Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
What MAC OS X version is on your MacBook, is the first thing I have to ask - ?
And, Do any other devices prove usable on the USB C port(s) in question, that you are trying to get the StealthCam working with ?
Is the StealthCam camera new, or 1 year old, or older, please?
There is no information on MAC OS X version compatibility of your model that I have found yet, though cameras of this sort can be used with some MAC OS X systems. In case I locate such information, I must ask: What MAC OS X version is on your computer, pease?
