I’ve often wondered about the thermal performance or running a MacBook with the lid closed. One argument is that the reduced surface area from a closed lid increases temperature. Others argue that not running & rendering the display (and thus GPU) generates less heat. I’m not sure who to believe.

This is great. Will check it.
Recently I bought a usb-c empty external monitor card to prevent mac from going to sleep. There are many of these external monitor simulators on Amazon.
I still see the laptop go to sleep many times with the external monitor simulator.
The dummy display enables “clamshell mode,” which lets your MacBook stay awake even with the lid closed, provided that it’s also on AC power. If the MacBook is not connected to power, the clamshell mode isn’t activated and it will sleep normally.
Adrafinil simply disables the global sleep without spoofing hardware, and re-enables it once the agent is done working, the temperature is too high, or the battery is low.

My requirement was to keep the laptop on with the lid closed. Sleep normally when idle but wake up when a nomachine request comes in.
I will see how this app fits into my specific need.
I have to check this on Mac Sequoia 15.7

The app is built for 26+, as I never tested it on earlier versions. It won’t solve your specific case, though, as it only prevents sleep. It won’t wake it once it’s already sleeping.

Can't you just use a hot corner configured as "prevent sleep"?

How does it sleep when the agent is done working with the hot corner?

Have the agent write an app that moves the cursor our of the hot corner and trigger it when done.

Thank goodness. I can’t leave my laptop for a second unattended because my cat loves nothing more than to dance on the keyboard. I’ve need something like this.

For MacOS, keep awake with:
sudo pmset -a disablesleep 1
Reset back:
sudo pmset -a disablesleep 0

This is exactly what the app does, except it ties it to agent activity and re-enables sleep once the turn ends, the laptop is close to overheating, the battery is low, or on a timer.

Does it also make my Mac irritable?
kageroumado 2 hours ago [-]
Probably less irritable than amphetamine~

But Amphetamine has an option to end when an app closes. I’m just so confused why everyone using ai is reinventing solutions that already exist.

Claude Code or Codex (normally) don’t close the terminal window after a turn ends, they wait for the user’s reply.

I think the same...It happend to me that I just ask Claude to build whatever I need for my personal very specific use case without looking what else it's outhere

Everyone dreams about making the next cool AI tool and doesn't bother checking if someone has already made the same thing years ago without the word "AI" in the description

In order to get the same behavior with Amphetamine you’ll need to:
1. Install it from the AppStore (no brew, no GitHub)
2. Not forget to enable lock on lid close
3. If you ever connect/disconnect power while the lid is closed without the optional “Power Protect” system, the MacBook will sleep. The system is a script and a configuration file making sudo pmset -a disablesleep passwordless.
4. Add hooks to Claude Code configuration that will use Apple Script to start and stop Amphetamine sessions. For Codex you’ll have to make a script that will watch process activity to know when a turn ends.
It’s not like Amphetamine can’t do the same, it’s that this app is made specifically for AI agents and nothing else.

Easier to ask Claude than ask google I guess.

What's old is new again, but I welcome this.
I used to do this 15 years ago to keep listening to music from my laptop (one of the white chiclet ones) in my backpack, can't remember the name of the app I used then.
One caveat, your laptop cannot cool inside a backpack, it will overheat and shut down anyway. This happened to me several times.

It has a setting for thermal cutoff that you can set to something like 60º C. Sleeping will stop heavy work (like a build) before it leads to overheating.

(personally I have Ruby scripts that check activity on "tmux capture-output" for that)
