Default System Icon Files are Not the Same as Displayed
I noticed something really odd. I wanted to use the default folder icon on my Mac running Big Sur, and edit it to add some custom flair to my icons. I followed the path:
System/Library/CoreServices/CoreTypes.bundle/Contents/Resources
and found my system assets no problem. But when I found the file GenericFolderIcon.icns, that's when I realized something was up.
Here is the image that file contains:
And here is what folders actually look like on my machine (taken from the get info window):
That's a really clear difference! So where is the real location of my system icon assets, and why does my machine have outdated versions of icons being retained?
