Sort of. Dropbox does add menu items to the right-click context menu on the Mac, and icons indicating whether a file has been synced or not. But if I understand correctly, it does this by installing a kernel extension: https://blogs.dropbox.com/tech/2016/05/going-deeper-with-project-infinite/ https://blogs.dropbox.com/tech/2016/05/going-deeper-with-pro... "Traditionally, Dropbox operated entirely in user space as a program just like any other on your machine. With Dropbox Infinite, we’re going deeper: into the kernel—the core of the operating system. With Project Infinite, Dropbox is evolving from a process that passively watches what happens on your local disk to one that actively plays a role in your filesystem." I think Apple discourages the practice now. There used to be a lot of UI enhancement apps for Mac OS X (called haxies, managed by an app called APE - Application Enhancer). But they were a source of system instability & occasional kernel panics.
