Tried installing Panda SDK 1.7.0 (todays Mac build) on a 2009 MBP. Mac OS X.6.3. Python:
Python 2.6.1 (r261:67515, Feb 11 2010, 00:51:29) [GCC 4.2.1 (Apple Inc. build 5646)] on darwin
Never had anything Panda installed on it. Downloaded the CG Tools.
Error from my game:
from panda3d.core import loadPrcFileData
Other imports directly in the Python console dont work either. The file in paths.d is there and looks as it should. environment.plist is not found by locate. .bash_profile does not exist, too.
There have been troubles with the Mac install and the paths setting, so propably would not be surprised. But just a few days ago I asked rdb on the IRC channel if a out-of-the-box SDK install should work on SnowL and he said it should, hence this thread.
