There is no application set to open the URL feed://news.google.com/?output=rss.

Safari Preferences>RSS and select a program in the top drop-down menu (Default RSS reader) - Safari or FireFox would be fine if you don't have a dedicated program. If it's already where you want it, change it to something else, close and repoen Prefs, and change it back.

Hi Roger,

there is no such thing as "Safari Preferences > RSS". I have searched over and over agin, but in Safari 6 there is no "RSS" preference anywhere I looked.

I too have that *stupid* error message, 4-5 times each time my mac wakes up or the Internet connection status changes...

Help appreciated because unfortunately, removing lastsession.plist & History.plist didn't help, although mentionned in an *earlier* thread on this topic : https://discussions.apple.com/thread/5540477?answerId=23719202022#23719202022

I only have Safari 5 so the preference has probably been moved. You should ask in the Safari forum (this one is for questions about these discussions).

Ok that explains it: Safari 6 in fact dropped RSS alltogether. I realise it now: this error message is about RSS, so it must be a stupid leftover from the removal of RSS in Safari 6.

Hope Apple reads this and finds that bug to just dismiss those messages.

They won't. Use this link instead:
