Just a few creative high-quality replacement icons for Mac, i found these pretty amazing & use them everyday. I hope you know how to replace these icons, but if don’t, it’s simple! Just click “Get info” for the application and copy & paste the replacement icon into the highlighted application’s icon.
If you ever change your mind and want back the original icon of the application, just push “delete”, when the icon is highlighted. So, enjoy!!;)
