Although I cannot say for sure, if your system can support 10.9, I’m pretty sure you’ll be good to go hardware-wise I got this working on a “Early 2008 Mac Pro” with 2×2.8Ghz Quad-Core Xeon processors.

10.9 is free and works great, so you really don’t have a reason to not upgrade anyway)
KNOCK FOR MAC MAC OS X
Mac OS X 10.9 or later (I think this may work on 10.8.x, but I have no idea.Before I get into it, here are some prerequisites that I think you need to fulfill for this to work: The good news is getting this working wasn’t very hard. I’m happy to report, I got it working like a charm (care of a minor additional purchase). I tried out Knock on my supported 2012 Mac Book Pro, and after seeing it work great, I was determined to get it working on my Mac Pro.
KNOCK FOR MAC PRO
Since Knock utilizes BTLE (BlueTooth Low Energy) 4.0, my 2008 Mac Pro didn’t have the goods built-in. Then I got bummed out when I realized I didn’t have a supported Mac.

I’m a huge fan of credential-less / multi-factor authentication, and this product was the first one in quite some time that got me really excited (I think the initial “magic” of Dropbox was the last thing that wowed in the same way). It is such a smart way to handle an otherwise annoying task of having to unlock your computer every time it locks. The Mac app client is a free download, available here.When I saw Knock to Unlock for the first time, I got really excited. So, should you buy Knock? That’s up to you and how frequently you’re unlocking your Mac, but in our quick tests, the app works exactly as described.Ĭlick here to download Knock for $3.99 in the App Store. Schlossberg previously directed the design at ecommerce system at online clothing retailer Bonobos. Henderson created a secure mobile payments platform at Square and previously worked on OS X at Apple. Knock was created by William Henderson and Jon Schlossberg. The app uses Bluetooth’s built-in encryption and Knock’s proprietary 1024-bit RSA encryption to create a secure connection between your iPhone and Mac. If someone steals your iPhone, you can still login to your Mac with your password, then disable the Knock app. The app requires an iPhone 4S, iPhone 5, iPhone 5c or iPhone 5s and the following newer Macs shown below: That also worked for us and would probably save you from having to ‘knock’ your iPhone multiple times per day if that scares you. You can also unlock your Mac by just giving your iPhone a couple firm ‘shakes’, like you do with the app Bu.mp or even tapping your iPhone on its side on a surface. This we assume prevents ‘accidental’ unlocks. You do need to give your iPhone a firm couple knocks for it to unlock your Mac, which works pretty instantly. Knock works with any Mac that supports Bluetooth 4.0.īelow are images of the Mac and iPhone setup, which was pretty easy: Knock securely communicates with your Mac using Bluetooth Low Energy, a new technology that draws very little power.

Using Knock won’t drain your iPhone’s battery, even if you use it all day every day. You never have to open the app- just knock on your phone twice, even when it’s in your pocket, and you’re in. You keep your iPhone with you all the time. Faster and safer than typing a password, for iOS and Mac.
