Apple have released a developer beta of their upcoming operating system named macOS High Sierra, which will be macOS 10.13. The name High Sierra continues on with their California landmarks with the name after a scenic CA region, it should be publicly available between September to November.

Lucklily for most the new macOS High Sierra 10.13 will run on the same machines as its predecessor macOS Sierra 10.12. Apple had already dropped support for any models pre late 2009 for MacBook and iMac. And anything pre 2010 for MacBook Air, MacBook Pro, Mac Mini and Mac Pro.

Now increase the size of Memory for macOS High Sierra from 2 GB to 4 GB for better installation performance. Step #1: Extract macOS High Sierra Image. Once you have downloaded the macOS High Sierra.

You’ll still require a 64bit Intel processor, 8GBs of free disk space – if upgrading, as appose to clean install min plus at least 2GB of RAM.

The Macs that will run macOS Sierra

• iMac – all models from late 2009, iMac 10,1 – 17,1
• MacBook & MacBook Retina – all models from late 2009, MacBook 6,1 – 9,1
• MacBook Pro – all models from 2010, MacBook Pro 7,1 – 11,5
• MacBookAir – all models from 2010, MacBook Air 3,1 – 7,2
• Mac Mini – all models from 2010, Mac Mini 4,1 – 7,1
• Mac Pro – all models from 2010, Mac Pro 5,1 – 6,1

Which means most devices made prior to 2008 won’t be able to run it.

The ones that fall short…

– macOS High Sierra won’t runon –

• iMac 4,1 – 9,1
• MacBook 1,1 – 5,1
• MacBook Pro 1,1 – 5,2
• MacBookAir 1,1 – 2,1
• Mac Mini 1,1 – 3,1
• Mac Pro 1,1 – 4,1
• Xserve 1,1 – 3,1

Make your Mac invincible

The day has come, High Sierra is available for upgrade. In case you were hesitant about whether you should rush to do it, don’t be. It’s a solid improvement with a whole bunch of new features. The new Apple File System and the end of autoplaying videos in Safari browser alone are worth it. You can check our separate entry on High Sierra features if you want. So, let us proceed to the macOS update and preparation.

Important notice: Apple has recently pulled down macOS Sierra installer from the Mac App Store. This means that if you decide to upgrade now, the only OS you’ll be able to go back to is El Capitan. We kindly advise you to consider this before upgrading and make sure you’ll be willing to keep High Sierra for the next year.

Can your Mac update macOS this time?

Here are all the Mac models that are fit to run the latest OS 10.13.

Does your Mac have enough space and RAM?

Hardware requirements haven’t changed since last time, so it’s still like this:

A few things before you install new macOS 10.13 High Sierra

To check your available disk space, click on the Apple icon in the top left corner of your screen and choose About this Mac.

Find the Storage tab and see how much free space you have. If it’s low, get a Mac cleaner to free up some space. Let's talk about it in detail.

Clean up your Mac

Mac software update always works better on a clean computer, without old cache files, leftovers, and random system junk. So before you go get yourself that new High Sierra download and run it, make sure you have a clean Mac. There’s a great app for that, CleanMyMac. It deals with all kinds of system and hard drive trash in minutes, so you don’t have to lift a finger looking for junk manually.

Don’t forget to back up important data

Another step that needs to be remembered at all times: back up. Back it all up.

Upgrades are mostly safe and stable but you really don’t want to be that one accidental glitch in the system where your files get corrupted. So a proper backup is a must. You can get a powerful software for the job, Get Backup Pro. It’s faster and more secure than the native Time Machine.

Check Hard Disk for Errors, Health, Bad Sectors before upgrade macOS

You might also want to check your disk for errors before upgrading.

You can do it with Disk Utility app:

1. Simply open Disk Utility app
2. Click on First Aid and run it. It will check your startup disk for possible errors and fix them if it finds anything.

And run disk bad sector checking with Disk Drill app:

Should you upgrade or get a clean install?

First, you probably want to know what’s the difference between the two. Upgrade is a simple installation of a new system over the old one, where the core software gets upgraded while your files and system preferences remain intact.

A clean install, on the other hand, is a more radical way of upgrade that removes all your files on the hard drive. Now, why would you want that? Well, your system could’ve been misbehaving lately, your hard drive overloaded and you don’t feel like cleaning it, or you just want that feeling of a brand new Mac again. In this case you’ll have to upload the files you still need in the cloud or save them on another drive.

How to download macOS High Sierra

This is pretty easy, even though not always fast. Your latest macOS download is on the Mac App Store.

So, follow these steps to download and update macOS:

1. Make sure you have a fast and stable WiFi connection. Don’t use public networks in cafes/hotels for upgrades, they can be of poor quality and interrupt the process.
2. Open the App Store app on your Mac.
3. Fin the last tab in the top menu, Updates.
4. Click it.
5. One of the updates is macOS High Sierra.
6. Click Update.
7. Your download has started.
8. High Sierra will update automatically when downloaded.
