SEB 2.3 for macOS is a major update, which improves security massively by supporting the Automatic Assessment Configuration (AAC) macOS Assessment Mode, available from macOS 10.15.4. SEB 2.3 also adds new capabilities, improves the user interface for students and exam administrators and fixes several issues.

• Support for Automatic Assessment Configuration (AAC) macOS Assessment Mode. AAC is used by default if running on macOS 10.15.4 or newer. Assessment Mode blocks various macOS features which shouldn't be accessible during exams. Also no other applications and processes running in the background can access the network while Assessment Mode is active. Optionally, the old SEB kiosk mode can be used also on latest macOS versions (see Preferences / Security / "Use Assessment Mode (AAC) if available", settings key enableAAC), as AAC doesn't support optionally enabling features like like screen capture/sharing, Siri and Dictation.
  
• New battery indicator control in the SEB Dock (automatically displayed when using Assessment Mode on devices with battery, as the macOS menu bar is hidden by AAC).
  
• Full compatibility with macOS 11 Big Sur.
  
• Native support for Apple Silicon.
  
• Preferences window can be opened by holding the option/alt key while starting SEB (also when dropping a SEB configuration file onto the SEB icon).
  
• New options to enforce using the internal (built-in) display of a MacBook or iMac and allowing to use the external display on a Mac without built-in display (Mac Mini, Mac Pro).
