If you’re an iPhone user who wants to use your MacBook as your primary computer, there are a few things you need to do first. Here’s how to cast your iPhone to your MacBook so you can work seamlessly between the two devices. First, make sure that both your devices are on the same network and have the same Wi-Fi connection. Next, open up the Settings app on your iPhone and go to General > Accessibility > VoiceOver. Under “Speech Recognition,” make sure that “Cast Screen/Audio” is enabled. Now, on your MacBook, open up the System Preferences app and click on Display. Under “Screen Sharing,” make sure that “Cast Screen/Audio” is enabled and select your iPhone from the list of available devices. You’ll now be able to see everything on your iPhone’s screen in real time on your MacBook’s screen! ..
