Webcam doesn't work on OSX Sierra 10.12.6

Processing Libraries

I’m trying to capture my webcam in Processing, but it doesn’t work.
I’m using Processing 3.5.3 OSX Sierra 10.12.6

I used the code from the reference:

import processing.video.*;

Capture cam;

void setup() {
  size(640, 480);

  String[] cameras = Capture.list();
  
  if (cameras.length == 0) {
    println("There are no cameras available for capture.");
    exit();
  } else {
    println("Available cameras:");
    for (int i = 0; i < cameras.length; i++) {
      println(cameras[i]);
    }
    
    // The camera can be initialized directly using an 
    // element from the array returned by list():
    cam = new Capture(this, cameras[0]);
    cam.start();     
  }      
}

void draw() {
  if (cam.available() == true) {
    cam.read();
  }
  image(cam, 0, 0);
  // The following does the same, and is faster when just drawing the image
  // without any additional resizing, transformations, or tint.
  //set(0, 0, cam);
}

This is my Console output:

Changed waitThread to realtime priority!
Asked for format description...

I tried to outpute my list of devices with the following code, but the console outputs the same:

import processing.video.*;

Capture cam;
void setup(){
 size(600,600);
 background(255);
 println(Capture.list()); 
}

void draw(){
   println(Capture.list()); 
}

I’ve tried the code in other computers and it does work, I tried looking into System Preferences / Security & Privacy to see if there were options for camera permissions, but it doesn’t show anything.

Any help will be welcome.

Cheers!
