How to use Mac Mail (OSX 10.4) with GUMail: Sending Attachments

Open the New Message window and create your message (see Sending mail if you need help with this).

To add your attachment, Click on the Attach icon.  (It's the one with the paper clip.)

This will bring up the Insert Attachment window.

Find your file in the list, click on it, then click on the Choose File button. Note: You can select more than one file at a time by holding down the Apple key while you click.
