+  You need to look for files named `*.icns` inside any subdirectory of `CoreTypes.bundle`.

+Apple ships a bunch of high-quality icons of Mac hardware as part of macOS.
+For a long time you could find all these icons in:
+
+<pre style="text-wrap: wrap;"><code>/System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/</code></pre>
+
+but they gradually seem to have split up in newer versions of macOS.
+I was looking for an icon for my 2024 Mac mini in macOS Sequoia 15.1, but I could only find older Mac minis in this folder:
+
+{%
+  picture
+  filename="mac_mini_icons.png"
+  width="600"
+  class="screenshot"
+  alt="A grid of seven Mac mini icons, which is conspicously missing the 2024 Mac mini."
+%}
+
+I found a [thread on Apple's discussion forums](https://discussions.apple.com/thread/254485283?answerId=258385613022&sortBy=rank#258385613022) where somebody was asking for a Mac Studio icon, and somebody suggested looking in a sub-bundle:
+
+<pre style="text-wrap: wrap;"><code>/System/Library/CoreServices/CoreTypes.bundle/Contents/Library/CoreTypes-0003.bundle/Contents/Resources/</code></pre>
+
+That folder doesn't exist on my system (I have `CoreTypes-0003.bundle`, but it doesn't have a `Resources` folder).
+But this was a clue in the right direction!
+
+I used the following shell commands:
+
+```shell
+mkdir -p icons
+
+find /System/Library/CoreServices/CoreTypes.bundle \
+  -type f -name "com.apple.*.icns" \
+  -exec cp {} icons \;
+```
+
+This finds all ICNS files that are anywhere inside `CoreTypes.bundle`, and copies them to a new folder.
+Then I could look for my Mac mini icon in that folder, and I don't have to worry about exactly where it lives.
