I downgraded back to Java 8 251 and this solved the problem. Definitely related to the 261 update. I know others have said they are running it on Catalina, but something different on my end, obviously. Thanks to everyone who tried to help.

This looks ominous.

Just tried that as well, and still the same issue. I also changed the memory (added -Xmx9000M to runtime parameters in the JVM console. Still no luck!

Thanks, yes, I just did that, have the same issue.

Yes. But days ago. Admin console has been working fine, and does still on another Mac. Just this Mac, which also was working, stopped. Seems related to the Java update, since that is the only difference between the Macs.

And ISY 5.016C

I just updated to Java V8.261 and the ISY Launcher will not launch. 1. Downloaded V8.261 for Java released on 7/14 and installed. Install went fine. 2. Rebooted the Mac 3. Cleared Java Cache in Settings as instructed 4. Downloaded the launcher at https://isy.universal-devices.com/start.jnlp 5. Every time it starts, it appears in the dock, nothing appears on the screen, and then it just shuts down. Mac OS Catalina 10.15 Any ideas/help appreciated.

thank you.

Awesome, thank you everyone, much appreciated on the Zip/install issue.

I am trying to upgrade to 5016, but what file to I select? On the mac, it downloaded a directory called Insteon_5, and I can't select the directory, when I do, it then drills down and asks me to choose from subdirectories Web, Def and Code. ??
