With Mac App Blocker, you can password-protect EACH application on your Mac. Keep your apps and your Mac safe. Set a timeout value to automatically exit the protected application so even when you leave your computer unattended, you're still protected.

Features:

Keep it Secure
Kids, co-workers, family members, guests – no worries. You pick which apps will be protected and Mac App Blocker keeps them secure. Tracks failed attempts to access the protected apps - so you'll know when it happened with date, time, and optional photo capture.

Protect Your Privacy
Mail, Safari, Firefox, your favorite journaling application, iPhoto and any other application you use – will be protected. And with the automatic exit feature, you don’t have to worry about leaving the applications running when you are away from your Mac.

Automated Features
Set a timeout value and your inactive application will exit automatically after the selected time period has elapsed. Add a schedule to unblock apps on specific days amd times. Very useful for parents who like to limit computer time.

Protect Your Mac
Add System Preferences to the Mac App Blocker list and feel confident that your settings are protected from accidental (or intentional) misuse. Add Terminal and Activity Monitor to the Blocked Apps list to lock down your Mac even more.

Relax - It's Safe
Mac App Blocker does NOT modify any system or application files on your Mac. It works with the apps and settings that you currently use. You select which apps get blocked and if you decide to remove Mac App Blocker, simply move the app to the trash.

More Automated Features
Network aware unblocking. Add a WiFi network and whenever you're connected to that network, automatically unblock the app or ALL apps with the new Global settings. Global settings also works for the new Scheduling option.
