Indigo Domotics

I have just upgraded to 7.1.1 from an earl;ier version of 7, running on Sierra. When Indigo starts up it tries to start the Z-Wave interface but stops it. Restarting the Mac did not help. This is in the log:

31 Dec 2017, 13:11:18
Reloading interface "Z-Wave 2.0.111"

Stopped interface "Z-Wave 2.0.111"

The Admin permissions on the plugin.log file and the indigoplugin.zwave folder were both Read Only. After a couple of attempts I reset them to Read and Write and Z-Wave started working again.

Keep an eye out for other permission problems (ex: when Indigo is trying to save its database file, create a new event log file, etc). When this has happened in the past it is because another installer (not Indigo) had messed up the permissions on the entire Application Support folder.
