AppLocker (Password lock apps) for Mac

Lock Individual Applications

AppLocker lets you protect particular programs on a Mac with a password, so others can use your computer without accessing private apps or data. Instead of securing the entire system, it focuses protection on the specific apps you choose.

Quick setup — password and selections

Getting started is straightforward: create a password, pick which applications to shield, and the tool enforces the restriction. This minimal setup makes it simple to hand your machine to someone else while keeping chosen apps private. Be sure to use a robust, hard-to-guess password — and store it safely so you don’t accidentally lock yourself out.

Benefits

• Minimal configuration required: set a password and select apps to secure.
• Allows guests to use the Mac while keeping selected programs private.
• Targets only certain apps rather than locking the whole computer.

Limitations and risks

• A single password represents a single point of failure: if it’s guessed or forgotten, protection is compromised or unusable.
• Some users have experienced compatibility or access issues caused by the app-level restrictions interfering with other system processes.
• Forgetting the password can prevent you from accessing sensitive applications.

Final assessment

For its intended purpose — restricting access to individual applications — the utility performs adequately and is convenient. However, weigh the convenience against the single-password vulnerability and the possibility of operational conflicts before relying on it as your sole privacy measure.
