This means already since 04-Mar-2017 (one month ago): * Mac OS X Mountain Lion is no longer supported and the baseline is Mavericks (on macbroy2). This is relevant when producing Isabelle components! * We have an old test machine updated for macOS Sierra in the Isabelle cronjob. * In total the last 4 Apple OS versions are supported, despite old and crumbling test hardware. (I have a new MacMini at home to compensate this a little.)
