I recently got an Apple Watch series 3. I also have a MacBook Pro 2014 running High Sierra. I am having issues unlocking the MacBook with my watch many times. I know I have setup everything correctly because it does work about 50% of the time. Is there a distance the watch has to be within the laptop? I am wearing the watch and usually my hands are on the keyboard so the watch is not far. Does the watch screen need to be on? Even when it works, it would've been faster if I typed the password manually. Anyone having similar issues?
