Hi Casey,
I'm running the same hardware and haven't had any hard freeze issues with PS 1.02. I'm on 10.9.2 Mavericks, btw.
Does it work fine in older versions for you? Are you trying to run an extreme process? (ie. ultra res, lots of images)
You could try opening the Mac Console app and keep an eye on it when you fire off your process to see if something unusual appears before the whole thing locks up.
Cheers, -Chad
