I would highly recommend the Elgato Video Capture, but not for El Capitan. Unfortunately, Elgato does not warn you via their website that this product won't work with El Capitan, and I think they really should. I switched back to Mavericks, and now the Video Capture device works perfectly again. They suggested going back to Yosemite OS or Mavericks. In communicating with Elgato technical support, and after they remotely analyzed my Video Capture device plugged into my Macbook Pro, they told me that El Capitan changes the USB configuration and interferes with their device. The picture would often freeze during recording etc. Audio was either over-recorded to distortion levels, or missing entirely.
Then I upgraded my OS to El Capitan, and everything went haywire. Product worked very well, easy and intuitive to use. Verified Buyer Reviewer: Anonymous Location: Carlsbad, CA Age: 55-65 Experience Level: Home User Owned Product: 1-3 months Rating: 4/5 Great, But not for El Capitan NovemPurchased Elgato Video Capture about a month ago, and originally started using it with the Mavericks OS. Elgato's Video Capture does just that.". Improved scaling of small overlay images for Stream Command.
Video no longer freezes in 3rd party applications when setting custom resolution or frame rate for Game Capture HD60 Pro and HD60 S. User interface of Sound Capture is corrrectly drawn on high dpi displays now.
