When it comes to protecting confidential files on a Mac, there’s an easy way to add password protection to your files. The feature works just great to lock files and folders on your Mac. However, there’s something that it doesn’t support and it’s locking your apps.

If you want to lock certain apps from being launched on your Mac, you can’t use the standard locking method. Also, there’s no other option on the Mac that lets you keep your apps from unauthorized users.

    This is where two third-party locking apps come into the picture. These apps let you restrict the usage of your chosen apps on your Mac. They let you add password protection to your apps so your apps can only launch if the correct password is entered. Both of these apps are paid ones but you can use their trial versions if you aren’t looking to explore all the features available in them.

    There are many occasions when you might want to lock apps on Mac. Maybe you want to lock your financial apps when you give away your Mac for repairing. Or maybe you want to lock your FTP apps so other users don’t mess up your website files.
