I have had a problem with Logos 8 crashing after the Loading Screen comes up. I have reported the problem to Apple, deleted the App and reinstalled, removed all associated files to Logos and reinstalled the app, restarted my computer and still have the problem. It was this way prior to OS upgrade and now after as well. Removed the Logos App after upgrading the OS. I am running it on a MacBook Pro.
Attached is the logging utility log.
