i'm on osx, so using .pd_darwin extension. 

i put it in my extra folder, made a demo patch in pd, and it works fine. 

only problem is, when i shared the .pd_darwin with 2 friends, it didn't work for either of them. (i checked they had put it in the extra folder)

does anyone have an idea what might be wrong? 

what sort of info can i provide to track down the issue?

i built for universal architecture. 

friends are both on osx 10.10 same as me.  

what could be the issue here?
