Common issues (and solutions) related to Mac OS X 10.13 update. Failed to download macOS High Sierra Package. This is one of the initial issues faced by users while upgrading to Mac OS X 10.13. Needless to say, it usually occurs due to an unstable internet connection or when Apple's server is busy. Hi I have recently purchased an iMac 27 – inch and I cannot add microsoft office onto it. According to your list of latest OS I can have is already installed 10.13.6 (late 2011 model). Please help I need microsoft office. Download & Install MacOS 10.12.4 Update. The easiest way to download and install the latest Mac OS release is through Software Update: Back up your Mac before beginning. Pull down the Apple menu and choose “App Store” Go to the “Updates” tab and choose to download and install “macOS Sierra 10.12.4” update.
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.
As with the previous versions, macOS Sierra is available for a limited list of Mac models.
Here are the models of Macs that are compatible with macOS 10.12 and can upgrade to Sierra:
|MacBook Pro||MacBook Air||Mac mini|
|Mid 2010 or newer||Late 2010 or newer||Mid 2010 or newer|
|Mid 2010 or newer||Late 2009 or newer||Late 2009 or newer|
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.
These OS versions can upgrade to Sierra:
Here’s how to find out which OS version you’re running now:
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
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.
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).
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.
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.
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.
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.
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.
