At first I thought this was similar to a bike lock so that your Mac can't get stolen. But that doesn't appear to be what this is. I don't see why simply "locking" your screen with something as simple as configuring a Hot Corner (all I do when I leave my Mac is swipe my trackpad to the bottom left) and it locks the screen. Logging in again isn't a problem no matter where it is. The fear is that if I'm in a coffee shop, my entire device will be stolen.
A friend brought up another scenario, where you have to get up fast. If the Hot Corner is not fast enough, you can always just close the lid.
On the other hand, a fob like that seems unreliable in comparison. Aside from "steal the fob" (which, arguably, is similar to "steal the Mac, get info from Mac"), what is the operating envelope? At what range will it shut it down? At what range will it reactivate? How reliable is it?
I hate to be that guy, but hasn't this idea been around for a while, but using the bluetooth on your phone? Aside from using Bluetooth 4 (LE), what would the advantages be to this?
I'd also caution against marketing this as a "Mac lock"... I at first thought it was going to be an alarm for the physical device, not the OS.
Yep, I used it before on Windows - the problem was that the Bluetooth range was too long :-).
But it works great without the need of yet another piece of hardware on you (that you need to charge I think?).
First, that the opening title about the coffee thing - I had to re-read that section twice to realize it wasn't referring to someone getting a refill in a coffee shop and wondering why the heck would they leave their precious Mac behind.
Second, I would strongly consider redoing photos that have woman's hand in them. As odd as it may sound, the nail polish color is annoying and distracting. It has this old lady feel to it. Also there's something altogether wrong with the second from the bottom photo, it is just ... gross.
Also, the fob seems to be just a tad too big. I can't help but to compare it to the Fitbit. That's the baseline for size and it's got the wireless proximity sync and an incredible battery life. It may not have crypto support, but there are few simple ways around it (e.g. preloading one-time pad during paring over a wire).
All in all though - very cool. I'd rather see one project like yours than a hundred of Jekyll JavaScript icons for MongoDB on Bootstrap or what have you :)
Looks great! I don't really suffer from the possibility of people snooping whilst I'm away, but it'd be a great convenience device.
I'm an iOS developer as well, but I haven't delved into OS X development. What makes the device compatible with newer MBP's but not older ones (i.e. my 2009 model)?
I did this with my phone using a wireless hotspot and some bash scripting. Basically you're paying 40 euros for closed source hardware that works only with Mac, when you could do it with some scripts and your smartphone ;)
you can already build such a system yourself quite trivially by getting an FTP account, mounting it locally with curlftpfs, and then using SVN or CVS on the mounted filesystem. From Windows or Mac, this FTP account could be accessed through built-in software
I think the time cost of implementing this would be more than 40 euro, unless I enjoyed the process of writing it -- and it's pretty safe to say that most products are marketed to people who wouldn't enjoy spending their time reimplementing them.
Why isn't it possible to just use your iPhone or any other Bluetooth (4.0 low energy) device, they should have a unique mac address and could be used for something like this.
But really, I'd prefer this to be an app on my phone instead of a keychain. I usually walk away from my computer with my phone but I'll leave my keys on my desk because they're more uncomfortable in my pocket.
Flashback to 2005 and the Security DR 90105 00 PC DEFENDER Wireless Screen Lock Data Protection. Hope Sesame put more effort into wireless security and the client software!
I thought this was going to an alternative to a physical lock, which seemed impossible, but on my way to click on the link it occurred to me you could setup the Mac so it sounded an alarm if moved, unless you unlocked it with your password. Which would be also be a cool idea. (Since I am at a cafe I guess my mind went more towards physical security.)
Aside from the other comments that the functionality could already be replicated with a mobile phone, it would be cool if the device could have some kind of screen effect as though the machine is powered off. (ie. the power pendants in the TV series Revolution)
This looks cool, but I would really hate to have to always have the device on me for this to work. I can just as easily hit Control+Shift+Eject to lock the screen when I get up.
To me, it's more of a convenience factor. You could walk away and have it lock automatically and come back to your computer and have it unlock automatically. The manual option is always there.
I have looked for a solution do doing this before but they haven't worked exactly the way I had expected.
If you have a laptop, just close the lid. By default (on a Mac) you have to log in again when you return.
If you have a desktop, what kind of environment are you going to be in where you need to guarantee the screen locks when you are away even momentarily?
Serious call centres are red hot on data protection, at least here in the UK. I can imagine these being useful there. That said, with 200+ of these little things in one building i can imagine the bluetooth range might get a tad busy!

Here's a photograph of fitbit next to Sesame. They're about the same size.
