Mac mail.app has a really annoying habit of displaying attachments inline When viewing email messages, instead of a simple icon you find the contents of your attachments are displayed. It’s particularly annoying when you want to print a short email, which has a huge PDF or image attached to it. You can right click the attachment and choose View as Icon from the context menu, but that only works for a single attachment, in a single message – and that quickly get’s old!
Preventing this behaviour is pretty simple if you are using a version of mail.app prior to 7.1 (the version that comes with Mavericks). Just open the Terminal application and enter the following command:
defaults write com.apple.mail DisableInlineAttachmentViewing -bool yes
If you want to reverse the action, just change the trailing yes for no and re-enter.
Attachment Tamer still best option for Mavericks!
Version 7.1 of mail (the one that comes with Mavericks) and later won’t respond to the same tweak. At the moment there is no known command line tweak to fix the problem, but there is an excellent offering from LokiWare called Attachment Tamer. The Mavericks version of this software is still in beta, but I have been using it for a couple of months (and previous versions since 2007) on my work machine without any problems – it doesn’t yet fix the inline attachment viewing, but importantly it fixes the problems related to sending attachments in a manner compatible with outlook and, well, let’s face it, the rest of the world.
Hopefully the author, Adam Nohejl, will find the answer soon enough.
