So for whatever reason, when I'm mixing audio on logic pro 9, at any given moment my computer will completely shut off and restart deleting all my progress. I'm wondering if this has happened to anyone else because I can't find any forums discussing this bug. It's completely game breaking and I need to fix it in order to do literally any sort of work. I'm running Mavericks on the latest update. Is Logic Pro 9's latest update 9.1.8? That's what I'm using too. I'm using all legit plug-ins so there's no possibility for a virus to have gotten downloaded. Aside from that, I'm running a pretty steady iMac with 20gigs of Ram and a 3.4 GHz processor. Hopefully that's enough information to help narrow down the possibilities. Anyone have any ideas?
