I thought Blender would work the same on a Mac as it does on a PC, but I cannot seem to find the item 'dialogue boxes' that exist on the PC version. Anyone know how to bring up an item dialogue box in OSX version of Blender?
Press T to open the Toolbox.
N for the Properties
F6 to bring the poup-up (that shows the same options as the ones on the Toolbox).
If the keyboard shortcuts conflict with the ones in blender you can re-assign them using the User Properties (or better still by changing the preferences on your OS)
