Hi;
Have a system very similar to yours, running Mavericks. I'm able to run VTM 1.1.13 ok. But if you're having problems, try downgrading to RTAS 1.1.9.9. In my experience, not all AAX plugs work properly. If you're given an option, a lot of times the RTAS version works more consistently, especially when confronted with that pesky 'out of memory' warning.
