Reeder has any function to import (mass) feeds?
I 've already exported my feeds in an xml file from google reader.
But, how can I import it to Reeder?
Otherwise, can somebody please tell me a mac rss application who can import all my feeds from a file?
Just sign in to Google Reader when you first run Reeder and it will bring in all your feeds. You will need to sign in to GR anyway for Reeder to work. Reeder cannot import an XML/OPML file.
If you want a stand alone RSS app that can import an XML/OPML file, I know Newsrack, NetNewsWire, Vienna, and Caffeinated can all do this.
