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.
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.
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.
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.
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.
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
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.

This is great. Will check it.

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

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.

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

Nice. I needed this yesterday, and will need it again today.
Does it also make my Mac irritable?
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.

Easier to ask Claude than ask google I guess.
What's old is new again, but I welcome this.

that was true of intel but definitely not of arm macbooks.
Then why do they have fans?
had a coworkers whose laptop keys melted into mush
Um so it is
and ?(personally I have Ruby scripts that check activity on "tmux capture-output" for that)

Yeah, I'll stick with the oneliner.

reminds me of ye old caffeinate
Caffeinate doesn’t prevent sleep with the lid closed.
So now we're naming apps after obscure Modafinil derivatives?
Adrafinil's discovery and use predates Modafinil, I believe.
I admire your pharma knowledge.
you can run opencode inside a docker container and expose it's webui.
Ridiculous bloat.
