Mac has integrated VNC server so users don’t have to install VNC server on Mac in order to use VNC software or apps to control Mac from iPhone, iPad, Android, PC or another Mac. In this quick guide, we will show you how to use an iPhone or iPad to control a Mac through the Screen Sharing in OS X. By doing so, you can see anything displayed on your Mac right on your phone or tablet, you can get access to your Mac, the files, programs on your Mac as if you were sitting in front of your Mac. You can control the mouse remotely using your iPhone and type into your Mac using the virtual keyboard on your touch screen. Apple doesn’t include VNC support into iOS, but we have third-party VNC viewers thankfully, notably the VNC Viewer from RealVNC. Note that VNC Viewer is available for free from App Store. You can download it from previous linked page.
How to control Mac from iPhone or iPad using VNC Viewer?
On your Mac, click the Apple menu from its top menu bar, choose System Preferences from the drop-down menu. Then click Sharing in the System Preferences window, and click to enable the Screen Sharing. You will then find the status of Screen Sharing changes and the VNC server address. This is a your Mac’s IP address in the local network. If you need to access your Mac through the internet, you will need a dedicated public IP instead.
On your iPhone or iPad, make sure it is connected to the same WiFi as your Mac. Then launch the VNC Viewer app. You can go to the Bonjour from the side menu to let the VNC viewer automatically discover your Mac.
You can also go to add your Mac to the Address Book of the VNC viewer. You need to manually type in the VNC server IP address when you choose to manually add Mac to the Address Book of VNC Viewer on iPhone or iPad.
On the Address Book screen, tap on the Add button (+), then type in the VNC server address which you can find in the Screen Sharing on Mac. Give your Mac a name and save. You will be prompted for authentication with your Mac’s username and password when you connect.
Once the VNC session is established, you can use the iPhone or iPad to control over the Mac screen. For example, you can tap with one finger to left-click, pinch with two fingers to zoom, touch and drag to position the mouse cursor, double tap to double-click, tap with two fingers to right-click, tap to open the virtual keyboard and start typing, etc.
