macOS Default Icons Locations: Apple Mac System Icon Paths, ICNS Files, and Assets.car

Fri, 07 Aug 2026 18:00:00 +0200

This guide introduces Icon Finder, a macOS app for finding, copying, and inspecting Apple Mac system icons, application icons, .icns files, folder decoration icons, and Assets.car resources.

Icon Finder brings scattered macOS icon resources into one searchable window.

Why is finding a Mac system icon so difficult?

If you want to change the icon of a small app, decorate a folder, or reuse an icon that already ships with macOS, the hard part is usually not the copy-and-paste step. The hard part is finding the resource in the first place.

Common problems include:

not knowing where Apple Mac built-in icons are stored;
finding one system path in an old post, but having to search again for the next icon;
seeing .icns, application resource folders, and Assets.car spread across unrelated locations;
opening many web pages, Finder windows, and Terminal windows just to compare a few files;
forgetting which path contained the icon you wanted;
finding an Assets.car file without knowing what it is or how to browse it.

The information exists, but it is scattered. A search engine can find a path, yet it does not give you a useful visual catalog of the files inside that path.

Icon Finder puts the search in one place

Icon Finder collects the macOS locations where system and application icons may be found and presents them as a single browser. It lets you:

browse common macOS system icon directories;
browse CoreServices apps, System Applications, and User Applications;
search by icon name or full path;
click once to copy the icon itself;
hold ⌥ Option while clicking to copy the containing folder;
right-click to open the original folder, copy a path, or reveal an item in Finder;
filter by system/user collection and resource type;
import your own folders from Settings;
open Assets.car, search its resources, and preview icon-like entries.

The app opens on All Icons. The sidebar lists the locations, while the main grid shows the matching resources (see Figure 1).

Download and install Icon Finder

To download a packaged DMG, visit the Icon Finder project page and open its Releases section to get the latest version. Open the DMG and drag Icon Finder.app to Drag to Here. The app supports macOS 13 or later.

If this project is useful to you, please consider giving it a Star to encourage the author.

This release is not notarized by Apple. If macOS warns that the developer cannot be verified the first time you open it, use Finder’s Open command or confirm the app in System Settings → Privacy & Security.

If macOS says that “Icon Finder” is damaged and cannot be opened, first make sure the app came from the official GitHub Release. Then remove the quarantine attribute from the installed app in Terminal:

`1`	`xattr -dr com.apple.quarantine "/Applications/Icon Finder.app"`

Open the app again after the command finishes. It removes only the downloaded-file quarantine attribute from this app; it does not modify the application code.

How to find and copy an icon

Find a system icon

Open Icon Finder. It starts on All Icons.
Choose a sidebar directory, or keep All Icons if you do not know where the resource is.
Search by part of the icon name or path.
Click an icon card to copy the icon itself.

You can paste the copied icon into Finder’s Get Info window, Preview, a design app, or another document.

Copy the containing folder

Hold ⌥ Option while clicking an icon. Icon Finder copies the path of the folder containing that icon instead of copying the icon image. This is useful when you want to inspect nearby resources in Finder.

You can also right-click an icon to copy its path, copy its containing folder, or reveal it in Finder.

Keyboard shortcuts

Action	Result
Click an icon	Copy the icon itself
Hold `⌥ Option` and click an icon	Copy the containing folder path
`⌥⌘R`	Reload icon directories
`⌃⌘S`	Show or hide the sidebar

The same filters are available from the toolbar and from the macOS View → Icon Filters menu (see Figure 2).

How to change the icon of an app or folder

Icon Finder finds and copies the artwork. The actual replacement uses Finder’s built-in Get Info workflow. Apple documents the same process in Customise the look of folders and files on Mac.

Change a folder icon

Find an icon in Icon Finder and click it to copy the icon.
Select the target folder in Finder.
Press ⌘ Command + I to open Get Info.
Click the small icon at the top-left of the Info window, below the title.
Press ⌘ Command + V to paste the icon.
Close the Info window.

The small icon at the top-left is the important part. Do not click the large preview in the middle of the window. If Paste is unavailable, the small icon may not be selected or the folder may not be writable.

Change an application icon

The steps are the same for a regular .app:

Copy an icon in Icon Finder.
Select the app in the Applications folder.
Press ⌘ Command + I.
Click the small icon at the top-left.
Press ⌘ Command + V.

macOS may ask for an administrator password when changing an app in the Applications folder. An app update may restore its original icon. System apps and protected locations such as /System and /Library may not be writable; do not disable system protection just to change an icon.

Restore the original icon

Open Get Info again, select the small icon at the top-left, and press ⌘ Command + X, or choose Edit → Cut. Finder will remove the custom icon and return to the default appearance.

What is `Assets.car`, and how do you open it?

Many newer Apple apps do not store every icon as a separate .icns file. Instead, they package icons, colors, sizes, and other interface resources into an Assets.car catalog. It is not a normal image file and cannot be meaningfully previewed by double-clicking it.

In Icon Finder:

Find an Assets.car item in the browser.
Click it to open the catalog viewer.
Search resource names.
Preview icon-like resources, or right-click to copy the resource name and catalog path.

For technical users, the app reads catalog metadata with Apple’s assetutil and generates previews with iconutil. Preview files are created temporarily and removed afterwards; the app does not intentionally maintain a permanent cache. Application locations are limited to .icns and .car so that large collections of ordinary PNG files do not overwhelm the browser.

macOS Default Icons Locations

The following fixed directories are included in Icon Finder. Many macOS built-in icon resources are stored in these folders. The exact contents can differ between macOS releases, and a directory may be unavailable if it is not present or the current process lacks permission.

CoreTypes system icons

`1`	`/System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/`

SCSI architecture resources

`1`	`/System/Library/Extensions/IOSCSIArchitectureModelFamily.kext/Contents/Resources/`

Storage system resources

`1`	`/System/Library/Extensions/IOStorageFamily.kext/Contents/Resources/`

IconsetResources

`1`	`/System/Library/CoreServices/IconsetResources.bundle/Contents/Resources/`

SystemDesktopAppearance resources

`1`	`/System/Library/PrivateFrameworks/SystemDesktopAppearance.framework/Versions/A/Resources/`

IconFoundation resources

`1`	`/System/Library/PrivateFrameworks/IconFoundation.framework/Versions/A/Resources/`

MobileDevices resources

`1`	`/System/Library/Templates/Data/System/Library/CoreServices/CoreTypes.bundle/Contents/Library/MobileDevices.bundle/Contents/Resources/`

CoreServices application resources

`1`	`/System/Library/CoreServices/*.app/Contents/Resources/`

System application resources

`1`	`/System/Applications/*.app/Contents/Resources/`

User application resources

`1`	`/Applications/*.app/Contents/Resources/`

The application paths above mean that Icon Finder enters each matching .app bundle and reads its Contents/Resources/ directory. Application scans focus on .icns and Assets.car to avoid loading every ordinary image in an app bundle.

This is a resource file inside the first directory, not another directory:

`1`	`/System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/Assets.car`

Folders imported through Settings are also scanned recursively. Custom locations can contain .icns, .car, PNG, JPG/JPEG, TIFF/TIF, GIF, BMP, and PDF resources.

Frequently asked questions

Why is a directory unavailable?

macOS versions do not contain exactly the same system resources. System protection and file permissions can also prevent access. Icon Finder does not modify these protected locations; it shows them when they can be read.

What is the difference between `.icns` and `Assets.car`?

An .icns file is usually a directly usable icon resource. Assets.car is a catalog that can contain many sizes, states, colors, and resource types, so it needs to be parsed before its contents can be inspected.

Why can a path exist but the icon be missing?

Icon names and directory contents change with macOS releases, Apple app versions, and installed software. The paths above are a location collection, not a guarantee that every Mac contains the same files. Start with All Icons and search by name, then narrow the result with the sidebar.

Summary

Finding a Mac system icon should not require a chain of scattered web searches, forgotten paths, and a dozen open Finder windows. Icon Finder collects the likely macOS icon directories in one place so you can browse, search, copy, and inspect Assets.car resources in one workflow.

For a quick folder or app customisation workflow: open Icon Finder → find an icon → click to copy → press ⌘I in Finder → select the small icon → press ⌘V.
