Use the NSWindow makeFirstResponder: method, not this method, to make an object the first responder. Never invoke this method directly.
I don't think this method call was ever needed, as in the XCActionBarWindowController's windowDidBecomeKey: method correctly calls [self.window makeFirstResponder:self.searchField]; anyway.
From the documentation:
