How is that true? I use my macbook mic occasionally with the lid closed, and an external monitor.

Plus one-ing this - I think the external monitor may be the kicker to keeping the mic active. This drives me up the wall when Google Meet decides to just default to the closed Macbook next to me instead of my already connected Air Pods when joining work meetings.

The closed macbook next to you has infinitely better sound quality than the airpods mic which will sound like you are underwater.

Are you sure it’s the MacBook (T2 or Arm) mic? I imagine you’d sound super muffled if you were trying to use it while closed anyway, so I can’t imagine it’s very usable to yourself?

I just tested this with Voice Memo and can confirm it works at least in that scenario. The recording didn't stop, the mic was just disconnected then reconnected when lid was opened. Using Amphetamine w/ script installed on M1.

Just to point it out, but there’s a native terminal command `caffeinate` that does the same as Amphetamine.

I use the -disu flags
