Some of them find difficult to perform regular disk management activities on Apple hard disk drives including partitioning the disk, creating, resizing and deleting a partition. But this makeover didn’t go well for a handful of Mac users. That’s it, enjoy and let me know how it went.Disk Utility got a facelift with the launch of OS X El Capitan.
