Even though iOS users have been using it for four years, the “Slide to Unlock” gesture is still pretty cool. Most likely because they don’t have touch screens, Apple hasn’t yet brought the gesture to Macs, even with the addition of Multi-Touch trackpads to the whole family. Luckily, Mac App Store developer iDevelop Co. has come up with an app called Lock Screen 2 ($2/$5). In addition to adding a sliding lock mechanism to your Mac, it lets you choose a customized lock screen graphic, sound effects, and more, creating a layer of passive or active screen security for your computer.
The software gives you a few different ways to unlock your machine, above and beyond a standard password. You can slide left to right across your trackpad, or across any five keys in a row—left to right only—for the same effect. There’s also the option to use “passpattern,” a series of keystrokes that can be rapidly typed or slid across to unlock the screen. You can choose something straight—say, sliding through “QWERTY”—or zig-zag through the keyboard if you choose, so long as you’re quick at typing the phrase. Lock Screen 2 is on sale right now, and will be going up to its full price shortly.
