App icon
Morgue lets you pick the icon it shows in the dock and Applications folder.
Choosing an icon
- Open Settings → Appearance.
- Choose from the available icon styles.
- The dock icon updates to match.
How it persists
Your choice is saved and re-applied automatically every time Morgue launches — including after an update — so it sticks.
Resetting
Pick a different style at any time to change it back; there's no lock-in.
macOS icon cache
macOS aggressively caches app icons. If a change doesn't appear everywhere immediately, it usually catches up shortly or after the next launch.
