Unidentified Developer?

If you received a warning about Teacher Studio being from an “unidentified developer”, you will need to right-click on Teacher Studio and click on the “Open” button to bypass Apple’s new security measures (aka Gatekeeper). Once Teacher Studio launches, you will not see this warning again. We did sign the app with our developer key, but apparently it did not work. We will have this resolved soon.

Edited: this has been resolved.
