There is a clear discrepancy between the macOS upgrade page you reference and the Unlock your Mac with Apple Watch KB article (https://support.apple.com/kb/PH25156?viewlocale=en_US&locale=en_US) -- the former suggests that all 2013 Retina MBP support the Unlock your Mac with Apple Watch feature while the KB article says only mid-2013 Retina MBPs are supported.

It is clear that the KB article is accurate based on the results with my early 2013 15" Retina MBP.

I've ordered the Broadcom Bt 4.0 Wireless 802.11ac Wifi Card Module (Bcm94360cs Bcm94360csax Bcm4360 Bluetooth) for Apple Laptop A1398 A1502 653-0029 to see if this will enable the feature .

Based on the Amazon reviews and questions/answers this appears to be a promising step. It is scheduled to be delivered on Thursday. I will report my results here.

The card can be viewed/ordered here: https://www.amazon.com/gp/product/B00PDN4H9E/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1)

Please let us know if you get it working :) I have an early 2013 15" MBP as well.

I had to Unpair my Watch from my iPhone and then Pair it back again. Otherwise I could not get it to show up as a trusted device after switching to two-factor authentication no matter what else I tried. It was a pain, but I finally have it working now.

I believe this is the key. If you had 2 step on with an AW already paired to your phone and then changed over to 2 factor, I think it breaks something between the two and you have to un pair and repair it to make the new 2 factor connection. Otherwise, nada.

lol, does anyone actually believe it's in reference to the actual kool-aid drink?
Maybe not, but it's ironic that people blindly follow others in using the wrong brand when trying to call someone else out for being blind followers (usually because that person doesn't agree with them).
 
After previously having 2-step verification on, changing it to 2-factor verification only worked to allow the Apple Watch unlock to happen once I'd unpaired and re-paired my Apple Watch to my iPhone again. Prior to that I'd signed out of iCloud on the MacBook, which didn't do it. So anyone stuck the unpair to re-pair did the trick.
 
I have Continuity and Handoff on my Late-2012 rMBP, so I'm anxious to see if this works for me.
Got it working on my 'hacked' 2012 rMBP (I have a 2013 rMBP Airport Wireless AC card installed)

Well this sucks, both of my Macs don't support it. Argh. Fully into the Mac ecosystem - Mac, MacBook, iPhone, Apple Watch, Apple TV, and CarPlay... and no fun for me because my Mac is a few months too old. Very disappointing.
 
hi @magbarn ! Which Card do you use on MBP 2012 now?
Thanks
Look up BCM94360CSAX at amazon or your favorite auction site. Read ifixit guides, be gentle with the little antenna wires, and get good quality screwdrivers

EDIT: OOPS! I didn't catch you had a regular MBP and not a rMBP. Sorry, the MBP use a totally different form factor. Some enterprising individuals have tried to make an adapter so you can sue rMBP wireless cards in a regular MBP, but I don't think they were successful. Sorry!

I tried to set this up, I had it working prior to the last GM version of Sierra, now I can't set it up. The option to unlock with your apple watch magically disappeared from settings, too!

Any ideas?

Thanks, I must try. I have a late 2012 MBP and would love to have this feature if the card will work for a non-rMBP. There must be something on the BLE chip itself that will allow it to listen while the computer is sleeping ,I can't think of any other reason a BLE MBP would not work otherwise.

[doublepost=1474562528][/doublepost]Nevermind, the connector is completely different, dang.

This was my most anticipated feature of macOS Sierra, and just found out it'll only work on 2013 or newer macs!?! both of mine are from late 2012... FFS...
 
Using my MBr on macOS Sierra, iPhone 7 on 10.0, Apple Watch on watchOS 3.0, and iPad Pro 9.7" on iOS 10.0.

I have two factor verification set up.

I do not even see the "Unlock with Apple Watch" option in the general tab of the Security & Privacy section of system preferences.

Anyone have any idea why?

My fault! i have a rMBP late 2012! ;) Amazon order done! I will try!
 
It works as mentioned on my 12" MacBook.

However I disabled the features, as it required me to have a passcode on watch and I dislike having a passcode on watch, as its a hindrance to quick use.

Hopefully the future updates, will give an option to have it on watch without passccode.

It's not a big hindrance, you only have to enter the passcode once when you first put your watch on.
 
OOPS! please dis

why don't you use your iPhone to unlock your watch? Works for me. I almost never have to put in the passcode. Considering Apple's recent security mindset I highly doubt they'll give you that feature as they even require you to do 2 step verification just to enable the watch unlock.
