I dug out my old iMac to connect to the USB 2.0 ports. I was hesitant due to some reviews, but I found it simple and easy to use. This mac is using OS X 10.9.5. I hooked up the device to my Mac and VHS player, then I opened QuickTime to screen record and it immediately recognized the device and i began recording. Very simple! I have transferred a few hours of VHS tapes so far with no issues.
