CONCLUSION (of my rant fest): I had a good email conversation with Surtees Studio's tech support. They apologize for the [extraordinary] process required for the upgrade. They are going to look into finding a streamlined automation process. There are a few elements involved. (1) The new version uses a new security certificate, requiring users to set up security settings all over again. (2) Changes in macOS Sonoma in particular have made look like the old settings remain, when they don't. That's Apple's fault. Apple also has failed to provide an automated method of working around that nonsense. Therefore, a forced RESET is typically required using the CLI (Character Line Interface). Shameful Apple. (3) Amidst this mess, Surtee's Studio put out a sloppy workaround process, and GUI, and added CLI reset instruction page. - - FUTURE: Expect the Dev to clean up the process. I would also hope Apple sorts out their own, sadly perennial macOS blundering. 🙄😤
