F-Engrave on OSX

Is it just me or does F-Engrave run R E A L L Y - S L O W L Y on a mac? I watch the tutorial vids and his PC version seems to scream through the V-Carve plotting whereas mine just sort of plods along at its own pace. I’ve not no slouch of a machine, it’s an 3.4ghz i7. I’m thinking it’s just XCode being slow.

I also see a lot of weird font errors in the interface. Words break out of dialog boxes, or only the top half is in the button or visible. It’s like the text is too big for the interface, but moving the window boundaries doesn’t do anything to fix it. It seems like it was built to use a different native font than what OSX uses.
