Send audio clips in a text using Messages on Mac
To leave a group conversation, there must be at least three other participants. Your friends can play the recording right in the Messages window.
If you want to make an audio call instead of sending a clip, see Make a FaceTime audio call.
In the Messages app on your Mac, select a conversation, then click the Send Voice Message button to record a message.
To finish the recording, click the Stop button .
After you send the audio clip, it disappears from your Messages window after 2 minutes. The recipient can still play your audio clip. To preserve the audio clip in your Messages window, click Keep.
