Yesterday i updated my Apple Power Book to Version 10.13.3. Unfortunately since that, I cannot use Cyberduck anymore. I already deleted the program twice and installed again. But even doing so the problem is still there. The program opens as usual; but trying to connect with a server the information "Operation not permitted (connect failed). ...". Opening Cyberduck on another Mac within the same network still works fine. I've already contaced Aplle but they said that I will have tos solve the problem with you. Do you have any idea what to do?
Duplicate for #10237. We can reproduce this issue – thanks for notifying us about this severe issue. It looks like the codesigning security entitlements are not properly applied by the Mac App Store download. We are in contact with Apple Developer Support to get a resolution as soon as possible.
