lead to an unexpected result in windows.

This mainly for the ability that running the same code will get the same result, no matter where it is. It's very helpful to reproduce problems. And the device can be changed. It's just a hard-code device setting.

As @ysmood's answer in discord. We need to change user agent manually in windows(how to). The current user agent in windows is "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/128.0.0.0 Safari/537.36".
