Can you find any related output in the system.log (/Applications/Utilities/Console.app)?

It looks like the installation of version 4.4.4 of Cyberduck with MacUpdate Desktop failed and you are still runnning an older version. Can you try to manually download from (https://update.cyberduck.io/Cyberduck-4.4.4.zip)(https://update.cyberduck.io/Cyberduck-4.4.4.zip).

The default protocol is possibly overridden to null in your user preferences. Can you try to reset the preferences to factory defaults by entering

defaults delete ch.sudo.cyberduck 

in a Terminal.app window.

New ticket in #8115.

RESOLVED!!!

Can you please try to deinstall both KeyCue and the SIMBL.osax
scripting addition. I suspect there is an interoperability issue with
these.

Please note I have put these two items back into their prior locations; clearly it was something in the defaults. I snapshotted each page of the preferences before initializing and in comparing I note that the SFTP protocol element was inexplicably assigned to VLC. Additionally, SFTP is the only thing I use in the only bookmark operable.

Thanks so much for your aid!

Great to hear. Can you please attach the preferences file (ch.sudo.cyberduck.plist) that caused the issue. Many thanks.
