Apple rebrands OS X as macOS, announces Sierra with Siri, plus focus on Continuity & iCloud
Apple has announced it will rebrand its OS X platform as macOS with an update coming later this year, dubbed Sierra, with an emphasis on syncing data and settings through the cloud, and the debut of Siri on the Mac.

macOS Sierra was unveiled by software chief Craig Federighi at Apple's annual Worldwide Developers Conference on Monday. Siri on the Mac can be used for searching, messaging, and obtaining information such as movie times.
In an onstage demonstration, Federighi showed how search results obtained through Siri can be dragged directly from its window into another app.
The new OS will also focus on making files and settings available across devices when it launches to the public as a free update later this year. Desktop files will also be synced in iCloud, allowing the data to be retrieved from another computer or an iOS device. To clear up space, Sierra will be able to move old files to iCloud automatically.

Among its changes, macOS Sierra will give users the ability to bypass secure login on their Mac if they are wearing a securely unlocked Apple Watch, through a feature called Auto Unlock.
Apple Pay is also coming to iCloud, allowing users to authenticate purchases in a browser via a nearby iPhone or Apple Watch, thanks to Continuity.

The macOS Sierra update will also introduce cross-platform clipboard syncing, letting users copy content from one device and then paste on another.
iOS' Picture in Picture feature will also be coming to the Mac, allowing users to quickly push a video to a corner of the screen while they accomplish other tasks.
Sierra is available to developers starting today. A public beta will launch in July, and the free update will officially debut this fall.

Desktop in the cloud. Great. I keep something like 100 gigs there, so that won’t work. Neither will Sierra on my computer, so I guess that’s okay anyway.
Does Notification Center actually, you know, keep widgets in order now? I see it’s redesigned, but does it actually keep my stuff where I tell it to across boots/logins? That’d be nice…
LATE 2009 IMAC BUT NOT THE MAC PRO. I WASN’T UPSET BEFORE, BUT I AM NOW.
I’m going to hack this shit onto my computer. I don’t even care. This is what they get for making stuff that lasts for so long.
This is the end, beautiful friend. This is the end. My only friend, the end
Of our elaborate plans, the end. Of everything that stands, the end.
No safety or surprise, the end. I'll never look into your eyes...again.
Lost in a Roman...wilderness of pain. And all the children are insane.
Any word on compatible Macs?
macOS Sierra, meanwhile, is set to release in the fall as a free upgrade. According to Apple, the operating system will be compatible with late-2009 and later MacBook and iMac, as well as 2010 and later MacBook Air, MacBook Pro, Mac mini and MacPro.
Looks like that'll be it for my Early 2008 MacBook Pro.
I might look into hacking it to run on it, unless the compatibility list is only preliminary so far. Might be time for a new Mac, though. I've been able to run every version of OS X since 2008 impressively so far.
Late 2009 iMac and... MacBook Pro, I think it was, and then everything newer.
EDIT: I JUST REALIZED THAT THOSE 2009 MACHINES ARE VINTAGE. AND THEY STILL GET IT. Fuck’s sake.
All this seamless integration sounds great until you get into the corporate world.
but i doubt you even work in an industry like you describe, and are just coming up w/ chicken-little scenarios out of neurosis.

Sure, but if you do so, you should be able to at least disable some functionality on your devices, Mr. Nadella. ;-)
