Hello @jacobgorm, did you find a way to disable it?

I found the reason/solution for this behavior.
You need to add an AVCaptureVideoDataOutput to your session.
On Mac you need to set the FPS on the AVCaptureVideoDataOutput too
#if os(OSX)
if let connection = videoDataOutput.connection(with: .video) {
connection.videoMinFrameDuration = CMTimeMake(value: 1, timescale: Int32(fps))
connection.videoMaxFrameDuration = CMTimeMake(value: 1, timescale: Int32(fps))
}
#endif
You need to change the AVCaptureSession.Preset. It defaults to high which I guess limits in an undocumented way the fps to 30. If you change it to hd4K3840x2160, hd1920x1080, ... it will run with the desired FPS.
I am really upset with the documentation from Apple. As a beginner it is really, really hard to debug problems like this. There is nowhere a hint, that the default profile high is limiting the "output" to 30 fps.
