Hi John,
I am also a 32 bit wanderer. I have macOS 14 on lots of Macs and am pushing back the disruptive 64 bit Catalina move. One of my roadblocks is EyeTV on my Mac Mini central stage TV centre!
I wish the 64 bit EyetTV was at least as good as the 32 bit base. I realise it's a very coding hard transition but it's so close and they've done a lot of work and yet it needs some polishing
As a macOS dev, I wish I could help.
Cheers
Gerard from Australia
