the >~ and <~ etc. are not created, like in the previous versions. (linux/mac/win). this is id 1702883 in the bugtracker, but it happens on all os, not only osx.
on windows i had a errormessage "allocting font resource" or something like that (sorry, i can not remember the exakt message), during the installation, but only the first time i installed. (maybe some remains of an older pd-extended installation interfered). after unistalling and reinstalling i had no errors.
and on osx the icon looked strange.
bis denn! martin
