Schmitz Shirt Pocket released [1]SuperDuper 2.9, improving bootability of RAID clones and adding a preference to ignore copy errors induced by antivirus programs (which could cause SuperDuper to stop copying files; read more about this issue at this Shirt Pocket [2]blog post). The drive-cloning and backup app also preserved the Scheduled Copies window sort order between launches, fixed intermittent beachballs during launch, and fixed the long-standing upgrade animation bug that prevented the full update text from being visible. Shortly after this release, Shirt Pocket updated SuperDuper to version 2.9.1 with official macOS 10.12 Sierra compatibility and improved quit speed when shutting down or restarting. The app now also requires 10.8 Mountain Lion or later, though version 2.8 (compatible with 10.7 Lion) is still available from the Shirt Pocket Web site. (Free for basic functionality, $27.95 for additional features, free update, 2.9 MB, 10.8+) References 1. http://www.shirt-pocket.com/SuperDuper/SuperDuperDescription.html 2. http://www.shirt-pocket.com/blog/index.php/shadedgrey/comments/superduper_v29_anti_antivirus_macos_sierra/ .
