Show HN: Adrafinil – keep a lid-closed Mac awake only while agents work
Key takeaways
- It does nothing until an agent acquires it, keeps your Mac awake through a closed lid only for as long as that work lives, and clears the moment the last session releases.
- Keep your Mac awake only while AI agents are working.
- Adrafinil is a macOS menu bar app that prevents the system from sleeping — including clamshell (lid-closed) sleep — exclusively while an AI coding agent has an active session.
It's 3 a.m. You're asleep. The agent isn't — it's still mid-thought in a session you started hours ago, and you've closed the lid over it like an eyelid that won't quite shut. caffeinate and Amphetamine are stimulants: they keep the machine wired forever, whether or not anyone's home. Adrafinil is the eugeroic. It does nothing until an agent acquires it, keeps your Mac awake through a closed lid only for as long as that work lives, and clears the moment the last session releases. It only ever wakes for the work — then you both sleep. ♡
Keep your Mac awake only while AI agents are working.
Adrafinil is a macOS menu bar app that prevents the system from sleeping — including clamshell (lid-closed) sleep — exclusively while an AI coding agent has an active session. When no agent is working, sleep behavior is untouched: close the lid and the Mac sleeps normally.
