CGEvent not working with mouse (macOS 15.1 Sequoia Beta)

So basically I'm making an auto clicker for Mac in Xcode 16.0, but the CGEvent doesn't seem to work. I searched the internet and viewed documentation, but I couldn't find much about it. Here's my code

let source = CGEventSource(stateID: .hidSystemState)
let mouseLocation = NSEvent.mouseLocation
        
CGEvent.init(mouseEventSource: source, mouseType: .leftMouseDown, mouseCursorPosition: mouseLocation, mouseButton: .left)?.post(tap: .cghidEventTap)

usleep(100_000)

CGEvent.init(mouseEventSource: source, mouseType: .leftMouseUp, mouseCursorPosition: mouseLocation, mouseButton: .left)?.post(tap: .cghidEventTap)

I also tried moving the mouse but nothing. I also gave it access to control my computer (in settings > privacy & security > accessibility > my app) as it is required to do everything with mouse and keyboard. But still no.

Solution

Ran into this as well - seems like Sequoia has started validating the timestamp of the event, try constructing the mouse event via CGEvent.mouseEvent (since it does not seem that any of the CGEvent.init signatures allow providing a timestamp) and provide a correct timestamp derived from the system uptime and also a proper event number (even thought seems that only setting a proper timestamp is fine as well). At least that is what solved this for me.

People seem to be requesting sample code, so here goes (even though it's a trivial call to the linked initializer):

NSTimeInterval timestamp = [[NSProcessInfo processInfo] systemUptime];
NSEventType eventType = NSEventTypeLeftMouseDown;
NSEventModifierFlags flags = 0;
CGPoint point = CGPointMake(0, 0); // correct point
NSInteger windowNumber = 0; // correct window nummber
/*
     seems like it works w/o this, but ideally properly store and increment
     a event number counter
*/
NSInteger currentMouseEventNumber = 0;
NSEvent *mouseEvent = [NSEvent mouseEventWithType:eventType
                                         location:point
                                    modifierFlags:flags
                                        timestamp:timestamp
                                     windowNumber:windowNumber
                                          context:nil
                                      eventNumber:currentMouseEventNumber
                                       clickCount: 1
                                         pressure: 1
];
