Changing IDLE default path

/Applications/Python 3.x/IDLE.app/Contents/Resources

os.chdir(os.path.expanduser(‘~/Desktop/CWD’))

When this cause IDLE to crash with some idiotic message, this is because some file(s) in the folder you set as the default path, contains “import pickle”. Delete this file!
