Plug in your camera to your Mac, turn it on, open your Applications folder and start the program called Image Capture. Its main window has a left hand menu called DEVICES and another one called SHARED. The Devices menu will have your camera listed and you can bring in images to your drive.

Note: to be complete, you can set default folders and have scripts that do if-then tasks, etc. etc. but that is way beyond getting you up and running quickly
