OS X sierra can not unlock MacBook with iwatch
I did the upgrade to both sierra and iOS3 (iwatch - series 2) successfully. I have a new MacBook pro. I've done the 2 step authorization on my MacBook and iPhone 7, and I've also turned on the security setting of letting my iwatch unlock the laptop. When I go to unlock the computer the display reads 'unlocking with iwatch..." then it stops spinning after awhile and I have to input the password in as usual because the watch doesn't do the job.
MacBook Pro with Retina display, macOS Sierra (10.12)
