iMessage stopped syncing between MacBook Air and iPhone 5
Hello,
Until the weekend my iMessages synced between iphone and MacBook Air, but from Monday I have been sending and receiving iMessgaes from my phone which never arrive at the MacBook. I didn't get the iOS upgrade till yesterday so it's not that, and haven't knowingly made any other changes over the weekend. I've checked both setups and both are syncing using my phone number plus 3 email addresses.
Can anyone tell me how to fix it please?
MacBook Air, OS X Mountain Lion (10.8.2), Numbers 09 v2.2
