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.
