I'm still using Eyetv 3 on iMac because it works and also because i'm not even confident that if I purchase a key for Eyetv4 i will be sent a code to use it. And like the previous poster said will that code only work once? Can I put it on my MBP also? The new owners should really read these forums and get more engaged.
M2 Pro mini, 14.1.1, 4.0.0 (8532), EyeTV HD, USA, woks fine for me. Whatever the previous version did as well, no problems. I am still pissed though about the guide DOA all these years. 😠
As of 31 Oct 2023, EyeTV 4 (8531) can be found here, along with several other versions going back to (8521):
At www.GeniaTech.eu under Support-->EyeTV 4 Software
I am running (8531) on an M2 Pro Mac Mini running MacOS 13.6.1 without issues. I use an (ATSC, not DVB-T/T2) EyeTV Hybrid USB stick.
