Python 2.7.3 installed on Mac OS X 10.7.5 and 10.8.2 (in two separate machines). When pygame v1.9.1 release ( was installed, IDLE  or pyCharm keep giving the following annoying error.
File “<stdin>”, line 1, in <module>
  File “/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pygame/”, line 95, in <module>
    from pygame.base import *
ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pygame/, 2): no suitable image found.  Did find:
    /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pygame/ no matching architecture in universal wrapper

There are some rather complicated solutions. But I eventually found out that it is a rather simple solution. Basically the problem is python 2.7.3 contains and installs both 64-bit and 32-bit binaries, and the default binary is 64-bit in the newer OS X versions (10.6 and up). Pygame is only compatible to 32-bit Python hence the error message.

To solve the problem, go to where the Python framework is installed, which can be found at

There are two files (NOT the shortcuts), one called python2.7-32 and the other is python2.7. Change the name python2.7 to python2.7-64 (this is the 64-bit file), and then rename python2.7-32 to python2.7.

Now the error is gone.

If you wish to run IDLE in 32-bit as well, you can run this comment from the Terminal:$ arch -i386 /Library/Frameworks/Python.framework/Versions/2.7/bin/idle2.7 -n

This is just optional.

To get pygame to work on OSX 10.6-10.8, you do not need to homebrew a separate pygame installation file. You certainly do NOT need to follow the Mountain Lion install instructions as detailed in here.
