78:T2bed, ## Description On macOS 15+ (Sequoia / Darwin 24+), status bar item tracking routed through `FrontBoardServices` and `NSSceneStatusItem` delivers `NSEventTypeAppKitDefined` (type 13, printed as `KitDefined`) events when interacting with the menu bar icon. When Qt's Cocoa platform plugin (`libqcocoa.dylib` in `QCocoaSystemTrayIcon`) receives the internal notification from `NSMenuTrackingSession`, it directly invokes `[NSApp.currentEvent clickCount]` without verifying whether the event is actually a mouse event. In AppKit, invoking `-[NSEvent clickCount]` on a non-mouse event raises an `NSInternalInconsistencyException`, terminating Sunshine with an unhandled exception abort: ``` *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid message sent to event "NSEvent: type=KitDefined loc=(0,900) time=555614.8 flags=0x40 win=0x0 winNum=0 ctxt=0x0 subtype=2 data1=0 data2=64"' *** First throw call stack: ( 0 CoreFoundation 0x000000018fb3a8c0 __exceptionPreprocess + 176 1 libobjc.A.dylib 0x000000018f59860c objc_exception_throw + 88 2 Foundation 0x00000001912814d8 -[NSCalendarDate initWithCoder:] + 0 3 AppKit 0x0000000194218f80 -[NSEvent clickCount] + 152 4 libqcocoa.dylib 0x00000001076bb49c qt_plugin_instance + 186712 5 CoreFoundation 0x000000018fabf1a0 __CFNOTIFICATIONCENTER_IS_CALLING_OUT_TO_AN_OBSERVER__ + 148 6 CoreFoundation 0x000000018fb4e394 ___CFXRegistrationPost_block_invoke + 92 7 CoreFoundation 0x000000018fb4e2d8 _CFXRegistrationPost + 440 8 CoreFoundation 0x000000018fa8b3d0 _CFXNotificationPost + 688 9 Foundation 0x000000019117c38c -[NSNotificationCenter postNotificationName:object:userInfo:] + 88 10 AppKit 0x000000019462d154 -[NSMenuTrackingSession sendBeginTrackingNotifications] + 188 11 AppKit 0x0000000194634b98 -[NSMenuTrackingSession beginTrackingSession:] + 644 12 AppKit 0x00000001945e1bac +[NSContextMenuImpl presentPopup:fromView:withContext:animated:async:completionBlock:] + 432 13 AppKit 0x0000000194926880 _NSPopUpMenu + 1992 14 AppKit 0x0000000194925fe0 -[NSCocoaMenuImpl popUpMenu:atLocation:width:view:selectedItemIndexProvider:font:positioningRect:flags:options:] + 432 15 AppKit 0x0000000194925e08 -[NSCocoaMenuImpl popUpMenu:atLocation:width:forView:withSelectedItem:withFont:withFlags:withOptions:] + 96 16 AppKit 0x00000001948e682c +[NSStatusBarButtonCell popUpStatusBarMenu:ofItem:ofBar:inRect:ofView:withEvent:] + 744 17 AppKit 0x00000001948eed1c -[NSStatusItem popUpStatusItemMenu:] + 108 18 AppKit 0x00000001948ef348 -[NSStatusItem _beginExpandedInterfaceSession:] + 600 19 AppKit 0x00000001946ba60c -[NSSceneStatusItem _beginExpandedInterfaceSession:] + 192 20 AppKit 0x00000001946b91b0 __33-[NSSceneStatusItem _setupScene:]_block_invoke.25 + 320 21 AppKit 0x0000000194f06618 __swift_closure_destructor.106 + 28764 22 AppKit 0x0000000194f06794 __swift_closure_destructor.106 + 29144 23 FrontBoardServices 0x00000001ac1a7cc8 -[FBSSceneObserver scene:handlePrivateActions:] + 80 24 FrontBoardServices 0x00000001ac16b864 -[FBSScene updater:didReceiveActions:forExtension:] + 736 25 FrontBoardServices 0x00000001ac193e28 __71-[FBSWorkspaceScenesClient sceneID:sendActions:toExtension:completion:]_block_invoke + 204 26 FrontBoardServices 0x00000001ac14ebbc -[FBSWorkspace _calloutQueue_executeCalloutFromSource:withBlock:] + 180 27 libdispatch.dylib 0x000000018f8625a0 _dispatch_client_callout + 16 28 libdispatch.dylib 0x000000018f84d700 _dispatch_block_invoke_direct + 284 29 BoardServices 0x00000001ac236ca4 __BSSERVICEMAINRUNLOOPQUEUE_IS_CALLING_OUT_TO_A_BLOCK__ + 48 30 BoardServices 0x00000001ac235ac8 BSServiceMainRunLoopSourceHandler + 232 31 CoreFoundation 0x000000018faca944 __CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE0_PERFORM_FUNCTION__ + 28 32 CoreFoundation 0x000000018faca8d8 __CFRunLoopDoSource0 + 224 33 CoreFoundation 0x000000018faca610 __CFRunLoopDoSources0 + 232 34 CoreFoundation 0x000000018fac91e0 __CFRunLoopRun + 832 35 CoreFoundation 0x000000018fba382c _CFRunLoopRunSpecificWithOptions + 536 36 HIToolbox 0x000000019cefc590 RunCurrentEventLoopInMode + 320 37 HIToolbox 0x000000019ceff91c ReceiveNextEventCommon + 492 38 HIToolbox 0x000000019d082380 _BlockUntilNextEventMatchingListInMode + 48 39 AppKit 0x00000001943c329c _DPSBlockUntilNextEventMatchingListInMode + 292 40 AppKit 0x00000001940804fc _DPSNextEvent + 580 41 AppKit 0x00000001948f8748 -[NSApplication(NSEventRouting) _nextEventMatchingEventMask:untilDate:inMode:dequeue:] + 780 42 AppKit 0x00000001948f826c -[NSApplication(NSEventRouting) nextEventMatchingMask:untilDate:inMode:dequeue:] + 292 43 AppKit 0x000000019407390c -[NSApplication run] + 396 44 libqcocoa.dylib 0x000000010769b99c qt_plugin_instance + 56920 45 QtCore 0x00000001071a6ba0 _ZN10QEventLoop4execE6QFlagsINS_17ProcessEventsFlagEE + 588 46 QtCore 0x000000010719d1a8 _ZN16QCoreApplication4execEv + 228 47 Sunshine 0x0000000105028110 _ZN10QtTrayMenu4loopEi + 232 48 Sunshine 0x000000010456f53c _Z14mainThreadLoopRKNSt3__110shared_ptrIN4safe7event_tIbEEEE + 212 49 Sunshine 0x0000000104570d90 main + 5668 50 dyld 0x000000018f633e80 start + 6688 ) libc++abi: terminating due to uncaught exception of type NSException ``` This PR resolves the crash by: 1. Adding `platf::install_event_compatibility_fixes()` in `src/platform/macos/misc.mm`, which swizzles `-[NSEvent clickCount]` using an Objective-C category. 2. For mouse event types (`LeftMouseDown/Up`, `RightMouseDown/Up`, `OtherMouseDown/Up`), the original implementation is called with `@try / @catch` fallback. 3. For non-mouse events (such as `NSEventTypeAppKitDefined`), it immediately returns `1` instead of throwing. 4. Calling `platf::install_event_compatibility_fixes()` early in `src/main.cpp` and prior to `tray_init()` in `src/system_tray.cpp`. ### Screenshot ### Issues Fixed or Closed #### Roadmap Issues ## Testing Added automated unit regression tests in `tests/unit/platform/macos/test_event_compat.mm` (`MacosEventCompatTest`): - `IdempotentInstallation`: Verifies safe idempotent execution across multiple setup calls. - `NonMouseEventClickCountReturnsFallbackWithoutThrowing`: Verifies that querying `clickCount` on `NSEventTypeAppKitDefined` and `NSEventTypeSystemDefined` events returns `1` without throwing `NSInternalInconsistencyException`. - `MouseEventClickCountPreserved`: Verifies that single, double, and right-click counts are correctly preserved for mouse events. Commands run: ```bash cmake --build cmake-build-debug --target test_sunshine -j8 ./cmake-build-debug/tests/test_sunshine --gtest_filter="Macos*:SystemTrayTest.*" uv run --locked lb-update-clang-format ``` All 16 tests in `MacosPermissionsTest`, `SystemTrayTest`, `MacosAudioPermissionTest`, and `MacosEventCompatTest` passed. ## Type of Change - [ ] **feat**: New feature (non-breaking change which adds functionality) - [X] **fix**: Bug fix (non-breaking change which fixes an issue) - [ ] **docs**: Documentation only changes - [ ] **style**: Changes that do not affect the meaning of the code (white-space, formatting, missing semicolons, etc.) - [ ] **refactor**: Code change that neither fixes a bug nor adds a feature - [ ] **perf**: Code change that improves performance - [ ] **test**: Adding missing tests or correcting existing tests - [ ] **build**: Changes that affect the build system or external dependencies - [ ] **ci**: Changes to CI configuration files and scripts - [ ] **chore**: Other changes that don't modify src or test files - [ ] **revert**: Reverts a previous commit - [ ] **BREAKING CHANGE**: Introduces a breaking change (can be combined with any type above) ## Checklist - [x] Code follows the style guidelines of this project - [x] Code has been self-reviewed - [x] Code has been commented, particularly in hard-to-understand areas - [x] Code docstring/documentation-blocks for new or existing methods/components have been added or updated - [x] Tests have been added or updated for new or modified functionality, including regression tests for bug fixes ### AI Usage See our [AI usage policy](https://docs.lizardbyte.dev/latest/developers/contributing.html#ai-usage). - [X] AI tools were used while preparing this PR AI assisted in analyzing the macOS `NSInternalInconsistencyException` crash call stack, implementing the AppKit swizzle compatibility shim, and developing unit tests.
