Use your Fujifilm camera as a webcam on macOS via USB

Just saw a video on using Fujifilm cameras as a web cam on Apple computers. Basically the steps are:

  1. Download and install Camera Live app on Github
  2. Download and install CamTwist Studio
  3. Run a command on your Mac via Terminal on the app you want to use the camera on
  4. Setup your Fujifilm camera
  5. Connect and go

Here are some tips on each of the steps:

  1. I’ve tested version 13 alpha on macOS 10.15.5
  2. I’ve tested version 3.4.3 on macOS 10.15.5
  3. The command to run in Terminal is
    “sudo codesign –remove-signature /Applications/<name of app>”
    I’ve tested this with Skype. Others are reporting that it works fine with Zoom.  For Skype, the command would be:
    “sudo codesign –remove-signature /Applications/Skype.app”
  4. Set camera to photo, not video, mode;
    In Connection Settings, select USB TETHER SHOOTING AUTO;
    Set camera to manual focus, and focus (You can try setting Pre-AF to On);
    Set exposure to manual and dial it in, check how it looks in Live View.
  5. Connect USB cable between camera and Mac;
    Start Camera Live app and select the Fuji camera (see image below);
    Start the CamTwist Studio app and select Syphon as the video source, and Camera Live in the Syphon server dropdown menu (see image below);
    Start the app you want to use the camera with eg Skype, and choose CamTwist as the camera (see image below).
