I have downloaded all the new betas today and was able to succesfully setup unlock with Apple Watch on my Macbook (Early 2015) Model but on my MBP (Mid 2015) when I setup Auto-Unlock I get a pairing request from my watch on my MBP. It's asking for a passcode displayed on the watch (which is not appearing). This did not happen when setting it up on my Macbook. After a 15 seconds or so the prompt for the passcode goes away and the check mark fills in. But when I attempt to unlock my MBP I get the spinning wheel and then it prompts for the password. I have not been able to sucessfully Auto-Unlock on my MBP. Macbook is working great. Any ideas? Would rather not chalk it up to a beta glitch...
