I don't use the Queue Manager on my Macs, so I won't be of any help with that.

My experience has been good with Catalina in general and what little I've used Poser under Catalina has worked as normal (so far.)

If folks are having Catalina issues like sschneew is experiencing, it would be best not to do the Catalina update. I normally don't jump in right away on a new MacOS release, but my MacBook is not my primary rendering machine, so I decided to give it a go. I'm not seeing the problems that sschneew is experiencing on my set up. My MacBook unlocks perfectly with my Apple Watch and I've not experienced any difficulties with iCloud services so far. Anyway, it would be good practice to wait for the first point release of Catalina before moving your Mac onto that OS. Perhaps Apple will fix the various bugs that always pop up with any of their releases.

I hope it all gets sorted out soon and apologies again for not being a Queue Manager kind of guy.
