There is slow pace to match with new OS. There is no version for Mac.
Whatever you do, do not install the Winfast PVR2 software into a win 7 64 bit O/S as when I did on my PC it completely destroyed the win 7 O/S by making the keyboard useable by not doing what the function of keys were.
You cannot uninstall this software - DO NOT use it - I had to do a complete reinstall of win 7 to get my PC working again.
BE WARNED this is not compatible with Win 7 64 bit from my experience.

Thanks for the warning. I'm still using it on Windows XP and it's working great in 2019!
