QBlocker for Mac

Keep apps from closing by accident with QBlocker

QBlocker is a lightweight macOS utility that stops applications from being closed unintentionally. It provides a straightforward, no-cost way to reduce interruptions caused when you accidentally quit an important program.

What it does

QBlocker lets you prevent specific apps from shutting down when a close command is issued. Its intuitive controls make it quick to enable protection for an application and just as simple to disable it when you intentionally want to quit.

Customization and controls

• Choose which programs you want protected and maintain a list of locked apps.
• Unlock an app instantly when you need to close it without changing your saved preferences.
• Adjust behavior with a small set of preferences so the tool fits your workflow.
• Enable or disable protection quickly from the menu bar for fast, on-the-fly control.

Who benefits

This utility is especially useful for people who juggle many tasks or windows at once and need to avoid accidental closures that break focus or interrupt work. By keeping key apps open, QBlocker helps sustain productivity and reduces the need to restart or recover lost state.

Getting started

Install the app, open its settings, add the apps you want to protect, and use the menu-bar switch to toggle protection as needed. The interface is intentionally simple so you can set it up in seconds and get back to work.
