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.
