Keyboard input is not possible (TCC deny IOHIDDeviceOpen)

[suzukiplan]

Since keyboard input was not available, I built locally and investigated the cause, and found that the following IOHIDManagerOpen was failing with kIOReturnNotPermitted.

CocoaMSX/Cocoa/CMKeyboardManager.m

Line 83 in f8c41bf

IOHIDManagerOpen(keyboardHidManager, kIOHIDOptionsTypeNone);

The following is a log of the above code when it is executed with the following modifications.

Code

        int result = IOHIDManagerOpen(keyboardHidManager, kIOHIDOptionsTypeNone);
        NSLog(@"IOHIDManagerOpen: return = %X", result);

tested os version is macOS 13.2.1

There was information that kIOReturnNotPermitted occurs when "Input Monitoring" in system preferences (“Security & Privacy” -> "Privacy" -> “Input Monitoring”) is not set.

So I tried setting it that way, but it had no effect.
