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.
