I believe the iMessage issues have been resolved now.

Hackintoshes are getting better, but Marco is fundamentally right. Any OS update could break your system, which means you need to wait before installing an update, which opens you up to security and/or professional risks (for example, if it takes a couple of months for the newest MacOS to be made suitable for a hackintosh, that's a couple of months where you cannot update your iOS apps with the latest features, since XCode versions also tend to be tied to OS versions).
