PMUG Prez Art Gorski sends this helpful info, "It turns out that newer versions of Mac OS X protect you from running old incompatible software. These apps are moved to a folder named "Incompatible Software" at the top level of your hard drive. If you have such a folder on your Mac, look in there for the apps that you should update to newer versions." http://support.apple.com/kb/HT3258?viewlocale=en_US&locale=en_US
