There is something seriously wrong with Clementine on osx, which is unfortunate. Ui consumes tremendous CPU and is laggy as hell. This is a known, reported issue but has not been fixed. It is a shame also because there isn't a decent lightweight player for Mac even close to foobar. Foobar on Mac works well but audio in wine is a mess.
