  1. Not working in MacOS 10.9.x either, defaults read shows the key installed but behaviour remains exactly the same.
    I wonder on what OS version did this ever worked.

  2. As of July 29, 2020 the Terminal command did not help me in Catalina even after giving Full Disk access to Terminal. I’m running MacOS 10.15.5, Mail Version 13.4 (3608. on a MacBook Pro (16-inch, 2019).

    Makes it a pain to enter a photo competition that requires attachments rather than inline images.

    Any ideas? Recommendations on alternative mail software?

  3. For Mojave you have to go into System Preferences/Security&Privacy, go to the Privacy tab, and allow Terminal full disk access. Note you will have to click the lock symbol and supply your password.

    • Thanks Bill; your suggestion appears to have worked. I used it in Catalina where the full disk access is the same as Mohave

    • hi this worked fior me in catalina! i allowed terminal full access, then entered ‘defaults write DisableInlineAttachmentViewing -bool yes’
      thanks! I used to have attachments tamer which was great

  4. Copied your command as follows:

    Dad@Gregorys-MacBook-Pro ~ % defaults write DisableInlineAttachmentViewing -bool yes

    This command did not change the behavior. Quitting or not quitting mail first made no difference. Any thoughts as to why this didn’t work in MacOS 10.15.4, Mail 13.4, 2020 MacBook Pro?
