Schmitz Shirt Pocket has released [1]SuperDuper 2.8 with support for OS X 10.11 El Capitan, and with some changes to the drive-cloning and backup app's update mechanism. Due to changes to ownership and permissions with the Applications and Applications/Utilities folders in El Capitan (as explained by this [2]Shirt Pocket blog post), you'll either need to upgrade to version 2.8 before upgrading to El Capitan or manually install SuperDuper after upgrading to El Capitan. Additionally, SuperDuper now ups the system requirements to a minimum of 10.7 Lion. (Free for basic functionality, $27.95 for additional features, free update, 2.9 MB, 10.7+) References 1. http://www.shirt-pocket.com/SuperDuper/SuperDuperDescription.html 2. http://www.shirt-pocket.com/blog/index.php/shadedgrey/comments/oh_capitan_my_capitan/ .
