Attachments as icons in Apple mail
I just want to share how to overcome the annoying problem that pdfs and jpgs are displayed as previews always in apple mail (high sierra). You can start the terminal and give the command:
defaults write com.apple.mail DisableInlineAttachmentViewing -bool YES
All attachments coming up now as icons. You can re-enable it using
defaults write com.apple.mail DisableInlineAttachmentViewing -bool NO
I don't like the preview of attachments in emails, it takes away overview and you can't see the filename. Apple should leave the setting to the user on a better accessible point in the AppleMail settings.
I found this here:
