A number of posts claim that Apple is banning Macs from being able to make iMessage posts at all.
However, not all is rosy for users, if the Beeper subreddit is to be believed. The logic worked, with the genuine registration data sourced from the user's own hardware, or a Mac they had access to, allowing access. In December, one of the last fixes for access offered by Beeper was a method of using a real Mac to connect to iMessage, and use that registration with Beeper Cloud and Beeper mini. Following a cat-and-mouse race between Beeper and Apple to get around Apple's security and allow Android device users to post to the iMessage network, it seems that some are finding out that they've got bigger problems with their own overall access to iMessage.
