I open installer (finally) after reading this thread Then while the Source are being refreshed this pop up on my screen Insufficient Permissions Installer was not installed correctly. It should be run as root : wheel. We will continue but please remember that it may not function correctly. What should i change the permission too?
Run these two commands chown -R root:wheel /Applications/Installer.app chmod 4755 /Applications/Installer.app/Installer More info on commands here
No problem Just remember to delete a few sources just in case. (you may want to also delete RemotePackages.plist in ~/Library/Installer) If it happens again, those two commands have you set.
