I know not supported.
Thought I'd post my logs to see if anyone at Logos would like to take a look in the hope of making it work one day. Just trying to help. If not needed then feel free to ignore this post.

Oh and by the way, I start up Logos and then it hangs on syncing docs and will not go any further. I will get to use the web site more on this machine. Yippee!
Kevin, I don't work for FL. But I had the same "hanging" on start issue when I first upgraded to Catalina. I deleted all my Logos caches in the OS library, ran cron scripts... and it started working for me. I am not saying this will fix yours. I am just sharing my experience. I am running macOS 10.15 Beta (19A501i) and Logos Bible Software 8.6 (8.6.0.0052). Hope it gets working for you. I posted this in both places.

Not sure how to run chron scripts so I'm just going back to Mohave.
