'If you are using a Mac, you don't have to download anything to check the shutter actuation count. Open the image with the Preview application. Then, from the Tools menu choose Show Inspector.

JK:-) I always check my camera when I buy refurbished cause I want a low count. I haven't been disappointed yet. It's been my understanding that they all get the data from the same source, so they will all either be correct or incorrect. That said, I haven't really paid attention to it, because as noted above, it really doesn't impact me unless I'm buying/selling used, and even then it's of limited value.
Canon doesn't provide a built-in way to view the shutter count. Nor do they include a utility that displays the shutter count. It's always a 3rd party method that has to be used to see it.
I use a utility called 'ShutterCount' available for Macs (via Mac 'App Store'). I think it was $2.99 USD. There is one caveat about the 6D. If WiFi is enabled then it blocks the apps ability to read the shutter count via USB cable. You'll need to disable the WiFi before using it (this also applies to the 70D.). Canon keep the software that determine the actual auction count only to themseleves and had it always. I remember a decade or so back, the only way to find out that number was to ask Canon's repair center.
Buy the way, this is a free service if you send your camera for any reason to them so don't forget to ask for it as it will be revealed to owner, upon request. Avoind that paid nasty software. It is written by a money griddy provider whose sole purpose is to get your money. Software has limitations and is only usable to one camera you first used it for. So if you have 10 camera bodies or need to just randomly check each potential camera you want to buy, you need to pay separatedly for each. There are many other free softwares out there that do a good and reliable count.
How To Find Shutter Count On Canon For Mac Download
There was one that was extremely easy to use with a good review on youtube but because it was offered from a server located in Iran, was removed from the face web for the obvious reasons and I wish I have a back up of that one. Anyhow there are plenety of free softwares and make sure you don't pay for gimmicks. And last words, if you need the most reliable count, ask it directly form Canon's repair service (For free) when you send you camera for anyother reason.
