keep-screen

Small macOS CLI to toggle screen saver / display sleep / password-delay settings.

Usage

./keepscreen on
./keepscreen off
./keepscreen status
./keepscreen --dry-run on

keepscreen on sets:

• Screen saver: Never
• Display sleep (battery + power adapter): Never
• Password after screen saver/display off: Never

keepscreen off restores the screenshot preset:

• Screen saver starts after 3 minutes idle
• Display turns off after 5 minutes (battery + power adapter)
• Password required after 5 minutes

Install (optional)

chmod +x ./install.sh
./install.sh

Notes

• pmset changes require admin privileges; the script will prompt via sudo.
• Settings apply to the current macOS user (for screen saver and password delay).
