I came across this thread (https://exiftool.org/forum/index.php/topic,5171.msg24926.html#msg24926) in these forums, and as it's a bit old, I thought I'd make a new one.
You can read the shutter count data for this and other Canon cameras on OS X or Linux computers with the command-line utility gphoto2 (http://www.gphoto.org).
Plug in your camera, turn it on and at the command line type:
gphoto2 --get-config /main/status/shuttercounter
and it will return something like:
Label: Shutter Counter
Type: TEXT
Current: 8375
You can get a list of what stuff you can get/set with:
gphoto2 --list-config
but be careful -- you're "root" in your camera.
