The magic of folder icons in macOS
If you use a Mac you probably noticed that most of the folders inside your home folder have an icon that matches it’s purpose; Documents, Downloads, Movies, Pictures etc… They are created by default when you setup a user account. A folder directly inside an accounts home folder is automatically given the document icon. Even the home folder itself has a custom icon.
However there’s a folder that’s not created by default. If you do create it, you’ll get a custom icon automatically created for it too.
Just make a new folder in your home folder and name it Developer. As if by magic you’ll get this charming icon applied to it…
Why a hammer? Well if you’ve used any of Apple’s developer tools since the days of Project Builder and Interface Builder up through Xcode you’ll know that it’s a common symbol in the iconography for building code.
