Replacicon for macOS makes it easy to replace app icons. You can choose from a set or upload your own. License: €7.99.
If you don’t like the default app icons in macOS for some reason, you can always replace them. Doing this with built-in system tools isn’t exactly difficult, but it’s not very convenient either.
You can simplify the process using the Replacicon utility, which provides icon sets for popular applications. To change an icon, just click on the desired one, and it will be updated instantly.
If needed, you can upload your own images as icons. You can also hide apps with updated icons from the set or exclude non-Dock applications.
