If you’re like me and your iPhone is jailbroken, you might have gone crazy realizing that iMessage and Messages on the Mac no longer work together. But this is not true as I just found out. It turns out that after completing a jailbreak, the iPhone just needs to completely re-register with Apple again for it to work seamlessly with Messages on the Mac.
How do you do this? Easy, you just go to Settings > Messages and then turn the iMessage button off and then on again. Wait a few moments and your phone will say that it’s in sync with your Apple ID and then just make sure your Send & Receive addresses are all correct. Once this is done, you will get a message on your Mac saying the same thing. Whew! I thought this was a bug, but I’m glad it’s not!
