Why mail opens automatically mac

The convenience of Mail on Mac!

Mail on Mac has a feature called "Open Attachments" that allows it to automatically open attachments, such as PDFs, images, and documents, when you receive an email with them. This feature is enabled by default, but you can disable it if you prefer.

Here are some reasons why Mail might be opening attachments automatically on your Mac:

  1. Default behavior: As mentioned, the "Open Attachments" feature is enabled by default in Mail. This means that when you receive an email with an attachment, Mail will automatically open it in the associated application (e.g., Preview for PDFs, Photos for images, etc.).
  2. System settings: Your Mac's system settings might be configured to open attachments automatically. Go to System Preferences > General and check if the "Open safe files after downloading" option is enabled. If it is, Mail will open attachments automatically.
  3. Third-party plugins: Some third-party plugins or add-ons for Mail might be causing the attachments to open automatically. Check your Mail plugins and disable any that you don't need or use.
  4. Custom settings: You might have customized your Mail settings to open attachments automatically. Check your Mail preferences by going to Mail > Preferences > General and looking for the "Open attachments" option.

To disable automatic attachment opening in Mail on Mac:

  1. Go to Mail > Preferences > General.
  2. Uncheck the "Open attachments" box.
  3. Click "OK" to save your changes.

Alternatively, you can also disable automatic attachment opening for a specific email account by going to Mail > Preferences > Accounts > [Your Email Account] > Advanced > Attachments and unchecking the "Open attachments" box.
