I have a tip but can't seem to find where to post it!
Hi Guys, long, long, looooooong time listener here from the UK! Here's the scenario:
1. Setup: Late 2013 MBP running Mojave (latest 10.14.1 as of todays date). iPhone XR, latest iOS (12.1 as of todays date). Both on same wifi network & signed in on same apple ID.
2.Problem: No matter what I tried I could not make or receive calls using my mac, followed the guides online, still nothing. I discovered that the "Calls on other devices" option in ipHone>settings>phone was missing. Googled around, no joy. Had a web chat with support. Tried all the usual stuff, nothing. Stumped.
3.Solution: I ended up typing the exact wording that the iPhone prompt says when the option becomes available but will still not work into google and found that there is a single, tiny teeny setting in Facetime settings that needs to be on. iPhone>settings>facetime and tap "Use Apple ID for FaceTime". That's it! An hour of searching. Tapped that toggle and all fell into place.
I thought I'd post this as it was driving me insane and it might help someone else! Hope it appears in the show! Thanks all!
