QuickTime Player crashes on macOS Sonoma

It has been reported that QuickTime Player often crashes when a device is connected to a secondary display - e.g., when sharing content in a classroom from a macOS laptop or podium. This known issue primarily impacts macOS Sonoma OS and has not yet been resolved by Apple.


  • Use IINA Media Player instead of Quicktime whenever presenting video on a secondary display.
  • Wait for Apple to resolve this issue with Quicktime Player.
