Proximity? Yes. Mac, iPhone, and iPad know when they’re near each other, so the perfect proximity example is that you can take or place phone calls from the Mac instead of digging into your pocket or bag to answer the iPhone when it rings. Here’s a little proximity security utility that locks your Mac when you step away, and it’s free.
Leave And Lock It
Apple’s Handoff feature on Mac, iPhone, and iPad is merely representative of what’s coming as your devices become more aware of you, what you’re doing, and where you are. Here’s a simple and free a way to lock up your Mac when you walk away. All you need is an iPhone and handyLock, a free utility that does the deed automatically. Install handyLock on your Mac and Pair it up with Bluetooth on your iPhone (also works with Android devices, iPad, et al).
Use the sliders to control the lock distance from Closer to Farther away, and the reaction speed from Faster to Slower.
Otherwise, that’s it. When you and your iPhone get up and move away from the Mac, handyLock senses you’ve moved and locks up the Mac until you return.
How sweet is that?
The only difficult aspects of using handyLock is the Bluetooth pairing, usually easy but it can be problematic, especially on older Macs. Oh, and remembering to keep your iPhone nearby. Otherwise, if you leave the vicinity of the Mac but leave your iPhone behind, then both phone and Mac become attractive prey for thieves.
That means you’ll need to get into the habit of walking away from your Mac with your iPhone in hand. In setting up handyLock I had to play around with the Lock Distance slider bar, and the Reaction Speed slider bar to get it just right, but it works well once it’s up and running.
Not bad for free, right? And even more flexible than what Apple builds in to macOS Sierra.
Wait. There’s more.
What if you don’t have an iPhone? handyLock still works with newer Android smartphones, iPads, iPod touch, and even newer BlackBerry models. All you need is Bluetooth. Get it paired and you’re good to go.
