When I first set-up my iPhone 5, I was instantly getting iMessages on my Mac, but it has since stopped. I have tested numerous settings and can not get it up and running. Here are the settings: On Phone: Settings -> Messages -> iMessage is set to On -> Send & Receive -> My Apple ID is correct, "email@example.com" and I have my phone number, @gmail.com and @icloud all checked to "You can be reached by iMessage at". Should I select my @gmail or phone number to "Start new conversations from"? What difference does this make? On Mac: I have the most up to date version of software and all updates. File -> Accounts both iMessage & AIM are checked. Any other adjustments I need to make on my Mac?
