Start with intent
Choose the work.
Start an app-aware session, use a timer, or keep control manually. MacStayOn protects only the session you chose.
Native menu-bar control for Mac
MacStayOn
Close the lid.
Keep the work running.
Let Codex, ChatGPT, development servers, exports, and other approved work finish without keeping your display awake.
Native Swift Battery and thermal safeguards
A session with judgement
It stays awake for the work.
Not a moment longer.
MacStayOn keeps one clear promise: protect the task you selected, then step aside when it is complete or a safeguard says stop.
Close the lid
Let it keep moving.
Your display can sleep while approved work continues. No permanent browser runtime or background Node server is required.
Stay protected
Limits watch the session.
Battery cutoffs and thermal-pressure safeguards decide when MacStayOn should release its own power assertion.
Return with context
Come back to done.
See whether the task completed, a safeguard stepped in, or the session is still waiting for you.
Quietly capable
Built to finish the job.
Designed to know its limits.
Task-aware by design
Auto mode watches supported work states, including active and queued tasks, before deciding a session is finished.
Your battery sets the boundary
Choose a cutoff that releases MacStayOn before background work uses more charge than you intended.
Thermals stay in charge
MacStayOn responds to macOS thermal pressure without terminating the apps or system services you rely on.
What MacStayOn actually monitors
Clear boundaries.
Explainable decisions.
See the limited signals it uses, how safeguards respond, and what the 24-hour local audit records.
MacStayOnPrivacy boundary
It reads state, not content.
MacStayOn checks whether approved work is active, complete, or queued. Prompt text, task content, project files, and output stay outside its view.
