Where on my disk can I find the icon used in this dialogue box in OS X?

enter image description here

It may be Security.icns in OS X 10.7.3

enter image description here

I cannot find it in:

  1. /System/Library/CoreServices/CoreTypes/Contents/Resources
    There are only LockedIcon.icns and UnlockedIcon.icns in this folder who looks like the icon in the dialogue box,the size of the icon in the dialogue box is 128x128px, but LockedIcon.icns and UnlockedIcon.icns is 32x32px.


**UnlockedIcon.icns** is **32x32px**

So they are not the same icon.

  1. /System/Library/CoreServices/Finder.app/Contents/Resources/

  2. /System/Library/CoreServices/Problem Reporter.app/Contents/Resources

  3. /Applications/System Preferences.app/Contents/Resources

  4. /Applications/Utilities/Keychain Access.app/Contents/Resources

  5. /System/Library/CoreServices/Certificate Assistant.app/Contents/Resources/

Lock Icon

The lock icon is located in

  1. Install Theme Engine

    Note: You may want to download the released version.

  2. Open the file

  3. Select Security
  4. Drag the icon to the desktop to convert to a png

Finder Icon

macOS just places the app icon in front of it.

I think you want to know where the system icons are stored.

Navigate to:


To do that easily, press cmd+shift+G, then enter the directory above and press Go.

You'll find all the system icons in this folder. Look for the one you want.

  • There are only LockedIcon.png and unLockedIcon.png in this folder who looks like the icon in the dialogue box Jan 11, 2016 at 15:10

    @NickJonathan The image in the dialog is probably composed of the finder icon (/System/Library/CoreServices/Dock.app/Contents/Resources/Finder.icns) and the lock icon you mentioned

  • I have I have replaced the icon of Finder.Where is the Lock icon? Jan 12, 2016 at 3:36

    @NickJonathan The lock icon is LockedIcon.icns . Arc676 suggests the icon you're looking for is composed using both LockedIcon.icns and FinderIcon.icn . I suggest you create it yourself using photoshop or something. Jan 12, 2016 at 3:52
