The sworn-by advice for years by experienced OS X users and Apple alike was to run Disk Utility and click Repair Permissions as the first step in troubleshooting something gone wrong: a printer driver failing, an app’s strange behavior, a weird interface glitch? Repair permissions!

Each mountable partition can appear as a separate disk icon in the Finder these are often called volumes and, via Terminal, can be found in /Volumes directory.īefore digging into how to use the new setup, it’s important to note a key omission: Verify Permissions and Repair Permissions are gone. A physical drive has logical divisions, called partitions, that allow different formatting parameters on the same physical drive. You format a drive to make its raw storage compatible with one or more operating systems.

It has most of the same features, but the interaction and display is entirely different.Įxpert users may be frustrated and resort to learning the ins and outs of diskutil, the command-line utility available via Terminal that’s always had more switches and controls than the graphical Disk Utility.īut for many users who need to make quick and rare trips to this software, it could be an improvement: less frightening, easy to use, and harder to make mistakes. With El Capitan, Apple has done more than slap on a fresh coat of paint. The hoary app used for creating logical divisions in disks, applying first aid to ones with data damage, and repairing permissions seemed a thing from a previous age. Disk Utility hadn’t changed much over the years.
