In its second lawsuit this month to thwart unannounced products, Apple is suing three men for illegally distributing beta versions of Mac OS X 10.4 (Tiger) on a file-sharing Web site. Apple claims in its suit that the men released two different versions of Tiger in BitTorrent format on or about Oct. 30 and Dec. 8 of this year. “Members of Apple Developer Connection receive advance copies of Apple software under strict confidentiality agreements, which we take very seriously to protect our intellectual property,” the company said in a statement.
