Mac book pro late 2016 does not unlock with Apple Watch
Hello to all
I just purchased an Apple Watch Series 3, I'm trying to unlock a MacBook Pro last 2016, but when I go into system / security preferences and let me "allow Apple Watch to unlock the Mac" I do not find the Apple Watch .
I have both the Iphone and Mac with Wifi and Bluetooth turned on, and 2 factor authentication for the iCloud account,
but the problem persists
Someone to any help?
