This question already has an answer here:

Is there a way in the Mail.app to prevent it from previewing pdfs and images in the body of an email.

So that instead you just a get a normal file attachment ?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.


It seems that the display of images (including PDF documents) can be disabled using this Terminal command:

defaults write com.apple.mail DisableInlineAttachmentViewing 1

The display of images/PDFs can be re-enabled by using this command:

defaults write com.apple.mail DisableInlineAttachmentViewing 0
  • Thanks, ill give that a shot, do you know, if wanted how to turn it back on ? - also is this available as a GUI 'preference' that could be toggled on and off ? – sam Oct 11 '13 at 10:15
  • I've added additional information on how to re-enable the images. I do not know of a GUI option for this preference. – Eddie Kelley Oct 11 '13 at 16:03
  • Note that now we must first give Terminal "Full Disk Access" in System Prefs. See apple.stackexchange.com/a/343356/70115 for more detail. – jtheletter Apr 29 at 20:48
