Mac Security Alarm System 243

RogueAce writes "A program named iAlertU sounds a screeching siren when someone attempts to steal your Macbook. Thanks to the sudden motion drop sensors that Macs use to park the hard drive, iAlertU can detect when your Macbook is being picked up, moved or closed. Also, by using the handy remote that comes with the Macbook, you can turn the alarm on and off like you would a car, which the Macbook responds to by making the all too familiar chirping sound and a flash and flicker of the screen. The code behind it is from a guy named Christian Kleins."

      That's a bit of a simplistic view. If my car alarm goes off, I go check on it and make sure somebody hasn't broken a window or something. I've seen others around the complex do this, too.

    ...unlike a car. When someone tries to steal a car and a car alarm goes off, the car itself isn't going anywhere (although you may have a broken window or two.) Unfortunately, when someone tries to steal a Macbook and the iAlertU alarm goes off, I don't think the Macbook will fare too well as a result. Most likely it would be dropped out of sheer surprise, or dropped/thrown in the process of trying to escape the irate Mac owner and the local security guards.

    Still, I suppose even an inoperable Macbook with the hard drive intact is better than having all your corporate and personal data stolen.

      When you plug headphones into a Mac, the audio is rerouted away from the speakers in software, not hardware. This allows things like USB speakers to work, so when you plug headphones in, it mutes the USB speakers. So, in theory, this software should be able to override that and always use the built-in speakers even if headphones are plugged in. (I doubt the current feature has this feature, and it probably wouldn't be easy to implement, but it should be possible.)
      • The system already allows for separate outputs for alerts and normal sound out. From the System Preferences you can select the built in speakers for all alerts while still using external speakers/headphones for iTunes. And this setting does not change even if someone were to plug in a headphone jack. So, chances are that this would be simple to implement using the built in system libraries for audio.

    That's a nice novel use for an otherwise unrelated technology. I'm sure the SMS wasn't intended for security, but it works well for it.

    As for being off... I wonder, does anything run while the laptop is asleep? My powerbook has probably spent less than 5 minutes turned off in the last four months. Most users close the lid and sleep it. (my powerbook draws the same 2 watts when it's asleep as when it's off, so why bother turning it off?)

    A firmware hack might enable the alarm to wake up the book if it's moved. I assume the PMU/SMU is controlled by flashable firmware. Also, the SMS is in the older powerbooks also - this article only mentions the macbook pros, I wonder if it works in the older models also?

    This is great news. There's a coffee shop in my town with a friendly college crowd and free Wi-Fi networking.

    My problem arises when I take my old Powerbook in there and realize I need to use the restroom. The crowd is pretty honest and I'm pretty quick in the facilities, but I really hate packing up my whole setup and taking it into the stall with me. This might allow me that feeling of security to leave my old Powerbook out while I take care of business.

    While there's still some risk involved, it sounds like this will be just the thing to make me:

    • Carefree and proud to be a Mac owner.
    • Careless about risks and have my computer stolen.
    • Embarassed when someone bumps my table and I'm caught with my pants down.

    I'd probably risk this with my old model Powerbook, but I don't think I'd do so if I upgraded to a new MacBook Pro.

    I work in an office where stolen property is nearly a common occurance (a stranger came in and simply sauntered off with a petty cash box the day I started working there). To guard against this, I keep my Mac Decoy Pro in my desk.

    What's a Mac Decoy Pro, you ask? It's an extra nonworking Macbook Pro. Looks just like the real functional thing, just sitting there waiting to be taken.

    Where did I get it? Well, when I heard that Powerbooks were going to use Intel processors, I bought a Macbook Pro with the express intention of swapping out the hard drive, memory and processor: the first two I did with nary more than a dented/warped casing. The latter... well, my screwdriver slipped and broke several components off the main board. I tried the purchase just the notebook mainboard from Apple, but essentially, they told me to go screw myself*. So with a heavy heart and a sigh of resignation, I did what any self respecting geek would do: I played poker for an hour until I had enough to buy another Macbook Pro. I've reassembled the broken one, which I leave out in the open in my cubicle when I go home at night. If it gets stolen, then that's my alarm indicator that it's time to leave the company.

    In the last two years I worked for a company that had a handful of laptops with custom GPS hardware inside the cases. No software controls, just hardware added to the inside of the case set to transmit under certain circumstances. They also had software to report back to a central server whenever they were connected to the internet.
    Laptop was stolen, theft was noticed, word went out. Laptop booted up, transmitter in laptop transmited. Laptop booted from CD without going into the case and turning the transmitter off, laptop began transmitting continously. Windows format and install takes a while, so the signal was transmitted for more than an hour. Some wandering around with recievers until company security was sure they had the right apartment. Police called and informed of the situation and that company security is going to get the laptop back, now, would the police like to meet them there?
    End result was laptop recovered in less than 12 hours, and thief in jail for felony theft. The laptop was gone longer as evidence than it was gone with the thief.
    It is expensive, it is not perfect, and I have no idea how you would get it into a case with as little freespace as a
    Mac laptop, but it can work very well.
    I would be more specific but I signed one of those NDA's that some companies love so much.
    The main starting problems would be the usual, cost, how to fit it in the case and maybe power consumption. Also, a big hurdle might be getting the police to declare a GPS signal probable cause to go into where ever the laptop is. Especially if the signal is not currrently transmitting. My previous employers solved that last one by sending there own people and then reporting the whole mess to the police, but most of us individuals don't have those resources. (Maybe that is a good thing, should /. readers be trusted with our own armed security? I know I shouldn't be. :) )
