How to Delete iMessages on Your Mac

If you simply want to remove the Messages app from your Mac, there are a few ways to do it.

You've provided a comprehensive guide on deleting iMessages on Mac! Here are some additional points and clarifications:

How to Delete iMessages on Your Mac
Deleting Messages:

• Confirmation Prompt: Remember, deleting messages is permanent, but you'll usually receive a confirmation prompt before the action is complete.
• Alternative for Deleting Multiple Messages: Instead of holding Command and selecting messages, you can also click on the first message, then Shift-click the last message you want to delete for a faster selection process.   

Deleting Conversations:

Keyboard Shortcut: You can also delete conversations using the keyboard shortcut Option + Command + Delete (⌥⌘⌫).

Deleting Attachments:

• Finder Navigation: Instead of copying and pasting the path, you can navigate to ~/Library/Messages/Attachments by going to Finder, selecting Go > Go to Folder from the menu bar, and typing the path directly.
• Selective Deletion: While dragging the entire folder to the trash deletes all attachments, you can also browse individual folders within Attachments and delete specific files as needed.

Automatic Message Deletion:

• Settings Location: Automatic message deletion is configured within the Messages app itself. Go to Messages > Preferences > General. There, you can set messages to expire after 30 days or 1 year.
• iCloud Impact: As you mentioned, automatic deletion on Mac will also affect messages on other devices if Messages in iCloud is enabled.

Additional Tips:

• Archiving vs. Deleting: If you want to keep conversations for reference but remove them from your inbox, consider archiving them instead of deleting. Archived conversations are accessible in the Messages app's search bar.
• Disabling Messages in iCloud: Disabling Messages in iCloud settings prevents future messages from syncing to your other devices, but it won't delete existing messages on them.
