My mac shut down after 15-20 minutes. Only app running is Vuo editor. Can't tell for sure it's due to it, but I didn't happen in other situations. DiagnosticReports folder doesn't show any vuo-related log. It happened with boh 2.4.0 and 2.4.1. If there's some info I could add, and some other log that could be useful, I'd be happy to submit.
