+1 on this question! Was getting ready to upgrade to 10.13 now that it has been released, BUT I rely on EyeTV-3 to control my EyeTV-HD (I'm a long-time US user), and there's no other hardware/software combo available in the US that I'm aware of that's designed for the Mac. So, no MacOS 10.13, until EyeTV-3 works reliably!
Any updates on this?
