When using the integrated fullscreen mode combined with the system one (clicking the green "maximize/fullscreen" button), the emulator will crash when it loses/regains focus, for instance when changing to and from another full screen app. Here is the crash log provided by the os: http://pastebin.com/6aJj2LwJ

This crash occurs in macOS Sierra due to the internal changes to its version of fullscreen mode. This crash does not occur in macOS El Capitan and earlier.
This crash has already been fixed in [r5349]. You can use a nightly build of DeSmuME with this bug fix from our Downloads page at http://desmume.org/download.
If you need to continue using v0.9.11 on macOS Sierra, then you cannot use the green maximize/fullscreen window button. Instead, you must enter fullscreen mode using the menu item View > Enter Full Screen, and then exit fullscreen mode with the menu item View > Exit Full Screen.
