There is a test build for newer macs you can try out. It fixes the wide float and symbol atoms as well as introduces a few things of the old Pd-extended, including the extended font metrics. I increased the object vertical margins slightly due to the somewhat tighter spacing from the metrics and am satisfied the boxes are not too small which was my main issue with the changing the metrics alone. Feedback on this would be helpful, especially from those of you on Linux and Windows.

This is meant as a bug fix for 0.48-1, so no bells and whistles, but my more complex GUIs now render in GOP again.
