Kelsey Heckenkamp - playback issues

So I'm working on a mac and seem to be having playback choppiness when watching my animation in real time. The playblast plays normally, but I'm having the issue now of some of my animation speeding through waay too quick on playblasts due to my issue with choppiness cutting up the frames. I checked to make sure its playing at 24 fps and tried adjusting a few options, but I haven't found anything that works yet. If anyone has experienced this issue and/or has a solution I would appreciate knowing how you solved this. My audio is also now randomly not working on playblasts. It was for most of the project and still works on Maya work screen.
