How to prepare your Mac for macOS Mojave 10.14

Apple is about to release the new version of its operating system for Mac, macOS Mojave, here's what to do before installing the OS on our device

After unveiling it in June, during WWDC 2018, Apple is releasing in these hours macOS Mojave 10.14, new major release for its desktop and laptop computers. Several new features await owners of a Mac compatible with macOS 10.14: from dark mode to dynamic wallpapers, through group video calls and increased online security with Safari.

Before updating your Mac to macoOS 10.14, however, there are some "preliminary" operations necessary to protect the computer and our data in case something goes wrong during the update. Although it happens very rarely, in fact, it could also happen that the Mac hangs in the middle of the update process, forcing us to reset the device.

Compatibility macOS 10.14 Mojave

First of all, let's check that our Mac is compatible with the list of devices chosen by Cupertino for the update to MacOS Mojave 10.14. Computers eligible to receive the update are these: early 2015 or later MacBooks; mid-2012 or later MacBook Airs; mid-2012 or later MacBook Pros; late 2012 or later Mac minis; late 2012 or later iMacs; all iMac Pro models and late 2013 Mac Pros, as well as mid-2010 or mid-2012 models with Metal-compatible graphics processors, including the MSI Gaming Radeon RX 560 and Sapphire Radeon PULSE RX 580.

Check storage space

If our Mac is on the list of Apple's devices that will receive the update, we must first verify that we have the necessary space in the computer's memory. The space needed to install macOS Mojave is about 20 GB. Even a couple of GB less might be enough. To find out how much space you have available on your Mac, go to the Apple menu, then About this Mac, and then click on Storage. And you'll know how much storage you still have available on your Mac.

Create a backup

As mentioned in some cases it's possible that during the upgrade some files, such as photos or videos, or some data of a specific application are deleted by accident. That's why before installing macOS Mojave 10.14 we need to make a backup. To save in the cloud or locally on an external hard drive our most important documents.

How to install macOS Mojave 10.14

When macOS Mojave will be released it can be downloaded directly from the App Store, but on Mac computers equipped with the latest version of OS X El Capitan or later versions the download will be done automatically. In practice when Apple will release the new version in the background the PC will download the file with the update and through a notification will ask us if we are ready to update our OS. If you don't want macOS Mojave to download automatically, go to System Preferences, click on App Store and uncheck "Download available updates in the background".
