hey!

i will change the license asap, should done by the end of the week.
crashes should only occur when switching rapidly between fullscreen and windowed mode using the opengl render. shouldn't be a problem at all if you use java2d or the p2d/p3d renderers (even then i hardly ever see that happening, but i run automated unit tests and they show me it crashes sometimes).

if you only want to hide the menu bar you can also use the jAppleMenuBar library jeff already pointed to. if you don't want to compile it yourself you can pull the needed files out of the fullscreen project:
https://github.com/kritzikratzi/fullscreen-p5/blob/master/src/japplemenubar/JAppleMenuBar.java
https://github.com/kritzikratzi/fullscreen-p5/blob/master/lib/libjAppleMenuBar.jnilib
that of course only works easily if you use processing from eclipse/netbeans/intellij.

you have one last alternative, this should be your preferred way if you _only_ use fullscreen mode and don't want to switch between modes.
just export your app. then go into the app (right click in finder, then "show package contents"),
look for the info.plist and set LSUIPresentationMode to 4 ( http://www.macworld.com/article/55321/2007/02/hidemenubar.html)


hope that helps,
best, hansi.

Ah, ok thanks for the info. So I'll better go with his library, as a .jar runs fine on all platforms.
