After macOS update to 26.5 (25F71), I observed the Return key does not work in interaction with Terminal’s “New Remote Connection” window, but only the first interaction with the window. Launch Terminal Open New Remote Connection window Use the keyboard or mouse to select a Service, like Secure Shell Pick a Server, either static or Discovered Pressing Return used to launch the appropriate command (because the Connect button is lit/colored), but now the system error sound occurs. Either the mouse must be used on this first interaction, or I have to use keyboard shortcuts (tab) to highlight the Connect button where I can press either Space or Return. After that first interaction, the Return key functions per normal UI rules.
