FaceTime just doesn’t work!

For over a year, FaceTime on my late 2012 iMac won’t connect or receive a video call. I’ve spent hours in forums and trying every method I can find – permissions repair, a new user account, automating date and time preferences, deleting the app’s preferences file, and Safe Boot.

Messages has had problems for about the same time, logging me out almost every time I close it. My iMac and iPads that I want to receive calls have the latest operating systems – I live in hope that the next update will be the one that fixes this! Peter Walters Can your iPad make FaceTime calls? If that can’t be done either, then this must be a problem with your network itself, not your Mac. iMessage needs network ports 80, 443 and 5223 to be open. FaceTime needs those, plus all the ports in the ranges 3478-3497, 16384- 16387 and 16393-16402. If any of these are blocked by your router’s firewall, you won’t be able to make or receive calls. Open the router’s configuration page in Safari – you can find out what IP address to use by opening Network preferences and clicking Advanced > TCP/IP. Use this page to turn on port forwarding for these port numbers and see if that helps.
