Shirt Pocket has released version 2.7 of its SuperDuper drive-cloning and backup software with support for the OS X 10.8 Mountain Lion’s Gatekeeper security feature. Additionally, the new release should start more quickly (even with unresponsive network volumes) and copy files faster, and it improves the copying of active files from apps that rapidly create and delete files during a backup (which could cause some files to vanish from a backup). The status window has been updated to show what’s going on while larger files are being copied, diagnostics have been improved to more accurately return errors when drives can’t be read or written to, and local Time Machine snapshots (.MobileBackups) are no longer copied to reduce backup failures. SuperDuper has also been updated to support the latest version of Growl (which also provides support for Mountain Lion’s Notification Center). However, SuperDuper isn’t “fully compatible” with Mountain Lion, as Shirt Pocket notes in its announcement blog post that it couldn’t complete work for supporting the automatic mounting of local volumes in time for this release. SuperDuper 2.7 requires Mac OS X 10.4.11 or later (which means it still supports both Intel- and Power PC-based Macs). (Free for basic functionality, $27.95 for additional features, free update, 3.2 MB)
Copy Disk Image as Folder
When you open a .dmg file, a disk image is mounted. You are then generally supposed to copy the contents of that disk image to your hard drive (to your Desktop, your Applications folder, or wherever). But what if you want to copy the whole disk image, including all its contents, as a folder? Hold the Option key, and drag the "proxy icon" in the title bar of the disk image window to the destination in the Finder.
