  • New Mac and iOS App Pair Let You Unlock Your Mac By Knocking on Your iOS Device


    For those that dread having to type in their password on their Mac to unlock their machine each time it locks up, there’s an app for that!

    A new application pair for Mac OS X and iOS will allow the user to knock on their iOS device to unlock their Mac whenever it’s locked and the two devices are in close proximity. The application is called Knock, and it uses Bluetooth 4.0 technology to let the Mac know that you’re authorizing the Mac to unlock.

    Setting up the application pair is pretty simple. You will need to download the iOS application ($3.99 – App Store link) and download the Mac application (FREE – direct link) and install them on their proper devices. Once you're done, enable Bluetooth on both devices and follow the on-screen instructions on your Mac when you launch Knock. You will have to give Knock your administrator password on your Mac so that when you knock, it can automate the process of unlocking your Mac.

    After you've set everything up, and Bluetooth is enabled, you will find a new icon in your Mac's Menu Bar, as shown below:



    You will be able to invoke locking your Mac, quit the application, or unlink your iOS device that you have paired to your Mac.

    From the iOS device that you're using, whenever you're in range of your Mac, and the Knock application sees that you are, you will get a banner notification or a lock screen notification, as shown in the first image of this writing, telling you that you can knock twice on your iOS device to unlock your Mac.

    Notably, it doesn’t matter if your iOS device is unlocked or not, as long as the Knock application is running in the background. Knock uses a very low power draw through the use of Bluetooth 4.0, so the developers note that you won’t notice any battery drain no matter how much you use it.

    Knock can only be used on the following iOS 7 devices:

    • iPhone 4S or later
    • iPad (3rd generation) or later
    • iPad Mini and iPad Mini with Retina Display
    • iPad Air
    • iPod touch 5G

    Knock can be used to unlock the following kinds of Macs:

    • MacBook Air – 2011 or later
    • MacBook Pro – 2012 or later
    • iMac – 2013 or later
    • Mac Mini – 2011 or later

    You can watch the Knock demonstration video below:

    It seems to be a really cool way to unlock your Mac, but for the amount of times you might actually use it throughout the day, the asking price might be a little steep. Will you be trying Knock out on your Mac?

      I think I'll continue using airlock that does the same thing but doesn't require me to touch the phone also

      Tried it, fun a few tumes, but annoying that you need to wake up the screen first by typing a key on your keyboard or mouse first. Also you need to knock on your phone realitively hard, would make me feel umcomfortable doing that all the time.

      Any idea where I could download most recent airlock? I can only find v. 1.5b1 and it doesn't work with 10.8.

      It works alright... thing is, if you close the app I also had to disable and reenable bluetooth. I think it's nice, but likely more of a gimmick.
