As with past years, Apple's WWDC 2016 keynote showcased the upcoming updates to Apple's operating systems and developer tools. It's hard to believe that iOS is now on its tenth major version, which put Apple in an interesting position since their desktop operating system has been called OS X for many years now. Given that Apple's other operating systems are named iOS, watchOS, and tvOS, the name OS X has become a bit of an outlier. This year's release comes with a new name in the typical manner that OS X releases each had a specific name, but also a new name for the operating system itself. The 2016 version of Apple's operating system for Macs is named macOS Sierra.

While macOS adopts a new name, it retains the existing versioning system, with macOS Sierra being version 10.12. This makes sense when you consider the progression from Mac OS 9 to Mac OS X, which then treated each release as a point update on top of ten and only dropped the Mac in the name in 2012. This kind of versioning is somewhat awkward, and will be more so when it gets to the point where the OS is version 10.20. It will be interesting to see if the next truly large update to macOS brings it to major version eleven, and it could be that Apple plans to keep it in sync with iOS with a new major version number each year, but only time will tell.

Like all updates to macOS, Sierra comes with a number of new features. With the bulk of Apple's device sales being mobile devices, there have been a number of features in recent versions of macOS that work to leverage how devices running macOS, iOS, and watchOS can work together. Having cloud sync across devices is one thing, but building and properly executing Apple's continuity features really requires control over the hardware and software stacks across all devices. Unfortunately it's difficult to test these features during Apple's beta period, but that just gives Apple's users things to look forward to later in the year.

More important than new features is whether or not a Mac can even be upgraded to macOS Sierra from OS X El Capitan. Apple has announced the compatibility list for Sierra, and there are some older Macs that have dropped off the list. I've put together a chart comparing the compatibility of Macs with El Captain and compatibility with Sierra.

  OS X El Capitan macOS Sierra
MacBook Pro Mid 2007 and newer 2010 and newer
MacBook Air Late 2008 and newer 2010 and newer
Old MacBook Late 2008 aluminum and newer Late 2009 and newer
New MacBook 2015 and newer
iMac Mid 2007 and newer Late 2009 and newer
Mac Mini Early 2009 and newer 2010 and newer
Mac Pro Early 2008 and newer 2010 and newer

As you can see, it looks like Apple has put the cutoff point right around the start of this decade. The old MacBook and iMac that released in late 2009 make the cut, but everything else has to be a model from 2010. The uniformity of the cutoff makes it fairly likely that this was a somewhat arbitary decision, although it's difficult to say exactly how many older Macs could have been put on the list because Apple offers many SKUs and CTO options that could make one version of an older Mac fast enough and another from the same line too slow. In any case, the easy rule with Sierra is that if your Mac is from before 2010 it's probably not supported, and if you're in that group you're probably overdue for an upgrade anyway.

With Apple having just released their public beta of macOS Sierra, it's worth going over the major features that are currently available for users to try before the OS is officially launched later this year. Features like Auto Unlock and Apple Pay on the web can't really be shown right now, but it is possible to show other features that work between iOS and macOS devices like the additions to Messages and Photos. While I think the smaller and more subtle features in software updates can be some of the most useful, It's probably best to start off with the biggest feature in Sierra, which is Siri coming to the Mac.

    I hope y;ire just kidding. If you look at the percentage of Apple stuff here, y;I'll se that it is right where it should be. I don't complain about all the Microsoft stuff, or all the Google stuff. I don't complain about all the reviews of obscure things done here that almost no one will every buy.

    The only time I've every been annoyed with that is when it took months for the full review of an Apple product to come out, when the preview review came out right away. But this is a big thing, believe it or not, and a lot of us ARE interested.

    So go read other articles posted then. You whiners are insufferable

    I just came from the front page. 3 links to Apple related stories, 25 to non Apple related stories. I'm pretty sure there were other phone reviews there too.

    So where's the GTX1080 in depth look and review? Any article on the GTX1070? 1080 is nearing 2 months at this point, at least it got a preview. Nothing for the GTX1070 whatsoever, and it's been 1 month too. Are you guys just going to ignore them like you guys have the GTX950/960? Where reviews were promised but never delivered?

    How about phones, where's the HTC10 review?

    Come on what the fuck Anandtech? Release day reviews?

    Let me guess, by day you're a motivational speech writer?

    11 AT-length pages of architecture/features are now done. So it's nearing completion.
  • RaichuPls - Wednesday, July 13, 2016 - link

    Alright man, thanks for replying. Hopefully I've got something to look forward to.
  • Impulses - Wednesday, July 13, 2016 - link

    Now you've done it Ryan, prepare to be tracked and measured on a page/day metric until the review is out...
  • fanofanand - Wednesday, July 13, 2016 - link

    Not true, he told us a week ago it was almost finished, that cat was already out of the bag.

    People either have warmed memories, haven't been around long enough, or just choose to ignore that late but often the most detailed has always been the mantra here, Anand or not.

    Other reviews may be out sooner but 95% of them don't go too deep.
