Peter Lewis of Stairways Software has released Keyboard Maestro 6.4.3, a small update that solves a problem with the macro editor eating too many CPU cycles — especially with Google Chrome actions. The release now updates only visible actions in the editor window, and it fixes incorrect text in the non-edit mode display of Quit/Hide Applications. ($36 new with a 20 percent discount for TidBITS members, free update, 24.8 MB, release notes, 10.8+)
