Send audio clips in a text using Messages on Mac
You can quickly record an audio clip, or voice message, and send it to friends instead of typing your message. 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.
