Not only it just does not work - you have to hard reboot.
Make yourself a bog favor and run away from here. In my experience version 2 did not work and this one... Ive just connected v3 on OS X 10.2 (Macbook Pro 15 Late 2013 w/ thunderbolt display) and got a terrible glitch where I could do nothing on my Mac, thus had to hard reboot (with all the opened apps closing). The only thing this product is good at is making 15 Euro less one your bank account. Seems like people at Avatron do not know what testing is. Terrible.
