OS X Mail - disable inline attachments

The easiest and quickest solution!

(this is an old post, to see updates please go to homepage)

The problem

I've been struggling with OS X Mail app for some time now. The Mail app is fast, simple, quick and fun to work with. It is so much more than the other bloated mail client apps.

However, there is this annoying issue with sending image attachments to anyone who is not using Mail app (gmail, yahoo, outlook, thunderbird,...). The images always end up inlined and the result is that the people who receive my emails get this little tiny image without options and need to do extra work to see the image. Also a lot of those people are not tech savvy so they quickly lose patience and move on. The solution is to disable image inlining.

I've tried every possible combination to disable image inlining with options and defaults but without any luck. Google searches didn't provide much except that other people are having the same problem. As good old Attachment Tamer stopped working there was no other way than to code one.

The solution - Anti Inline Plugin

So.. I have waited for OS X 10.10 (Yosemite) hoping that this annoyance will go away. It did not. I finally ran Xcode and wrote this tiny plugin that forces images not to inline.

I can again, finally, just drag and drop images to the email with no worries, yippie!.

If you get into trouble I will gladly assist - just drop a note in the comments section or via email (

Also, I have only tested it on Yosemite so I would appreciate feedback on any older OS X versions, thanks!

    Would like to thank you. Been having this problem myself and this seems to have solved it. Thank you very much!

    Thank you Clive! Your plugin totally does the trick - alleviating years of frustration. You rock!

  • Comment by Mike Hill on 14 November 2014 6:31 pm

    I downloaded this and it was working perfectly. Unfortunately its reverted back to inline :(

    Ive tried reinstalling but no good. Please help!!!

  • Comment by Matt on 18 November 2014 12:05 pm

    Also doesn't work for me :(

  • Comment by Clive on 18 November 2014 8:21 pm

    Hi guys, thanks for the feedback.

    If the plugin doesn't work or has stopped working please try the updated version.

  • Comment by lieven on 19 November 2014 8:38 pm


    thx for the plug in.
    Unfortunately when I add text to a mail (for example singature) next to an image, it is not seen as an attachement in Outlook.
    When I don't add anything, it is seen as an attachement.


  • Comment by Clive on 20 November 2014 12:16 pm

    Hi Lieven, I've tested your scenario and it is working normally.
    Please send me an email with your Mail version so we can continue there.

  • Comment by Billy Catain on 9 December 2014 11:35 pm

    You are a good man! Thank you very much!

    Sadly didn't help on Mail v. 6.6 (1510) on OSX 10.8.5 (12F45). Installed plugin, restarted mail. Have noticed the following is true even prior to installing this plugin: As long as there is nothing else added to the body of the message except a single image, it will be the correct size for the recipient. However, if you anything else to the body of the message (text, another image, etc), it fails. You end up with the wierdly skewed inline picture(s). I have been fighting with this Mac Mail bug for a few years and just use a webmailer if I need to send any photos.

    Thanks for the feedback ppl.

    It works only on Mavericks and newer OS X versions.

    Happy New Year!

  • Comment by Eren on 19 January 2015 4:25 pm

    Would also like to thank you. I have latest version of Yosemite and this plugin works perfectly. There are another dozen people I have sent this to who are also very very grateful.

  • Comment by Tim on 8 January 2015 6:47 pm

    Interesting... the updated plugin was not working for me.

    However, I removed my signature from a new email and tried again and that time it worked.

    Perhaps my signature was forcing the email to be sent in a certain format that defeated the plugin...

    Would be good to be able to still use my signature though...


  • Comment by Petteri on 4 February 2015 4:54 pm

    Thanks, Yours seems to work!

    Before Your Plugin I even tried the terminal command someone suggested:

    "defaults write DisableInlineAttachmentViewing -bool yes"

    But that did not help the main issue: after I installed Yosemite my images were not received by the customers using Outlook. Lets listen how it goes now.

    You're great, man! Thank you for images attached.

  • Comment by Josh on 4 October 2015 1:02 pm

    Works without any problems on 10.10.1 (Beta - 15B22c)!

  • Comment by Michael on 6 October 2015 11:52 am

    Perfect! Thank you very much! :-) That's what Mail needs...

    Installed and worked also on Mac OS 10.11.1 Beta (15B22c)

    Have a great time

  • Comment by Mark Westwood on 12 October 2015 7:37 am

    Working on 10.10.5 thank you!

  • Comment by Jason on 18 October 2015 5:17 am

    It's not so happy with 10.11.1 Beta (15B38b) at the moment ... presume an updated version will become available once the OS moves out of Beta?

    Clive: Yes of course, thanks!

  • Comment by Jonathan Strait on 29 October 2015 5:02 am

    Thank you! Thank you! Thank you! Thank you! Thank you! Thank you! Thank you! Thank you! Thank you! Thank you! Thank you! Thank you! Thank you! Thank you! Thank you! Thank you! Thank you! Thank you!


    I'd been self flagellating without attachment tamer for the last year or so (lots of signatures with apologies and explanations about my image attachments.)

  • Comment by Shannan on 29 October 2015 10:08 pm

    Installed on El Capitan and seems to work in initial testing.
    You, sir, get a big gold star. Thank you, thank you, thank you!
    Apple, are you listening? No, of course not.

  • Comment by Moe on 3 November 2015 8:56 am

    Wow thank you very much Clive!
    You're a true hero :)

  • Comment by Nimrod on 13 November 2015 2:10 am

    This is the only solution that works. Ignore all the Apple fanboys copying that one CLI command around, who can't even distinguish between viewing an email vs. sending one.

    Keep up the amazing effort.

  • Comment by Cees van Giessen on 25 November 2015 1:57 pm

    hi Clive, Thanks a lot. Apple should give you a medal!

  • Comment by Alan on 26 November 2015 10:54 pm

    Works fine for me on Yosemite...BIG Thank you! :)

  • Comment by Robert Peter on 30 November 2015 3:14 am

    Ran it and now my company logo does not show in my email signature

    > Clive: Please, at the plugin page, see instructions how to leave signatures inline. Thanks!

  • Comment by Aaron on 4 December 2015 11:10 pm


    That worked! Too well. I forgot that I have an image in my E-mail signature that I want displayed and not an attachment. How do I revert back to the original Mail settings?



    >> Clive: to leave your signatures inlined please follow the steps at under "Signatures". Thanks!

  • Comment by Stephanie on 7 December 2015 1:51 pm

    Ideal! Have been looking for a solution for an age honestly. However before I go ahead with purchase, I only have one qualm. My signature which is a pdf is also turning into an icon. Is there anyway I can remedy this?

  • Comment by Duane on 11 December 2015 10:13 pm

    Works! But wondering how you uninstall this down the road if needed

    Clive: See uninstall instructions at the plugin page, thanks"

  • Comment by Phil Magistro on 14 December 2015 8:06 pm

    I just found this, installed it and it works perfectly with OS X El Captan.

    Thank you for making this available!


  • Comment by Tom Devine on 14 December 2015 8:42 pm

    Many thanks, Clive --
    This bug, or "feature," has been annoying me for some time now. I'm grateful you found, and posted, a way around it! Apple should take note, and hire you ;-)

  • Comment by Pete on 5 January 2016 12:10 am

    Brilliant worked perfectly at last I can seen attachments

    Thank you

  • Comment by Chris on 12 January 2016 12:48 pm

    Thank you!

  • Comment by Jan on 28 January 2016 9:23 pm

    Thank a lot - it makes work with Apple Mail much more convenient!

  • Comment by K on 29 January 2016 9:54 pm

    Glad to find this piece of software.

  • Comment by John Paulhus on 1 February 2016 6:59 pm

    This plugin is now an essential part of my business communications. It seems like Apple is more and more frequently removing functionality from its products. Thanks to Clive, I can now send image file attachments directly from Mail, and differentiate them from my email signature image file. This saves me time I formerly spent switching between Mail and my Web email server.

    If I could rate with stars, I'd give this 5 out of 5.

  • Comment by Richard Aurisch on 2 February 2016 10:08 am

    Hi Clive,

    Is it possible to choose a text string for the signature image. You have it set to "email-signature"- we use a company logo which usually has "logo" in the file name. If easy to setup you could have as user input like *logo*.

    Is this "email-signature in a plist file that I can change manually.


    Clive: Yes! I've added this option since the version 2.3, thanks for the idea!

  • Comment by Alexandru on 6 March 2016 10:28 pm

    I just tested the plug-in. It works!
    I had no problems. I use Yosemite
    Thank you Clive!

  • Comment by KS on 14 March 2016 5:34 pm

    Thank you so much. So far so good. I'm also using Yosemite.

  • Comment by KS on 14 March 2016 8:43 pm

    Just got the license agreement pop up. All questions answered :)

    Thanks again for figuring out a solution.

  • Comment by Bernhard on 31 March 2016 11:34 am

    Thanks so much! It works perfect!

    Greetings from Germany!

  • Comment by Angela Gast on 8 April 2016 3:37 pm

    Worked like a charm. I'm using El Capitan 10.11.4. Thanks SO much! When will they just fix Mac Mail to act like every other email client?? Odd.

  • Comment by Mark Gilbert on 8 April 2016 11:44 pm

    Great Job Clive. Thank you so much for doing this. Such a simple problem not addressed by Apple's ignorance. works like a dream.

  • Comment by Richard May on 9 April 2016 8:23 pm

    Looks like the perfect replacement for Attachment Tamer which worked perfectly before I upgraded the OS. Nearly had a fit when i got a message saying Attachment Tamer could not be used after I upgraded. Many, many thanks.

  • Comment by Patty on 19 April 2016 8:18 pm

    THANK YOU SO MUCH! I have been searching for a replacement for Attachment Tamer, and now I've found it. I thank you and all my PC and Outlook recipients thank you. No more getting cursed out for my inline attachments :)

  • Comment by Lucie Laverdure on 28 April 2016 3:59 pm

    You made my day !!! :D

  • Comment by Ashish on 25 August 2016 11:46 am

    This is so cool. Thank you. It was a big problem with Apple mail and one of the reasons I was thinking of shifting from it.

  • Comment by Moss the TeXie on 7 August 2016 1:35 am

    Very cool. Just bought the licence.

  • Comment by Carola on 7 September 2017 3:23 pm

    Dear Clive,

    looking for a replacement to Attachment Tamer I found your plugin. I'm running Sierra 10.12.6 and Mail 10.3, and Mail tells me the plugin is incompatible. Any ideas how to fix this?


    Clive: Please use the latest version. Thank you!

  • Comment by Giorgia Faga on 16 October 2018 12:43 pm

    When you could release the version for MacOS Mojave?

    Thank you very much!

  • Comment by Clive on 29 October 2015 5:47 am

    Awesome! Thank you :)
    Keep those pictures attached!
