My iMac is No Longer Answering My iPhone's Calls
I don't know what happened, but for some reason my iMac (27"5K Retina late 2015 w/ Mac OS 10.13.3) is no longer answering my iPhone's (iPhone SE w/ iOS 11.2.6). I have everything set up according to this Apple page: Make and receive phone calls in FaceTime on Mac - Apple Support
This is really a PIA.
Any hints or helpful suggestions?
iMac with Retina 5K display, macOS High Sierra (10.13.3)
