Last Friday this started happening with all my existing apps in Appcelerator Studio. This message shows up in the Appcelerator Platform Services section of tiapp.xml. It happens for apps i have developed and for samples apps that i imported. I had just applied Appcelerator updates and was also fixing a problem with a pop up at program start about having to authorize keychain access for equinox.secure.storage.
