To Version 2.0 of the iMessage guide ...
My original guide started life as just a few paragraphs on getting iChat running on OS X Lion, back then things were simple and easy. However, as Apple's messaging app and its on-line eco-system has matured over the years, getting this unique messaging system to work correctly on non-Apple hardware has become more and more complex and i've done my best to keep the guide up to date.
In Jan 2015 the guide became un-manageable, news, tips, notes, fixes and procedures were all combined in to one massive post .... it wasn't intentional, I just never imagined that it would become such a popular subject and grow so big .... with well over 1 million views the time was right to put some some structure to it all.
I hope you like the improvements .... by breaking the guide up into different chapters and re-ordering some of the procedures, new-comers to the guide should be able to find the information they need quicker. In-addition to the new index i've added a lot of inter-guide links between chapters allowing for quick navigation around the guide without opening a new tab/page every-time.
Note: I'll be working on improving, re-wording and condensing all sections of the guide over the next few weeks to ensure that it's up-to-date with the current iMessage activation methods and information ... the 'Last Modified' date in the Index list will identify when a chapter has been updated.

This guide is all my own work and is the result many hours of experimentation, research and writing, however I would not have been able to join all the dots together and create the guide without the help and support of the OS X Hackingtosh community on this and other forums ... I have tried to list credit to those that have contributed directly to the guide at appropriate points in the text but there are far too many names to list and thank individually so my thanks goes out to everyone in the OS X community who helped or had input to the guides content.
I hope this guide helps you fix your iMessage problems and more importantly that you gain a better understanding of how Apple's on-line eco and messaging systems work and the importance of configuring OS X and it's System ID's Correctly.
