On macOS, 3DxWare installs a driver extension that takes the 3D mouse over. With it installed, HidBackend opens the device but receives nothing, so the mouse did nothing in QElectroTech until 3DxWare was uninstalled (discussion #599, PR #1028). Most Mac owners of a 3D mouse have 3DxWare installed. ConnexionBackend asks 3DxWare for the motion instead, through 3DconnexionClient.framework, as Blender does. SpaceMouseListener tries it first. When 3DxWare is not installed, or is installed but its driver is not running, it falls back to HidBackend, so the device works in both setups. Take-over mode stops 3DxWare's own actions in QET, so the view does not move twice. The library is loaded at run time from where 3DxWare installs it: nothing is linked or bundled, and the build needs no SDK. The few declarations are written here, from Blender's GHOST_NDOFManagerCocoa.mm, because 3Dconnexion's SDK headers may not be redistributed. 3DxWare's axes are y up and z away from the user; they are mapped to QET's raw USB convention by comparing Blender's 3DxWare and spacenavd code paths. The release script signs with the hardened runtime, which refuses a library another team signed. misc/qelectrotech.entitlements adds com.apple.security.cs.disable-library-validation (Blender's notarized build carries the same one), and MacQetDeploy_arm64_cmake.sh now passes it to all four signings of the app, including the re-sign inside the DMG. Tested: tst_spacemouseconnexion runs the backend on every platform against fakeconnexion, a stand-in library that answers from its own thread as 3DxWare does: registration, the axis mapping, buttons, other clients' messages, 3DxWare not installed or not running, deletion with a message in flight. Flipping an axis sign or dropping the client check turns it red. realLibrary() loads the real framework when 3DxWare is installed. Linux Qt 6 build with the 3D mouse enabled: all 18 tests pass. Not tested: on a Mac with a real device. The axis signs and whether buttons arrive as a bitmask with current 3DxWare are unverified. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
