Short and simple: do both Escape Velocity Nova and Mission Computer work correctly under Mac OSX Yosemite (10.10)? I am still running Mavericks but have need to update for other software reasons, but I don't want to break EVN and MC. I do have a backup, so I could always roll back if it all fails, but I'd rather save the hassle if somebody has a straight answer presently.
I've used EV Nova extensively with no issues. I have used Mission Computer very little with the lack of interesting projects to participate in, but I haven't had any issues so far.
I'm on Yosemite and still use MC quite a bit to mess around and experiment with EVN. No issues other than the usual ones on my end.
