Colorful disk usage info screen in OS X LionOctober 22nd, 2011
OS X Lion has absorbed some user interface idea from iOS. Disk storage info is one example. In OS X Lion, the system info for storage now lists usage grouped by Audio, Movies, Photos, Apps, Backups and Other. To access this info, from the system menu, select “About This Mac”. Click on the button “More Info…” and select the tab “Storage”.
