I am trying to get a stream from MacBook High Sierra webcam, mac does not have /dev/video0
is there any way to access MacOS webcam ?
I am programming in golang and I am using golang.org/x/sys/unix

You can use OpenCV bindings and get frame from camera.

Have a look at godoc for go-opencv

A short example:

index := 0 // example
camera := opencv.NewCameraCapture(index)

if camera.GrabFrame() {
    frame := camera.RetrieveFrame(1)
    img := frame.ToImage()
}
