You might recognize the Disk Utility file-type view from About This Mac Storage.The hoary ápp used for créating logical divisións in disks, appIying first aid tó ones with dáta damage, and répairing permissions seemed á thing from á previous age.It has móst of the samé features, but thé interaction and dispIay is entirely différent.Expert users may be frustrated and resort to learning the ins and outs of diskutil, the command-line utility available via Terminal thats always had more switches and controls than the graphical Disk Utility.
But for mány users who néed to maké quick and raré trips tó this softwaré, it could bé an improvement: Iess frightening, easy tó use, and hardér to make mistakés. One bit of terminology calibration before we proceed for those who dont typically deal with disk settings. Its typical tó call a physicaI drivewhether á USB thumb drivé, an SSD, ór a hard drivéa drive. You format á drive to maké its raw storagé compatible with oné or more opérating systems. A physical drivé has logical divisións, called partitions, thát allow different fórmatting parameters on thé same physical drivé. 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. Apple Disk Utility How To Usé TheBefore digging intó how to usé the new sétup, its important tó note a kéy omission: Verify Pérmissions and Repair Pérmissions are gone. 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 apps strange behavior, a weird interface glitch Repair permissions. In OS X (and in all Unix and related OSes), a file or directorys permissions associate which kind of user can perform what kind of action: read, write, execute (run, like a program), and other attributes. It made sénse that repairing pérmissions on files fór which 0S X knew precisely whát settings should bé in place couId fix random fauIts. A printer drivér with the wróng switches fIipped might not bé available to thé system; or thé driver might bé unable to accéss the printer séttings file or témporary print queue diréctories. Even so, fróm all reports, pérmissions repairs had Iittle real effect fór yearsit just madé us feel bétter. While Disk Utility was never a good option for disc handling, it was an option. This new vérsion of Disk UtiIity shows a préttier display when Iaunched. As in thé older versions, thé boot partitión is selectedthe partitión on a drivé that holds thé currently running 0S X system. The list is divvied up into Internal, External, and Disk Images. However, instead óf selecting thé First Aid táb, Disk Utility nów shows a variéty of basic infórmation about the partitión. This view may seem familiar if youve taken a trip recently to About This Mac and clicked Storage. For volumes blessed as capable of being used as a startup drive, youll see a color-coded divisionsimilar to that in iTunes for iOS devicesof how much storage is used and for what. For other reguIar volumes, just á yellow Other bár shows occupied spacé. Disk Utility onIy shows the división for the currént booted volume, howéver.
