Change Folder Icons

This is the fun part! You'll replace the default folder icons with the cozy themed ones from the Mac_icons/ folder (.png files).

This method works for any folder, anywhere on your Mac. You can customize folders in Documents, Downloads, or any location you like. If you want your setup to match the theme preview, we recommend starting with the folders on your Desktop first.

?

Troubleshooting

The icon didn't change after pasting

Make sure you clicked the small folder icon at the top-left of Get Info (not the large preview). It should have a blue highlight around it before you paste.

The icon looks blurry

Make sure you're using the .png files from the Mac_icons/ folder. These are high-resolution and should look crisp on Retina displays.

I can't paste (⌘V does nothing)

Go back to Preview, make sure the icon image is open, press A then C again. Then try pasting in Get Info. The clipboard might have been overwritten.

I want to go back to the default icon

Open Get Info for the folder, click the icon at top-left, then press the Delete key. The original folder icon will be restored.

I don't see a "Customize" tab

The Customize tab only appears for regular folders. System folders (like Documents, Downloads) may not have it. Try it on a regular folder you created yourself.

The icon didn't change

Press F5 to refresh the folder view. If that doesn't work, try signing out and signing back in.

I can't find the .ico file in the Browse window

In the Browse dialog, make sure the file type filter is set to show Icon Files (*.ico). Navigate to the Windows_icons/ folder inside your extracted theme.

I want to go back to the default icon

For folders: Properties → Customize → Change Icon → Restore Defaults → OK. For system icons: Desktop icon settings → select icon → Restore Default.

I can't find "Desktop icon settings"

Open Settings, search for "desktop icon" in the search bar at the top. Click Desktop icon settings from the results. On Windows 10, it's under Settings → Personalization → Themes → Related Settings.

Can I remove the small arrow on shortcuts?

We don't recommend it. Removing shortcut arrows requires editing the Windows Registry, which can cause system instability. The arrows help you tell shortcuts apart from actual files.
