dunno if this has been mentioned already. i've got iOS 8.1 beta 1 running on my iPhone 4s, and OS X Yosemite GM Candidate 1.0 on my late 2013 rMBP. Whenever I go into my Messages settings on my Phone and go to the SMS Forward thing, swipe the green button for my Mac to on, it asks for the passcode from the Mac. But I can't see the passcode on the Mac? How did people do it? Or troubleshooting help please? Cheers.
