It’s why there’s nothing else like a Mac. MacOS is the operating system that powers every Mac. It lets you do things you simply can’t with other computers.
That’s because it’s designed specifically for the hardware it runs on — and vice versa. MacOS comes with an entire suite of beautifully designed apps. It works hand in hand with iCloud to keep photos, documents, and other stuff up to date on all your devices.
It makes your Mac work like magic with your iPhone. And it’s been built from the ground up with privacy and security in mind. Continuity All your devices.
One seamless experience. Your Mac works with your other Apple devices in ways no other computer can. If you get a call on your iPhone, you can take it on your Mac. With Continuity Camera, you can use your iPhone to take a picture or scan a document nearby, and it will appear right on your Mac.
When you copy text or an image from one device, you can paste it into another with standard copy and paste commands. You can even unlock your Mac with your Apple Watch. No password typing required. Built-in Apps Apps as powerful and elegant as your Mac.
Because they’re designed for it. With every Mac, you get a collection of powerful apps. They’re the same apps you use on your iPhone or iPad, so they’ll feel instantly familiar. They all work with iCloud, so your schedule, contacts, and notes are always up to date everywhere. And because they’re native apps — not web apps in a browser — they take full advantage of the power of your Mac to deliver the fastest possible performance and more robust features. ICloud All your stuff.
On your Mac, and everywhere else you want it. Every Apple app uses iCloud — it’s the magic behind the seamless experience you have with all your Apple devices. So you always have your photos, videos, documents, email, notes, contacts, calendars, and more on whatever device you’re using. And any file you store in iCloud Drive can be shared with friends, family, and colleagues just by sending them a link. ICloud Drive also lets you access files from your Mac desktop and Documents folder on any iOS device.
It’s all done automatically. Just like that. Technology Advanced to the core.

Following the release of macOS High Sierra, Mac users that Apple is no longer listing previous operating system updates in a user's Purchased tab in the Mac App Store. Neither macOS Sierra nor macOS High Sierra show up in the Purchased list, suggesting the updates are no longer tied to an Apple ID account. Previous Mac software updates were linked to an Apple ID account and updating required an Apple ID and password, something that could be a hassle when a Mac changed ownership. An on reinstalling apps confirms that the change to remove macOS Sierra and High Sierra from the Purchased tab was intentional. 'macOS Sierra or later doesn't appear in the Purchased tab,' reads the document. In the case of macOS Sierra, the change means that there's no way for Mac users to download macOS Sierra should they want to downgrade from High Sierra for some reason. OS X El Capitan, OS X Yosemite, OS X Mavericks, and earlier updates are all tied to a user account and listed in the Mac App Store.
Apple has also made a link to the OS X El Capitan update available, but no similar support document is available for macOS Sierra. This is why people were complaining so much about OS X becoming download-only since Lion.
If I wanted to install an older OS, whether it'd be for compatibility or testing, I want to be able to download it, especially when I don't have the space for dozens of OS installers 'just in case'. I was still fine with the older OS X installers being redownloadable, and even purchasable when the next OS was already released, but since Yosemite you can't get Mavericks unless you already owned it and now you can't even download Sierra, even if you downloaded it previously. This makes it seem like Apple is heading towards the forced upgrades and downgrade lockout from iOS, and that seriously concerns me. This is why people were complaining so much about OS X becoming download-only since Lion.

It's still available, just hidden from users. Here's a direct link to Sierra http://osxapps.itunes.apple.com/apple-assets-us-std-000001/Purple62/v4/af/5f/9d/af5f9d8e-cf9c-8147-c51c-c3c1fececb99/jze225146329.pkg. I have downloaded every point update full installer since Lion.
Once the 10.x reaches the final point, I keep only that. I have never trusted Apple (or Microsoft) not to pull something like this, so I protect myself. Can everyone stop repeating this.
OK we get it, you were all really really clever and have a copy. Especially after 5 people have said the same thing.
And I'd love to see one of you still so excited, if you happen to lose said copy, only to realise you also then can't get another via downloading it again directly from Apple, just as other users here cannot now. This thread is about why Apple have completely removed it from download, without any previous notice or comment as to why, post-High Sierra's release. Rather than how clever you are in having a copy already. This is so depressing.
Apple, why do you fight your users like this? Being able to install older OS's is essential for many reasons, not least running old machines or older applications. First signing on iOS and now this move?! I have a mission critical business app on iOS which is 32 bit.
Yes it would be nice if it were updated to 64 bit but it's not going to happen in this case, yet it's the backbone of my business. So I'm stuck at iOS 10. And if I have to restore my phone from a backup I'm screwed:-/. Equally our desktop machines run a vastly complicated set of audio and video plugins. Just one of them not being compatible with high sierra means I can't load up older work. For professional work we need an option to maintain a system with an older OS. Please rethink your philosophy here.
These complaints are ridiculous. The only type of person who would want to install an older operating system is a power user. And if you're a power user, you'll have the knowledge to be able to save installers, or be able to find any previous version of macOS on the internet and verify its integrity. If you don't know how to do either of those things, you aren't the type of person who would need to install an older OS. No they are not ridiculous. Picture this: You are on tour with u2 running their IT and have an hd crash. You need to reinstall sierra in a hurry (not high sierra as it's incompatible with some plugins being used) on a brand new hd and reinstall all the plugins etc.
The machine originally shipped with el cap. You forgot to bring the installer or a complete clone hd with you (the latter in my experience don't work well incidentally).
So you need to redownload sierra. How do you do it? Search the torrents?!
