Stream from your iPhone or iPad or iPod Touch to your Mac
The Netflix app for iOS supports AirPlay, a proprietary protocol stack developed by Apple, which allows wireless streaming between devices of multimedia content. This means that you can stream Netflix movies and shows from your iOS devices to any AirPlay-enabled devices over local Wi-Fi. And because the app also supports offline downloads, you have everything you need to enjoy Netflix offline on your Mac. Well, almost everything. You also need an app like AirServer so you can receive AirPlay streams on your Mac.
The easiest and proven solution is to access Netflix via Google Chrome browser on your Mac as @Nimesh Neema explained. You can even stream to any TV using Chromecast in Google Chrome browser and with $35 Cast dongle device (at any best buy) that plugs into any TV with HDMI plug.
