Similar Tools
Cuukit Screen Lid differentiates itself from other macOS utilities by combining screen covering with a custom PIN and system wakefulness in a single, privacy-focused application. Its competitive landscape includes various tools that offer partial or alternative solutions for keeping a Mac awake or locking its screen.
It is a highly customizable keep-awake utility that can also trigger your Mac's screen lock after inactivity or during a session.
While Amphetamine effectively keeps your Mac awake and can lock the screen, it uses the standard macOS password or Touch ID for unlocking, rather than a custom four-digit PIN like Cuukit Screen Lid.
MakLock provides a full-screen blur overlay on all monitors to protect privacy when specific applications are locked, using Touch ID, Apple Watch, or a backup password for authentication.
MakLock focuses on locking individual applications with a privacy overlay rather than the entire system screen with a custom PIN. It offers a password fallback, but it's primarily an app locker, whereas Cuukit is a system-wide screen cover.
KeepingYouAwake is a simple menu bar utility that prevents your Mac from sleeping, and when combined with the native macOS lock screen shortcut, it achieves both functions.
This solution requires two separate actions: activating KeepingYouAwake to prevent sleep and then using the macOS keyboard shortcut (Control+Command+Q) to lock the screen. Cuukit offers both functionalities within a single application and a custom PIN.
This method uses the built-in `caffeinate` command in Terminal to prevent sleep and the native macOS lock screen shortcut for privacy.
This is a command-line and keyboard shortcut workflow, not a graphical application like Cuukit. It lacks a custom PIN and requires manual execution in Terminal, offering a less integrated user experience.
