Is it that your mac doesn't detect the 7D II ... or is it that the mac doesn't automatically launch a program to import pictures when the camera is connected.
These two different things (I know it seems subtle) would be completely different problems.
If you want a program to automatically be launched when you attach a camera, there are a few ways to do it. Apple's own photo software (Photos and Aperture) both have options that let you indicate if they should automatically launch when a camera is connected.
However a more universal way is to use Apple's "Image Capture" program (it's in your Applications folder and it's something you've probably never ued before.) Launch this and connect your camera. In the lower left corner is a tiny triangle (probably the pointy end of the triangle is pointing up). Click that triangle and it should open a window which reads: "Connection this camera opens:" with a selection item that lets you pick an application. You can literally pick ANY application you want. You'll see all the Apple programs that can handle the camera... but suppose you want to auto-launch Lightroom... just pick 'other' and then it'll open a file selection window and you can navigate to the Lightroom application and set that.
Having done this, when you connect your camera in the future, it'll auto-launch whichever program you picked.
I personally have a few programs I use... from EOS Utility to LIghtroom to Kuvik Capture and even a few others... so I dislike having one particular program auto-launch. So on my personal mac I set the choice to "no application" and I manually launch whatever application I need to use.
