I've setup my apple watch to unlock my iMac however whenever I test this, it requires me to login with my password and tells me that "Wireless signal is too weak..."
I'm using a late 2013 27" iMac.
Processor: 3.2 GHz Intel Core i5
Memory 8GB 1600 MHz DDR3
Any suggestions to solve this would be appreciated. Thanks.
iMac, macOS Sierra (10.12)
This has been driving me nuts! I've got a late 2014 iMac retina + iphone 7 + 1st gen watch with watchOS3.. so all the toys.
My wifi seems stable RSSI -55 dBm / Noise -84 dBm
auto-unlock works maybe 25% of the time or else just dumps me back at the password prompt. I've tried selectively switching off both 2.4 and 5ghz wifi (both on same SSID as normally recommended), switching off all advanced ASUS router settings. I also switched off wifi on the iphone and still got same level of success.
So its either a Bluetooth issue between watch and imac or maybe a wifi compability issue.
A couple of other points..
Twice I've seen my apple watch appear in the macos bluetooth device list... most of the time its not there - is this an issue.. do others ALWAYS see their watch listed?
I've can see my watch in the DHCP client list on my router... but am not able to ping it.
I see this from time to time on two different Macbook pros. One is a new 2016 and one is a 2015 model. Unlocking with my watch usually works but at least once a day, sometimes more, I see this same error.
Are you using the Applewatch together with an iPhone 5 later?
The unlock feature requires any 2013 and later Mac model running the new macOS Sierra using an Apple Watch running watchOS 3 with an iPhone 5 or later.
I'm using a the Apple watch with iPhone 6s Plus 😕
I am assumimg your watch is running watchOS 3?
Yes sorry. Apple watch is running OS 3
I just got this for the first time today. It happened 3x and then I opened my phone to run a speed test and confirm my wireless stability.
Speedtest went fine and the next time I tried to unlock via Watch it worked. I'll post again with any more details, but at this point, my guess is that the phone or watch somehow didn't have a solid wireless connection.
There is still some mystery in how this unlock feature works, but I know from Apple's tech review that they are, literally, timing wireless connections from the Mac to you Watch, dividing by light speed and computing that you are, in fact, next to your Mac and not having your BLE connection hijacked and repeated.
Given all that AppleAchemy™, some ****'s gonna go wrong sometimes :-)
Hope this helps
Seeing the same problem about once a day, Apple watch v1 is about 36" from MacBook Pro (Retina, 15-inch, Mid 2015). Have extremely strong wifi connection. Seems really odd.
And you also have an iPhone turned on while attempting this?
The discussion above already covers the basics... esp this reply:
Re: Wireless connection is too weak to unlock with apple watch
You may need to perform a few resets if the devices are all there
but just not working as expected. See the 'help viewer' for links
to support articles, or a search for more untried information.
Good luck! 🙂
I've tried everything including all suggestions from apple support. I've also had apple wifi engineering collect diagnostic logs. From what I can tell there are lots of users suffering from unreliable apple watch auto-unlocking and many (like myself) have probably just given up and switched it off.
Its a good idea and if one-day they can make it work, great.
Has anyone tried a PRAM reset and SMC Reset? Since doing this for an unrelated problem, it seemed to fix the issue for me.
It looks like macos 10.12.1 fixes my auto-unlock problem! Just done 10 unlocks in a row without a problem.
Happy days.
I see the Wireless connection is too weak to unlock with apple watch occasionally. Happened today at the office. I canceled the login and tried again and it immediately worked.
