Hi Terry,
Boy, it does seem like it’s the instrument that’s the common element there. Since it does not work in i1Profiler, and it is an X-Rite instrument, your next step would probably be to contact Tech Support at X-Rite and have them walk you through determining if the device is bad. Then they can issue a return authorization. 888-749-9944
The Console.app is in the Utilities folder. When it is running, it gives a sort of step-by-step readout of everything that’s going on in the computer. People smarter than me can sometimes make sense of all that gibberish. All I know is that it reports a lot of scary things like “device not found” and “failed to restore settings” for a lot of software that is actually operating normally.
