Legendary Windows developer Dave W. Plummer has shared details and screenshots of a version of Task Manager for Apple Mac computers. However, “Activity Monitor blows,” asserts Plummer, in response to people asking why he would port the classic Windows utility to the fruity computer. Hey look, it's your old friend Task Manager... on the Mac! In case you missed it, Plummer was the original dev behind Windows Task Manager when it debuted as a lean and mean 80KB accessory. In this Tweet, the dev asserts that “Microsoft very graciously sent me the source code to XP Task Manager along with permission to share/demo it.”
