Know Your Shutter Count with the Aptly Named "ShutterCount" Software for Mac

From ShutterCount:

ShutterCount displays the number of shutter actuations (the shutter count) of Canon EOS digital cameras and is developed exclusively for Mac users.

The shutter count is read directly from a USB-connected camera, and thus provides accurate numbers that are not attainable with simple EXIF-based methods.

Using this application you are no longer required to visit a Canon Service Center to read out the exact shutter count, thus saving you time and money. In addition to that, ShutterCount provides unlimited readings for an unlimited number of cameras.

The app supports the following cameras:

• Canon EOS-1D X
• Canon EOS 5D Mark II
• Canon EOS 5D Mark III
• Canon EOS 6D
• Canon EOS 7D
• Canon EOS 60D
• Canon EOS 70D
• Canon EOS 100D / Rebel SL1
• Canon EOS 600D / Rebel T3i / Kiss X5
• Canon EOS 650D / Rebel T4i / Kiss X6i
• Canon EOS 700D / Rebel T5i
• Canon EOS 1100D / Rebel T3 / Kiss X50
