Can Mac OS X Lion (10.7 or better) be used

With v 3.0, it is possible to use Mac sign on, and therefore get around the buggy sign on page in Mac Screen sharing.

Is there a limit to the server screen size

V 1.1 has been tested with screen size 3200x3200. Such a size or larger is not recommended, as to the size of data needed to be send to the Client. One single screen 3200x3200 is 30 M byte, if send uncompressed!

It is not supported.

How to use dynamic IP address

If your VNC server does not have a fixed IP address or name, a solution could be a dynamic DNS name from a service as NO-IP The basic version of the service is free.

How to connect to your PC/Mac from the Internet

To allow a connection with the iPhone on the EDGE network or another wifi network, maybe at your local Cafe, you must configure the router/firewall protecting your Home network to allow traffic on port 5900. This could be a security risk! Read the router manual for advice. An example: I have a router at my house, which connect to the Internet. It has IP address on the Internet. The router has a fixed IP address on the Internet. If your internet provider (ISP) offers a dynamic address, a solution could be to use a service as NO-IP Click here to see your current router IP address.

    The router must also be configured to forward port 5900 traffic to your Mac/PC. To open port 5900 could be a security risk. Check the router manual for advice.

Program crash, when tapping mouse or keyboard icons

The iPhone is low on program memory. Reboot the iPhone. Also notice , using a server screen larger than 2000x2000 will give memory problems. In v 2.2 , it is possible to enable memory warnings in menu - edit connections.

Cannot make a connection to the Server

As a start make sure you have installed a VNC Server on your PC, or if using Mac OS X, has enabled the screen sharing.

  • The VNC Server has not been started
  • A firewall stopping access on port 5900. A firewall may run on the PC/Mac
  • Have installed PeerGuardian on the Mac/PC, and configured it to block some IP addresses.
  • The iPhone/iPod is not on the same network as the VNC Server. If using wifi, check wifi is enabled on the iPhone and not only the EDGE network. Also it is the same wifi network as your PC/Mac , and not your neighbors network.
  • If the iPhone is not using wifi, but only the EDGE network, the IP address for the VNC Server given in Mocha VNC must be your Home router IP address.

The vnc server in read only mode. (view mode, it is also called). Must be solved in the VNC Server configuration, not in mocha vnc.

Screen does not refresh

If the screen is large, and/or the network slow, it can take some time to refresh. Mocha VNC has in menu (+) icon, a refresh option, but it should not be needed for normal use. Using Refresh will just make it more slowly, as it requests the full Server screen to be send again.
Some VNC Servers can have problems with refresh. If problems is seen with a VNC Server and it is not a beta version, please write a mail to our support function. Include full VNC server name, version and OS type.

In X11 type VNC Servers used on Linux/UNIX systems it is possible to use displays. port = display + 5900
Display 0 = 5900
Display 1 = 5901
Display 2 = 5902
The port number can be configured in mocha vnc , connect window.

Host has closed the session

If this message is shown, at the negotiation, it could be
  • A firewall on the PC/Mac stopping port 5900 access
  • Wrong VNC Password. Check if it is the same on the Server and Mocha VNC<
  • If using a Mac, (x) all users must be selected. See How to configure VNC on Mac OS X
  • If using a Mac, the 32 bit color option must be enabled (connect dialog in Mocha VNC)
  • If using UltraVNC, notice MS Logon supported is not supported in Mocha VNC

How to get a faster display

  • Configure the desktop with a smaller screen. A screen size around 1000x1000 gives a good result
  • Use 8 bit color mode (connect window). Mac OS X Remote Management supports only 32 bit, and will fail in 8 bit mode
  • Use wifi and not the phone network
  • If using a Windows or Linux PC, try different VNC Servers. RealVNC in paid mode could be a good choice

How do I get a VNC Password

Depends on your Server type. If it is Mac OS X, see our Mac OS X page.
If it is a PC, you must first install a VNC Server on the PC. Try RealVNC for Windows and Linux

Vnc Mac Iphone

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.
