Octave on Mac is really buggy. I was able to compile it with homebrew, but couldn't get the graphics to work.
Mac is basically freeBSD so I am surprised that the Windows version works nicely but Mac seems to be a real problem.
These day, many (or maybe most) young students have mac laptops. It would be great to see a version using the apple graphical libraries. For example, the TexShop program for writing latex. If I knew enough about the graphical libraries, I would volunteer, but I don't.
If possible, please compile a 4.0.1 version and make it a DMG file.
