WhatsApp data on a Mac is primarily stored within the user’s Library folder, specifically in container folders for the desktop application

The main chat databases and media are generally located at

~/Library/Containers/com.whatsapp/Data/Library/Application Support/WhatsApp/.

These files are usually hidden by default, often requiring the use of the “Go to Folder” command in Finder.
Key Locations for WhatsApp on Mac:

• App Data & Chats:

~/Library/Containers/com.whatsapp/Data/Library/Application Support/WhatsApp/

• Other Data Paths:

~/Library/Application Support/WhatsApp/

~/Library/Caches/com.whatsapp/

Media Files: If you have manually saved images or videos, they are typically in your “Downloads” folder, or a specifically chosen folder.
Browser Web Data: If you use WhatsApp Web in Chrome, data is stored in ~/Library/Application Support/Google/Chrome/Default.
Important Notes:
Hidden Files: To access these, open Finder, click “Go” in the top menu, select “Go to Folder,” and paste the paths above.
Encrypted Data: Chat data (ChatStorage.sqlite) is encrypted and not directly readable without specific tools.
Alternative Paths: Some versions or older installs might store data in

~/Library/Containers/desktop.WhatsApp.

You can free up space by deleting the contents of the Application Support/WhatsApp folder, but this will remove the locally stored history from your Mac.
