Since I’m a nerd and a Unity asset dev, I have tons of Unity installations (even if way less than Jean Fabre who is crazy). So here’s a ZIP with different icons (Windows .ico and OSX .icns) for each Unity major, minor and beta version. Red icons are the ones intended for betas.
- January 2018: Added Unity 2018 icons
- May 5 2017: Added Unity 2017 icons
- December 23 2015: Added Unity 4.7 icon
