Sadly, that is the official fate although folks are still pursuing work-arounds including a more updated cert that was posted Dec. 2021 here: https://www.tivocommunity.com/threads/new-program-for-1-step-ttg-downloads-decryption-encoding-kmttg.387725/post-12461597 (Start with the file in this post and read some of the subsequent discussion.)

While I feel a bit devastated to learn that kmttg development has been "abandonded" (ended), I just wanted to thank @moyekj for all of the effort that went into creating and maintaining this software for us power Tivo users over the past several years. It was brillant little solution for Tivo management (far superior to the old desktop software from Tivo) and I'm hopeful that while it may be unlikely it will see any new features, someone will come along and be able to keep it functioning by updating...

Tony, this may sound like a dumb question but have you tried just double-clicking kmttg in the Finder (without trying to futz with the Java setup further)? If you installed Version 8 Update 201, it updates the JRE in /Library/Internet Plug-Ins. While this version is no longer used by Safari 12, it is still used by macOS' Jar Launcher, the core component of the OS that allows Java .jar files (like kmttg) to be double-clickable (launched) in the Finder. Note this won't help you with trying to start...

Tony, I don't want to go too off topic here as this is the feedback thread for this Wiki page. I suggest posting general question to the Discussions forum in the future but I'll reply to you directly as I know the answer. (It is not Java related)

The Java "client" or JRE versioning has become even more of a nightmare than ever to sort out for the layman. On macOS in particular, Apple Safari 12 finally dropped support for the Java "plug-in" that had been included with the OS (which up until 10.14 "Mojave" was linked to the Java 8.x series JRE installed in "/Library/Internet Plugins"). If the user was unfortunate enough to have gotten as far as installing JRE 10 from Oracle in the past year or so (thinking they were keeping things "up to date"),...

I wrote up an updated version of the first step of these instructions to account for changes to Oracle Java and installations on macOS. I didn't want to fully modify the Wiki without permission so I am adding them here. 1. INSTALL JAVA 8 IF NEEDED Kmttg is written in Java and the latest versions require Oracle Java version 8 (1.8.0_xx) where xx is any current version above 40 (i.e. 1.8.0_201). Java 11 is not currently supported. To determine if you have an appropriate Java 8 JRE (Java Runtime Environment)...
