The problem usually has to do with convenience. It’s inconvenient to lock the Mac, inconvenient to require a password to use the Mac, and more inconvenient to enter a password. Here’s a way to lock up a Mac with a single click and save a few steps in the process.
Fast. User. Switching.
As noted before, there are a number of ways you can secure your Mac, whether stepping away from the Mac for a meeting, a bathroom break, or out to lunch.
For example, open System Preferences, click on the Security & Privacy button, click on General, and click the Require Password button to unlock a Mac after sleep or when the screen saver begins.
That’s an easy and free way to add an extra layer of security to you Mac when you need it.
It’s also automatically implemented which is a big time saver. If you set your screensaver to startup when you move the screen pointer to a hot corner, it’s also instant.
Of course, most of us have Automatic Login enabled, so a thief would only need to restart the Mac to gain access. Even better than all that is the free security app called MacLoc.
This Menubar utility gives you one-click security. Click MacLoc and it activates OS X’s Fast User Switching. That makes it appear as if you’ve logged out from your Mac.
Enter your username and password and your Mac is right back where you left it. We usually recommend that Mac users not activate Automatic Login as that settings makes your Mac the most vulnerable.
MacLoc is free and could not be simpler to use. Just click.
