Download AppLocker 4.5.0 (Mac) – Download Free

If you share your Mac with other people, you may need to restrict access to certain utilities for various reasons. App lock is a small utility that allows you to put an extra layer of protection on any application.

Set the master password required to start the various utilities

Right off the bat, AppLocker will prompt you to set a master password, which will be stored in the keychain and will be required whenever you want to access the app’s interface or launch any protected utility.

Note that the AppLocker master key can be changed at any time through the relevant status bar menu. The same area allows you to configure applications to start automatically at login, provides a list of protected applications, and includes administrative functions.

Configure utilities to prevent unauthorized use

Whenever you try to launch one of the apps included in the AppLocker list, that app will automatically cover the entire screen, prompting you for a password. As long as you provide the correct key, the appropriate utility will start.

Meanwhile, to cancel the process, just press the Option + Command + Q keyboard shortcut (you will be able to see the combination details in the upper left corner of the panel).

Note that AppLocker automatically locks admin apps, but you can easily add new apps to the list via the built-in lock manager: for convenience, the manager only shows currently running apps.

Apply an additional layer of security to the user interface of any application

Best of all, if you share your Mac with others and you want to make sure your privacy is protected, AppLocker is for you.

AppLocker asks for a master password whenever you try to access its interface, but for all other apps, this only happens when you launch the utility (if you leave any protected app running, AppLocker will becomes useless).
