While I do not manage large or complex websites, I do use Cyberduck daily. For the most part, I use it to move files back and forth between Linux servers and my Mac, and to edit files sitting on other machines without having to consciously synchronize a local copy. I use most of the features, including bookmarks, file operations, dragging and dropping whole directories, etc. I also occasionally use the directory synchronization feature, which is straightforward but reasonably powerful. I hesitate to call any application bulletproof, but Cyberduck has lasted me through at least three Macs and many OS X upgrades (including High Sierra) without a hitch. The UI is easy to figure out and efficient, and most importantly, makes it clear that I’m accomplishing what I intend. (I’d like it even better if it behaved more like the Finder). Until today, I have taken Cyberduck for granted. But Ducky, today you get the review you have deserved all along.
