I do not have Admin rights on my MacBook at work so I installed Cyberduck to a custom Application folder inside my user home directory after downloading it from the homepage.
Automatic check for updates is enabled, but I will never get a notification about a new version.
When I want to check for updates manually, I get an error with the message, I have to move Cyberduck to the default Application folder. I do not see any reason for this limitation.
