Very buggy program. I've used this for years on High Sierra, but it's a pain in the butt to get it to do the most basic features. Author has a reputation for not replying to user's complaints. The author likes to give the excuse that users don't install it properly by not disabling SIP. But that's one thing this program does properly. It warns the user they must disable SIP, and tells them how. But once it's running, it's problematic, to put it mildly. I had been using this to make my dock transparent, not realizing I can get almost the same effect by tweaking macOS. Now I've discarded cDock completely. It was a total waste of my time. Now the author has the nerve to charge users money for this piece of buggy junk. WOW! That's all I can say, just WOW!
