The one thing we can try is to check the Console app. It may or may not help us, but it is worth a try. First quit SM. Then go to the Applications -> Utilities folder and launch the "Console" app. Make sure it's set to "All Messages" under the "SYSTEM LOG QUERIES" window. Now launch SM and see if you get any odd messages in the console window for SM. If you do, please email them to us at "support at on-core dot com" (<--make sure to fix that with proper characters).
We are also going to try and load up a Virtual machine with OS X 10.8.5 since we no longer have any Mac's running that old of an OS. That way we can make sure that there is no odd issues with the latest Apple Xcode complier that we use to create the app. We will try to do that sometime next week.
