In some environments, the biggest concern about the security of our Mac does not come from the software or the privacy of the tools we use, it comes from unauthorized access while the computer is not in sight. Something that we can solve quite easily by configuring our Mac to lock automatically after a certain period of inactivity.

An indispensable disconnection in more than one situation

We can find Mac computers in the most diverse environments. Depending on the importance of the information managed by the machine, it is necessary to have appropriate protection. One way to do this is to place a password behind the screen saver, but to achieve the maximum degree of protection we must resort to automatic logout.

Once the Mac session is closed, it is practically impossible to attack the computer. Among other things, user information encryption keys have been deleted from temporary memory, making it very difficult to try to access them. Setting a Mac to shut down after a few minutes of inactivity is very simple. We do like this:

From the Apple () menu, we choose System Preferences. We enter security and confidentiality. We touch the padlock at the bottom left. We enter our Mac’s password or use Touch ID to unlock the panel. We touch in Advanced. We enable the Log out after X minutes of inactivity option. We adjust the minutes we want the system to wait. Click OK.

Keep in mind that a shorter time interval will always be safer. Here, however, we will also have to balance that time with conviviality. The idea is that, if we are distracted for a minute with our iPhone, the Mac does not lock, but it does if we have left the office, for example.

Thanks to the automatic disconnection, we can be sure that after our absence from the machine, no one without the necessary authorization will be able to access the information or use or control any infrastructure dependent on the computer. A measure that, although excessive for a Mac that we can have at home, is more than interesting for some places. A very effective measure to protect our Mac.
