For some users the receipt validation in Cyberduck 4.4 available in the Mac App Store fails (#7557) if no default network interface is available and the application fails to launch. Users affected can request a donation key at feedback@cyberduck.ch to switch to the free version available from the website. The 4.4.1 update is currently still pending expedited review by Apple for the Mac App Store. Thanks for your understanding.
