A closed lid MacBook will sleep unless an external monitor is connected. Amphetamine/KeepingYouAwake/Caffeinate does not change that.

  Mine sleeps with the lid closed unless it’s plugged into power.

    In what context are you using an external monitor without plugging your laptop into power?
    • acomjean 6y ago
      You could forget to bring your power adapter home and have some short tasks to do at home which benefit from large screens.

  Closed-lid + External Monitor + Power Supply = awake Closed-lid + External Monitor + Battery = sleep Closed-lid + External Monitor + Battery + Amphetamine = awake
