Hi and Welcome. My Name is ***** ***** I look forward to assisting you today with your question.
Could you please tell me what do you mean by tether ?
Do you want to download photos from your Nikon to your Mac ?
Do you mean Wireless or wired USB connection ?
There are mainly there ways to connect the Camera to download pictures to your Mac.
1 - By USB connection
2 - By connecting memory card to computer
3 - By using WiFi - For this, you have to buy an additional WiFi Adapter but you can only connect to Android or iOS device --> https://www.amazon.com/Nikon-Wireless-Mobile-Adapter-Digital/dp/B007VGGIB6
You can't keep it connected to Macbook Pro to automatically upload pictures you taken on it. You have to do this manually.
Method 1 is the best option to download photos to your Mac. Connect the camera to your Mac with the USB cable. Then go to Applications folder and open Image Capture. Image Capture will recognize the camera and show the pictures/videos in it. Select the pictures and videos you would like to download and download using it.
You can also use iPhoto or Photos to download and save Photos to your library of Mac.
If you have any questions or would like any additional information, please don't hesitate to ask.

Oh ok. I understand. There are no official apps from Canon that does this, but there are some third party applications that allow this tethering like this --> http://www.sofortbildapp.com/
But it doesn't support your model because of limitation in the software of camera.
There is another one, but it isn't available for Mac --> http://digicamcontrol.com/
There are some official apps are available for Android and iOS devices but not for Macs -->
(You will need to buy the wireless adapter to use your camera with that app)
