@dminter -That's unfortunate. I agree that a Fusion upgrade from a prior version should not have been a multi-hour science project. Especially on an Intel Mac. That's one reason why I like the full installer for single dot *x.0 -> x.5" releases. Make sure it's as close to a clean install as possible. 

if it's that problematic from official release to official release, I'd hate to think what kind of land mines would be out there from trying to upgrade over a beta release....
