Pan and orbit
Many users would like to use Apple’s Magic Trackpad in ArchiCAD but most of them miss the pan/orbit feature. Generally – using regular mice – these functions are controlled by the middle button of the mouse.
Fortunately there are 3rd party tools that can enable the middle click feature for trackpads – including Magic Trackpad.
MagicPrefs is one of these, you can set the two finger click as the middle button and from that point you can pan and zoom. Here is a screenshot showing the required setting:

Secondary – right click
You can enable the secondary click function is System Preferences, Trackpad, Point & Click. You can choose from three options as on the picture.
On Mac from OS X Lion the way of scroll is reversed to follow the evolution of the touch based interfaces. As a result in ArchiCAD the zoom also works that way. You can choose between the old and the new way in System Preferences, Trackpad, Scroll & Zoom
