since downloading the Public Beta 2 of El Capitan I have encountered two issues with other third party calendar trigrams. Fantastical 2 Crashes on Startup and Desktop Informant (another program which is currently in a Pre-Release) Fantastical 2 just crashes on startup, making it at this point unable. It DID work just fine in the first public beta as did Desktop Informant. Desktop Informant, while in public pre-release version, was working just fine in the first public beta, but since installing the second public beta it cannot access the Apple Calendars. The only calendars that it can access are the Anniversary and Birthday calendars, which I believe are generated from the Contacts application. The other applications that I have that use the Apple Calendars are all working just fine and those include BusyCal 2 and OmniFoucus 2
