The classic OS X 10.12, or rather macOS upgrade, introduced tons of features anyone would still want on their Mac. Why? Because, it's well-tested and secure. Now we'll take a quick look at the legendary macOS Sierra upgrade. (In case you want to upgrade your Mac to macOS 10.13 High Sierra, check out this guide.)

Say hello to macOS 10.13 High Sierra, the new operating system for Mac desktops and notebooks that brings some impressive under-the-hood refinements. If you were expecting some big overhauls, chances are you’ll be disappointed at a first view.

Interestingly, it first brought Siri to your Mac. This is great news for everyone who’s already used to her help on iOS. Then, there’s Watch unlocking for Mac, there’s one-click Apple Pay, tabs in apps, and cross-device copypasting. Just to name a few.

So, if you were on the fence about upgrading to Sierra, and in fact, any newer OS, go right ahead. Your Mac deserves a refreshment.

Does order matter when you upgrade macOS?

If your current operating system is OS X Lion (10.7), you can skip a few versions, and upgrade directly to macOS High Sierra. To upgrade to Sierra from, say, Mavericks, you’ll have to consequently upgrade to Yosemite and then to El Capitan first.

Check Your macOS for Sierra Compatibility

These OS versions can upgrade to Sierra:

  • OS X Mountain Lion v10.8 or Lion
  • OS X Mavericks v10.9
  • OS X Yosemite v10.10
  • OS X El Capitan v10.11

Here’s how to find out which OS version you’re running now:

Update Mac Os 10.12 To 10.13
  1. Click Apple icon in the top left corner.
  2. Choose About this Mac.
  3. There you have it, in capital letters.

Memory (RAM): 2 GB (preferably 4 GB)
Sierra is pretty lightweight, so you only need 2 GB of RAM to upgrade. Cool, eh?

Disk space: 8 GB of free space on drive.
In the same About this Mac menu select 'Storage' tab. In front of the multi-colored bar, you will see the phrase, 'X.XX GB free out of XX.XX GB.' If you don't have at least 8 GB of free space, you should delete some old files.

Before you update macOS, don’t forget to:

Clean up your Mac

How to update macos 10.12.6 to 10.13

This is essential if you want a fast and effortless update, and glitchless work of your new macOS. And it’s also pretty easy. To give your Mac a cleanup, you need to get rid of system junk, uninstall extra apps, and clean some old caches. If that sounds like a lot of work, you can get a Mac cleaner like CleanMyMac for the job.

How to update your Mac: Clean it up first

  1. Launch it.
  2. Hit Scan to find all the extra files you can delete.
  3. Press Run.

As you can see, I have 8.56 GB worth of caches, obsolete language files, broken downloads. You'll feel great getting rid of them.
That will give your Mac a basic system cleanup, but CleanMyMac is going to come in handy after the update as well. It monitors your Mac’s health, helps you speed up the system and remove unnecessary apps (Trashing doesn’t fully uninstall apps, by the way).

Update

Back up your Mac

This is basic common sense before any Mac software update you’d like to undertake. Why? Well, because sometimes updates happen less smoothly than you’d like them to. To make sure you have all your information and files saved up neatly, you need a backup. To back up your Mac, you need to activate Time Machine.

  • Open your Applications folder.
  • Choose Time Machine.
  • 'Select Backup Disk…'
    Note: You may need to first choose to 'Set Up Time Machine.'
  • Choose where you'd like to store your backup.
  • Both an external drive or an Airport Time Capsule fit.
  • Switch the toggle on the left, from 'OFF' to 'ON.' Right beneath the name of your storage device, you'll see 'Oldest backup,' 'Latest backup,' and 'Next backup' — Your backup will begin within 5 minutes. To speed it up, click the arrow clock icon next to the Date & Time at the top-right of the menu bar and select 'Back Up Now.'

How to download macOS Sierra (or newer macOS) and install it

macOS Sierra is increasingly becoming a relic. Since 2020, the newest available macOS version is Big Sur. But it all comes down to hardware. Your Mac can only upgrade to the latest version its hardware can support. If your Mac is from around 2012 it can update as high up as to macOS Catalina. If your Mac is from 2010 or older, its limit is macOS High Sierra.

To download any new macOS and install it you’ll need to do the next:
1. Open System Preferences... in the  Apple menu.
2. Click on Software Updates.
On top of the list you'll see the latest macOS version your Mac can download. In our case, it's macOS Big Sur.

Another way to do it is via the Mac App Store.

  1. Open App Store.
  2. Click the Updates tab.
  3. You’ll see macOS updates available for your Mac.
  4. Click Update.
Update Mac Os 10.12 To 10.13

Wait for macOS download and installation. Your Mac will restart when it’s done.

Now you have a new OS.
For historic interest, this is how macOS Sierra looked back then when it was still available in the Mac App Store. Now, it can't be found there anymore.

Download macOS installers directly from Apple

For users of past operating systems Apple created a handy a list of macOS installers. They go as far back as to macOS Yosemite. The first 3 of them will open and start the update process automatically.

  • macOS High Sierra 10.13
    The 3 following installers will download macOS as a disk image (.dmg) After you unpack it, the macOS updater app will appear in your Applications.

We hope this guide has been of use, and don’t forget to clean up your Mac and back it up before you get the classic macOS! Cheers.

Some entries may appear out of chronological order (i.e. 10.5 is shown on Oct 26, but above Nov 14 for 10.4.11). This is to keep the version numbers in the proper order, even when an older OS received an update after a major new release came out. This has happened a few times over the years.

Upgrade From Macos 10.12 To 10.13

Some random notes, updated from the original post:

  • Starting with the Public Beta and up through 11.6, there have been 154 macOS releases, both major and minor. This figure includes the one odd macOS X release: 10.2.7. This version was only for the then-new PowerMac G5 and the flat panel iMac G4, and was never generally released.
  • As of September 13th, 2021 (11.6's release date), it's been 7,670 days since the Public Beta was released. So on average, we've seen some sort of update every 50.1 days.
  • The shortest time period between any two releases is six days, which is how quickly the 10.15.5 Supplemental Update 1 came out after the 10.15.5 release.
  • The longest time period between any two minor releases is 165 days, which was how long we waited for the 10.4.9 update. (Tecnically, it's actually the 192 day interval between the Mac OS X Public Beta and version 10.0, but I'm counting from the official 10.0 release.)
  • The smallest update was 10.3.1, at only 1.5MB. The largest (non-combo, non-main OS release) update was 10.15.1 at 5.3GB.
  • The '???' entry for Size on a given release indicates I was unable to find the size. Feel free to contact me if you can help replace any of the '???' entries.

And now, gratuitous graphics…
