I've been running Indigo on a Mac mini for several years without problems. Currently I run OS 10.12.3 on m y Mac. I upgraded to Indigo 7 and now get error messages often that say the Indigo Server is currently not responding. The pop up window appears with the Start Local Server button and I click on that and all my settings appear correct. Usually it doesn't allow me to restart the server and clicking start server does nothing. I am not that techy so lot of this stuff is over my head but currently running dozens of Insteon devices in my house.
Please help...my lighting doesn't work in the house without Indigo running. Can I go back to Indigo 6? What should I check?
