Use Memoji and #images in Messages on Mac
With macOS 11 or later, you can create your own Memoji on your Mac and then send your personalised Memoji stickers — in addition to a variety of emotive images and GIFs — in any message.
Note: Sending images and GIFs isn’t available in all countries or regions.
In the Messages app on your Mac, select a conversation.
To the left of the field at the bottom of the window, click the Apps button , then click one of the following:
Memoji Stickers: Select from a variety of Memoji stickers or create your own Memoji for personalised stickers.
#images: Select a trending image or GIF from the list or search for a specific one that matches your mood.
Optionally, you can drag Memoji stickers on top of a message in the conversation.
If you want to include a written message with the sticker or image, type it in the field, then press Return on your keyboard.
