Messages Not (never) Delivered from my Mac
For months I've been unable to send Messages from my Mac. Every now and then I visit dozens of threads, search on YouTube, find a bunch of "tutorials", follow all suggestions and instructions, and still I'm unable to send messages from my Mac. Instructions go from unbelievable suggestion to make sure I have internet connection to disable/unable Cloud, etc. This problem is so recurring that people create entire blog posts on their blogs and sites.
So my question is: why is this so difficult for Apple to explain how to fix it for good, while WhatsApp works just fine?
