I want to change the icon image of an app on the menu bar, for example, the “syncing” image of Dropbox:
However, I cannot find the corresponding image in /Applications/Dropbox.app/Contents/Resources . Another post says changing the menu-bar icon may require the knowledge of Xcode.
Is it possible to change a menu-bar icon without using Xcode? Or is it possible to at least “shrink” the original icon (make it smaller but not disappear) without using Xcode?
