- SCardGetStatusChange() and number of card events

This is because Apple replaced pcsc-lite by something else in Yosemite (10.10) and improved it in El Capitan (10.11). I imagine that Apple is still working on this software and it is the good time to propose to Apple to implement features that are present in PC/SC on GNU/Linux and Windows but not (yet) on Mac OS X.
If you think these features are useful you should open bug reports at https://bugreport.apple.com. This will indicate that a feature is important for many users, and not just me. If more users create a bug report then priority for Apple to do something will be higher.
Of course, I would be happy to help Apple implement the missing features.
