Show attachments as icon by default in Mail OS X El Capitan I would like not to show attachments previews in the app "Mail" in OS X El Capitan, but just show icons.
Following the guides, I have tried this command in the Terminal:

defaults write com.apple.mail DisableInlineAttachmentViewing -bool yes


but is seems that, for El Capitan, this doesn't work properly, since in the Inbox folder, attachments aren't shown as icons.

Any suggestions?
I just pasted the following into terminal and it works correctly for me. All attachments appear immediately as icons in El Capitan Mail:

defaults write com.apple.mail DisableInlineAttachmentViewing -bool yes


It appears to be exactly the same as you entered it above. Before entering the command, I closed Mail and relaunched it after the command had been accepted in terminal. Don't know what to say other than it worked for me. Hope this helps someone!
