Keep a Cursor agent running on your Mac
A Cursor agent working through a long task gets suspended the moment your Mac sleeps. Here is how to keep a Cursor agent running on your Mac, even with the lid closed, while safety thresholds stay in control.
What interrupts a Cursor run
Cursor's agent runs locally, so it pauses when the Mac sleeps from idle or a closed lid.
Long refactors and multi-step tasks are exactly the runs you do not want to babysit, which is when a sleep interruption hurts most.
The LidRun workflow for Cursor
LidRun detects Cursor and holds the Mac awake while the agent works, so you can step away or close the lid.
Every keep-awake decision is gated by battery and thermal state. When a threshold trips, LidRun lets the Mac sleep rather than overworking it.
Recommended settings
Stay plugged in for long agent runs and leave battery auto-sleep on as a safety net.
Use a session timer so the run has a clear upper bound even if the agent stalls.
LidRun keeps your work running with the lid closed, with battery and thermal safety built in.
Frequently asked
Yes. LidRun detects Cursor among many dev and AI tools and keeps the Mac awake while it runs.
Yes, with keep-running mode on. Battery and thermal thresholds decide when the session should end.
LidRun reads thermal state continuously and surfaces it in the menu bar, and cooling profiles respond where the hardware allows.
