* Complete Guide on How to Upgrade to macOS Sierra

I want to download macOS Sierra from the App Store to create a bootable USB stick (according to Apples web page). However, the App Store tells me that I have installed it and only shows me an 'open' button. There is no Install macOS Sierra app in the applications folder. What to Do if Your Mac Can’t Run macOS Sierra. Posted on December 15th, 2016 by Joshua Long. Note: Although this article was written for macOS Sierra (10.12), much of it still applies to macOS High Sierra (10.13) which was released in September 2017. Mar 19, 2017  When I try to download Sierra, I get the following message: 'This version of mac OS 10.12 cannot be installed on this computer'. 'This version of Mac OS X cannot be installed on this computer' probably means that your system definition is that of a Mac that fails to.

1. Back up Mac Before El Capitan to Sierra Update

Before you download and upgrade, backing up Mac is the first essential thing to do. Backup helps you get access to all the files, including photos, videos, music etc., and especially useful if any macOS Sierra upgrade problems occur. So, remember to back up Mac before updating to macOS Sierra. You can use Time Machine to backup full Mac file, or iCloud to backup the music, photos, calendars, etc. Or alternatively, simiply backup what you think important and make enough room for macOS Sierra upgrade and download with other tools like MacX MediaTrans.

If you feel it's difficult to understand the tutorial of downloading and upgrading or too much trouble, go to Apple store for help. If you have problems, like macOS 10.12 can't installed on Mac computer, or macOS Sierra stuck installing etc, get the fix below.

3. macOS Sierra Upgrade Hardware Requirements

Not all Mac have the luck to upgrade to macOS Sierra. Read macOS Sierra hardware requirements below to check whether to upgrade or not.

MacBook Pro (2010 and later) MacBook Air (2010 and later)
Mac Mini (2010 and later) Mac Pro (2010 and later)
MacBook (Late 2009 and later) iMac (Late 2009 and later)

If you don't know if your Mac's compatiblity, you can check the model make and model year by clicking the 'About This Mac' in the upper left corner.

Although Apple makes new software updates available to as many older devices as possible, there are always some reasons why it may not be in your best interest to install the latest and greatest right on day-one, even if your Mac is compatible. With macOS Catalina just around the corner, take a moment to consider whether you should make the leap right away or wait a few days (or even weeks) to update your Mac.

Is my Mac compatible?

If you have the following model of Mac, you can download and install macOS Catalina:

• MacBook (Early 2015 or newer)
• MacBook Air (Mid 2012 or newer)
• MacBook Pro (Mid 2012 or newer)
• Mac mini (Late 2012 or newer)
• iMac (Late 2012 or newer)
• iMac Pro (2017)
• Mac Pro (Late 2013, plus mid-2010 and mid-2012 models with recommended Metal-capable GPU)

If your Mac is older than any of the models listed above, it isn't compatible with macOS Catalina.

What about other minimum requirements?

Are you postponing updating your iPad to iPadOS 13, or are using an iPad that isn't compatible with iPadOS 13? You won't be able to use Sidecar. It requires both macOS Catalina and iPadOS 13. iPadOS 13 is supported on the following devices:

• 12.9-inch iPad Pro
• 11-inch iPad Pro
• 10.5-inch iPad Pro
• 9.7-inch iPad Pro
• iPad (7th generation), iPad (6th generation), and iPad (5th generation)
• iPad mini (5th generation)
• iPad mini 4
• iPad Air (3rd generation)
• iPad Air 2

To take advantage of 4K streaming movies and TV shows in the TV app you'll need a Mac laptop or desktop that supports 4K resolution. According to Apple's Catalina features page:

4K, 4K HDR, 4K Dolby Vision, Dolby Atmos, and HDR10 content is available on all Mac models introduced in 2018 or later with 4K-resolution screens.

To hear Dolby Atmos audio in the TV app, you'll need a Mac notebook from 2018 or later

Do you meet the requirements to use all of macOS Catalina's new features? Are the featrues your Mac doesn't support deal breakers for you? You may want to think about postponing updating a little longer or upgrading your Mac.

What about my iTunes Library?

In macOS Catalina, Apple has redesigned the way we listen to music and podcasts, watch movies, and read books. Similar to how the iPhone works, these features are broken out into individual apps instead of a singular iTunes app.

What does this mean for your well-currated iTunes Library of songs you've burned from CD and meticulously tagged and added customized metadata? It should mean absolutely nothing. iTunes isn't being deleted. It's simply being broken out into separate apps. Your iTunes Library will stay intact. You'll just find it in the new Music app.

If, however, you are concerned with potentially losing all that data you've added manually, I highly recommend postponing updating until the coast is clear. I didn't have any issues getting my entire iTunes Library in the beta of macOS Catalina, but I don't input my own tags and other information, so I don't have first-hand experience with it's migration. Once Catalina is available publicly and more people have installed it, we'll have a bigger audience to know for sure how well metadata syncs.

If you want to take the risk and update on launch day, just be sure to back up your iTunes Library so if something happens, you can get it all back.

What about unsigned third-party apps?

Security gets a little more secure in macOS Catalina. You'll get more notifications about apps accessing data and permission requests to use them. Activation Lock makes it harder for someone else to wipe your data. It also adds some stricter security measures that may make Gatekeeper think apps you've previously given permission to are not secure enough for your Mac. From Apple's Catalina features page:

macOS Catalina runs in its own read-only volume, so it's separate from all other data on your Mac, and nothing can accidentally overwrite your system files. And Gatekeeper ensures that new apps you install have been checked for known security issues before you run them, so you're always using good software.

If you are using apps that, in a former OS (High Sierra or older), you were able to download 'from anywhere,' you should find out from the developer whether their apps are compatible with macOS Catalina before you decide to update.

I'm ready to try it out, but what if I don't like it?

Upgrading to a new software system, especially on a computer, can be a big upheaval that causes stress and confusion. You might be excited about macOS Catalina after reading about everything it can do, but quickly decide that it's not right for you.

The first, and most important thing you should do before upgrading to macOS Catalina (or updating any software, no matter how small), is to back up your Mac.

Next, it is not a bad idea to think about partitioning your Mac so you can install macOS Catalina in tandem with your current Mac operating system. That way, you can get used to the changes while still having access to what you are familiar with. It will also make it easier to simply delete the software if you know you don't want to use Catalina at all.

If you've downloaded macOS Catalina on your main hard drive, you're not out of luck. You can always downgrade back to your previous operating system.

OK. I'm just going to go for it!

Wait!

It's not always such a good idea to download a huge update on Day One. There are a number of factors that can give you a negative experience right out of the gate, which might leave a bad taste in your mouth.

Media Player Download available for some devices. Vlc for mac free download full version.

Hundreds (or even thousands) of people will hit the download button the exact moment they hear that macOS Catalina is available to the public, which could put a strain on the servers and make it take a really long time for you to complete the process.

Why Can't I Download Mac Os Sierra

With changes in macOS Catalina, it also means that some third-party apps will need to be updated for compatibility. Not all developers will have their updates ready right away. If there are any apps that you just can't live without, you might be forced to .. well .. live without until they are updated. The best way to see if your must-have apps are going to be ready for macOS Catalina is to visit the companies' websites or check their social media feeds.

Proceed with caution

If, after reading everything I suggested, you still think you are ready to upgrade to macOS Catalina, then, by all means, go for it! I've been using it for a couple of months now, and frankly, I love it. Just make sure you've got a current backup of your Mac, just in case something goes wrong.
