    I have a 2017 iMac and my new series 3 Apple Watch will not unlock it. The computer says I need to update my iMac, but the iMac is all updated.
    I do have a Apple Watch series 0 and it unlocks the iMac.
    I wouldn't think I would have to have the new High Sierra for the new watch to work.
    Anyone else have this problem.

    I think we have to wait until Monday when High Sierra comes out for whatever reason. It seems nobody with an Series 3 is able to do this, but it seems to work fine with people running the HS beta

    WatchOS 4 on a Series 2 and HS beta have been working fine for me.

    Here are the requirements from Apple:

    If you have a Mac (mid-2013 or later) with macOS Sierra or later, your Apple Watch can instantly unlock your Mac when it wakes from sleep. You need to be signed in to iCloud using the same Apple ID on both your Mac and Apple Watch.

    Tip: To find out how old your Mac is, click the Apple menu in the top-left corner of your computer screen, then click About This Mac. The year your Mac was made is listed next to the model—for example, “MacBook Pro (Retina, 13-inch, Mid 2014).”

    Turn on Auto Unlock.
    On your Mac, choose Apple menu > System Preferences, click Security & Privacy, then click General. Select the “Allow your Apple Watch to unlock your Mac” checkbox. If you don’t have two-factor authentication turned on for your Apple ID, follow the onscreen instructions, then try selecting the checkbox again.

    For more information about two-factor authentication, see the Apple Support article Two-factor authentication for Apple ID.

    Your Mac must also have Wi-Fi and Bluetooth turned on.

    Unlock your Mac. While wearing your watch, just wake up your Mac—no need to type in your password.

    Tip: Make sure your Apple Watch is on your wrist and unlocked.

    There are a few reddit forums about this, apparently we need to wait for Monday's update.

    It is not working for me either. I have a 2015 macbook pro. I have followed all the steps, I have restarted all the devices, and still it does not work

    I had to log out of iCloud on my Mac and then back in again for it to work...

    MBP Late '13 running High Sierra + AW3 is also not working for me. It keeps spinning "activating" and then fails. Worked fine with my AW S0 in the past though on Sierra.

    Sometimes it works and sometimes it does not - I got it working after signing out and back in to icloud on all the devices - and it worked awhile this morning but when I came after a couple of hours - it did not work again

    Does someone else have an account on the computer? I found that if someone else signs on to the iMac, I can’t get the unlock functionality working until I reset both the watch and iMac, then toggle off and on the option to activate the unlocking. It doesn’t play nice with multiple users.

    It is working for me, but now when I use my computer while my watch is on charge I have to type in the password--I was hoping it would allow me to use TouchID. I might turn off the unlocking via watch, since most of my computer use is at night and it's annoying not to be able to use TouchID on my MBP.
