Try Lid Keeper on your own Mac. This is an early development preview; the signed, notarized release is still being prepared.
This preview is ad-hoc signed, without an Apple Developer ID or Apple notarization. macOS may block it. Read the security details and installation guide first. You can wait for the notarized release if you prefer.
One download. Start with the trial.
Seven days of Plus begin after your first successfully verified session. No account or payment card is needed. Afterward, Free remains available for sessions up to 20 minutes, with unlimited manual restarts.
The trial includes sessions up to four hours, custom durations, saved presets and a keyboard shortcut. Plus purchasing is not open yet. Ordinary sessions and recovery run locally.
Check your setup
This package supports Apple Silicon Macs running macOS 14 or later. An Intel build is not available. Start with a five-minute session and check your audio, apps and closed-lid behavior before leaving a longer job running.
Keep your Mac on a ventilated surface. Sessions stop at low battery, high thermal state or the time limit. These controls cannot guarantee compatibility with every Mac or app.
