I wrote an app which (as an accessibility client) is able to grab and translate scroll wheel events. I used this functionality to translate a left-tilt to F5 and a right-tilt to F6 (which then could be configured as shortcut; e.g. to switch between Spaces etc.).This is the code I used to capture the events (trimmed down to work in Playground):import Cocoa import ApplicationServices // The event callback private func cEventCallback(_: OpaquePointer, _: CGEventType, event: CGEvent, additionalData: UnsafeMutableRawPointer?) -> Unmanaged<CGEvent>? { print("Got event ", event, " with type ", event.type) return Unmanaged<CGEvent>.passUnretained(event) } // Check if the process is a trusted accessibility client if !AXIsProcessTrusted() { print("Application is not a trusted Accessibility Client – crashing now^^") print(" (For ScrollWheelMgr to work you need to add/enable it in \"System Preferences -> Security & Privacy -> Accessibility\")") fatalError("Application is not a trusted Accessibility Client") } // Create tap and add it to runloop let eventTap = CGEvent.tapCreate( tap: CGEventTapLocation.cghidEventTap, place: CGEventTapPlacement.headInsertEventTap, options: CGEventTapOptions(rawValue: UInt32(0))!, eventsOfInterest: CGEventMask(1 << NX_SCROLLWHEELMOVED | 1 << NX_OMOUSEDOWN), callback: cEventCallback, userInfo: nil ) let runloopSource = CFMachPortCreateRunLoopSource(kCFAllocatorDefault, eventTap, 0) CFRunLoopAddSource(CFRunLoopGetCurrent(), runloopSource, CFRunLoopMode.commonModes)However in Catalina 10.15 Beta (19A471t) this code does not work as intended: scrolling up and down as well as a scroll-wheel clicks are still registered but tilt events are ignored now. Is there a new event mask that I can use to capture those events again?
