alice-teacher HELP! Mac OS updated and now Alice won't open

[David Riley]

This sounds like an issue that resulted from a somewhat stronger security configuration that is supported in the latest version, called "Mavericks", of OSX.  The operating system is warning that the application has been downloaded from an "untrusted" site so double-clicking doesn't start the application.  One way to work around the problem is to right-click (CTRL-click) on the application and select the Open option from the resulting menu.  This pops up another window that allows the user to "open" (run) the application.

Can anyone please help me figure out how my student can get back into Alice, which was working just fine before he updated his operating system?  The update is called OS X Mavericks.
