Many thanks to René & Allan for your kind help!! The warning has been suppressed as per Allan's advice. I installed `pip install PyObjC` and installation directory is 'anaconda' in my home directory. I have Python 3.4 and still I am getting the same error. Earlier I had many files in '/Library/Python/2.7/site-packages' directory and I think those were come by macport installation. I have removed all macport files including '/opt/local' directory. Now the '/Library/Python/2.7/site-packages' directory is empty. I checked the uninstallation script file, there are many files having name pyobjc: yes | pip uninstall pyobjc-core==2.5.1 yes | pip uninstall pyobjc-framework-Accounts==2.5.1 yes | pip uninstall pyobjc-framework-AddressBook==2.5.1 yes | pip uninstall pyobjc-framework-AppleScriptKit==2.5.1 yes | pip uninstall pyobjc-framework-AppleScriptObjC==2.5.1 yes | pip uninstall pyobjc-framework-Automator==2.5.1 yes | pip uninstall pyobjc-framework-CFNetwork==2.5.1 yes | pip uninstall pyobjc-framework-Cocoa==2.5.1 yes | pip uninstall pyobjc-framework-Collaboration==2.5.1 yes | pip uninstall pyobjc-framework-CoreData==2.5.1 yes | pip uninstall pyobjc-framework-CoreLocation==2.5.1 yes | pip uninstall pyobjc-framework-CoreText==2.5.1 yes | pip uninstall pyobjc-framework-DictionaryServices==2.5.1 yes | pip uninstall pyobjc-framework-EventKit==2.5.1 yes | pip uninstall pyobjc-framework-ExceptionHandling==2.5.1 yes | pip uninstall pyobjc-framework-FSEvents==2.5.1 yes | pip uninstall pyobjc-framework-InputMethodKit==2.5.1 yes | pip uninstall pyobjc-framework-InstallerPlugins==2.5.1 yes | pip uninstall pyobjc-framework-InstantMessage==2.5.1 yes | pip uninstall pyobjc-framework-LatentSemanticMapping==2.5.1 yes | pip uninstall pyobjc-framework-LaunchServices==2.5.1 yes | pip uninstall pyobjc-framework-Message==2.5.1 yes | pip uninstall pyobjc-framework-OpenDirectory==2.5.1 yes | pip uninstall pyobjc-framework-PreferencePanes==2.5.1 yes | pip uninstall pyobjc-framework-PubSub==2.5.1 yes | pip uninstall pyobjc-framework-QTKit==2.5.1 yes | pip uninstall pyobjc-framework-Quartz==2.5.1 yes | pip uninstall pyobjc-framework-ScreenSaver==2.5.1 yes | pip uninstall pyobjc-framework-ScriptingBridge==2.5.1 yes | pip uninstall pyobjc-framework-SearchKit==2.5.1 yes | pip uninstall pyobjc-framework-ServiceManagement==2.5.1 yes | pip uninstall pyobjc-framework-Social==2.5.1 yes | pip uninstall pyobjc-framework-SyncServices==2.5.1 yes | pip uninstall pyobjc-framework-SystemConfiguration==2.5.1 yes | pip uninstall pyobjc-framework-WebKit==2.5.1 I also tried by Apple's preinstalled 'PyObjC'. I exported python 2.6 system directory in my bash profile. $ export PYTHONPATH="/System/Library/Frameworks/Python.framework/Versions/2.6/Extras/lib/python/" $ python Python 2.7.10 (default, Jul 14 2015, 19:46:27) [GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.39)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import Foundation >>> It means python recognizes “PyObjC”. Here again I am getting the same error in TexMate. I exported python 2.6 because some 'PyObC' files are missing in python 2.7 system directory.
