@Techman oh, yes I do have a Polisy but it's just running some Node Servers like Open Weather, Push, Ping and MyQ

 

Yes, I followed the update procedures. I only have Insteon devices and the Polisy so no Z-Wave to fiddle with

One other thing you can try doing is deleting the ISY temporary files. First close the admin console. They're located in the following directory:

C:\(your user name)\AppData\Local\Temp

You should see 5 files starting with UDI.  Deleting them will not affect your configuration or programs, etc. They will be recreated next time you run the admin console

Where is that data stored on a Mac? I didn't see it in ~/Libracy/Caches

Sorry, I have no idea. Can you do a file search for udi_tree.state which is one of the files
