Q: Why do the attachments I'm trying to send open in the body of my email rather than as an attachment icon?

I'm having the same issue as Stophel. This command does not work with Maverick. Any suggestions??

The command in Terminal works fine but I now have a situation where picture files do not show up as files at the other receiving end. The picture files show as small pictures insted of the file icons and are unreadable and cannot be opened. When I convert to pdf files they go through OK. Anything that can be done about this?

I followed Alberto's advice but the problem persists.  What am I not doing?

I have now cut and pasted his command into Terminal three times, does that matter?

I have not tried it in Maverick but there are two commands in this thread.

The first one worked great for me.

If you want to permanently show the attachments as icons, close Apple Mail, open Terminal and issue the following command

defaults write com.apple.mail DisableInlineAttachmentViewing -bool yes

The second command is to reverse the above command.  What command did you past into terminal.

That was the command I used.  I cut and pasted it to be sure I got it right. 

I'm using Mountain Lion, Mail version 6.6

Yes, both commands work on Mountain Lion as described, also on 10.8.5.

No, it does not work in Mavericks.

It's not working on mine, for some unknown reason.  I just had an e-mail from a client saying that attachments are still embedded in the e-mail and are faint and distorted.  I have even tried right clicking the attachment and clicking "view as icon" but, although it changes in my outgoing e-mail, apparently it still doesn't come out as an icon at the other end. 

This has become an embarassment when dealing with clients.  I never thought I would have anything positive to say about Microsoft but I never had any problems with Outlook.  Can I use Outlook on my Mac?  I think it's worth the cost and effort to change because I can't see any benefits from using Mail. 

[Looks like I'm getting bitter]

Maybe there is a misunderstanding. That command changes the way Apple mail displays attachements on your Mac and not how they are displayed on others computers.

If your not satisfied with that program you can certainly adopt Microsoft Outlook for Mac as an alternative.

Thank you.  You have been most helpful. 

I must admit I am more concerned with the quality of information I give to clients than how it looks to me. 

I will probably have to revert to Outlook though it seems to me that, from my experience of Microsoft Word on my Mac, Mac versions of Microsoft applications are inferior to PC versions.  I thought I was getting something special when I bought the Mac, but over the last six months I have been disappointed with every application I have used. 

I entered this command and it turned my attachments into attachment icons but it also turned the photo on my signature into an icon!  Can I now undo this command in Terminal or do I need to put a more specific command in Terminal?  Please help, my business needs my photo in the signature!

If you read through the thread you'll also find the command to reverse it.

This is what I found after re-reading the thread:

"I have not tried it in Maverick but there are two commands in this thread.

Which second thread? Two were posted by Alberto and another by jjw1959. Please repost the correct command to reverse the command Alberto posted orignally.

Thank you.

Close Apple Mail, open Terminal, copy and paste the following command

defaults delete com.apple.mail DisableInlineAttachmentViewing

Reopen Apple Mail and check.
