Many of us have been grumbling quite publicly since iOS 7 and Mavericks shipped that the fit and finish we expect either on release or shortly afterwards for Mac OS X and iOS has slipped. That we spent a lot of time dealing with bugs or, if we write about Apple, teaching people how to avoid them or work around them. That software and OS problems, once they occur, are rarely fixed in part or full; features we need are removed rather than matured; and new features are added that aren’t fully baked.
Part of what makes these sorts of statements reasonable, though, is to enumerate the problems, whether they’re long-running or unique to Yosemite or iOS 8 (or to the last two releases of each system). Here’s a list of regularly recurring issues or fundamental problems I’ve seen supplemented by those provided by others.
