If in our workplace we use a Mac, to which only we can have access, but we continually find ourselves going in and out of the office, or repeatedly moving away from our Mac, exposing all the information that we have stored on it, we must always remember to put the Mac to sleep or turn it off so that no one who does not have knowledge of the password can access all the information stored in it.
This process is likely to become a nuisance and that on more than one occasion it will pass us by. Fortunately we can make use of other solutions, solutions that take care of this task automatically. Guardian Angel is one of them, an application that takes care of putting our Mac to sleep if we move far enough away so that our Mac's bluetooth connection is not within reach of our iPhone.
In order to function, Guardian Angel makes use of the low-energy bluetooth connection of our Mac and our iPhone, so that this automatic locking system will not affect the battery life of our iPhone. But this application not only allows us to block the device if we move away, but also it also allows us to unlock it when we get close to it, avoiding that we have to enter the password again when we sit in front of him.
Guardina Angel also allows us to configure our Mac so that when we move away, instead of going to sleep and preventing access, it begins to perform tasks of various kinds, so that we take advantage of the time that we are not in front of the computer to perform tasks that require time that we cannot lose when we are in front of the Mac. This application is available for download for free, both the version for Mac and the one available for Apple's iOS ecosystem.
