Some of the key points are: #1 OS X Finder ? damages the system, can't copy files reliably, can't do useful things it ought to do at all, hides key files, rife with bugs.

#2 Disk utility ? under some conditions, destroys arbitrary numbers of volumes, no real upgrade for years, took two minor releases to fix RAID support

#3 iCloud ? a organization-destroying bug-ridden unreliable disaster

#4 File system ? continued use of HFS Plus instead of robust ZFS. ?

If these indictments are seen as the complaints of demanding user, Harris says in less than 5 years they can be complaints of users even with lesser demands.

With all the money and expertise Apple has, it will take sustained effort and attention from top management, including Ive, to fix these problems on OS X and iOS. The particular stress in placed on Ive because he's been given significant software responsibility by Tim Cook. Harris says he included iOS too, since in 10 years it will be handling workloads of 100 times greater than it does today. Fix OS X and then migrate that technology to iOS as needed.

Mac software engineering knew ZFS was a good thing seven years ago, but has since stuck with HFS+. OS X is overdue for a fundamental overhaul and a re-commitment to excellence in software engineering.

(ZFS is a combined file system and logical volume manager designed by Sun Microsystems. The features of ZFS include protection against data corruption, support for high storage capacities, integration of the concepts of filesystem and volume management, snapshots and copy-on-write clones, continuous integrity checking and automatic repair)
