I love this app, well, I did love this app - it's the only way I've found to make the Dock background transparent, which is the way it should be.... Anyway, the latest two maybe three updates have killed it, at least on my 10.13.6 iMac - I've tried the full uninstall/reinstall, Safe Mode, all that. Yes, I disable csrutil before installing, but what happens is the Dock just shuts down and reopens in an endless cycle that I can only stop by Force Quitting things in Activity Monitor. Uninstalling cDock is the only fix. I've emailed the developer about this (I'm a paid customer, btw) but have received no replies and I've tried every update.
