If you are a Mac user and have a few Macs on your network, then you will probably be used to seeing other Macs in the network automatically show up in the Finder, so that you can log on to them and browse the file system or even remote control them.
The screen sharing feature of Macs uses VNC, so if you already have TightVNC server installed (as we do) then with a bit of configuration, we can get it to be recognized by other Macs on the network.
The tutorial here: http://4dc5.com/2012/06/12/setting-up-vnc-on-raspberry-pi-for-mac-access/ explains how to do this. It also includes the installation of TightVNC server, which you do not need to repeat as we already have that.
Once its all set up, you will be able to connect to the file system of your raspberry Pi.
Remember to change the user field to pi and as usual the default password is 'raspberry'.
If you click on the Share Screen button, you will get another login prompt.
This time, the password is the password you set up for the VNC server – I suggested 'raspberr'. That is with the 'y' missing from the end.
You should then get a VNC window using the Mac's built-in VNC viewer.
