If you would like to bring a slightly different method of locking your Mac system, especially after the recent security issue enabling any user to be able to change your login password in OS X Lion.
A great application called Lock Screen 2 is available from the Mac App Store that brings a little iOS magic to your lock screen by adding a slider which can be locked using passpatterns. Watch the video after the break to see how it works and if it can help you secure you Mac system a little easier.
Lock Screen 2 is currently on a limited time offer and available to purchase for $1.99 normally $4.99.
