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.

($36 new with a 20 percent discount for TidBITS members, free update, 24.8 MB, release notes, 10.8+)
