I did copy this file:
/Applications/Unity/Unity.app/Contents/Frameworks/Mono/lib/mono/2.0/Mono.Cairo.dll
Into my app assets. The project compiles with no problems, I have even code completion for Cairo classes and methods within the editor, but when trying to execute it says DllNotFoundException: libcairo-2.dll
I am using OSX and I have seen that others experienced this same problem in the past:
Is there any manner to solve this on Unity 4.0 without dirty hacks?
Bests,
