Adrian Kingsley-Hughes, writing for ZDNet: "It just works." This is the phrase that Steve Jobs trotted out year after year to describe products or services that he was unveiling. Well, Steve is now long gone, and so it the ethos of "it just works." 2017 was a petty bad year for Apple software quality. Just over the past few weeks we seen both macOS and iOS hit by several high profile bugs. And what's worse is that the fixes that Apple pushed out -- in a rushed manner -- themselves caused problems. A serious -- and very stupid -- root bug was uncovered in macOS. The patch that Apple pushed out for the root bug broke file sharing for some. Updating macOS to 10.13.1 after installing the root patch rolled back the root bug patch. iOS 11 was hit by a date bug that caused devices to crash when an app generated a notification, forcing Apple to prematurely release iOS 11.2. iOS 11.2 contained a HomeKit bug that broke remote access for shared users. And this is just a selection of the bugs that users have had to contend with over the past few weeks. And it's not just been limited to the past few weeks. There's no such thing as perfect code, and sometimes high-profile security vulnerabilities can result in patches being pushed out that are not as well tested as they could be. But on the other hand, Apple isn't some budget hardware maker pushing stuff out on a shoestring and scrabbling for a razor-thin profit margin.
