How to Prepare for and Install macOS Mojave

Prepare for and install macOS Mojave

Now that MacOS Mojave is available to download for all Mac users, you may be interested in updating to the latest and greatest Mac system software release. But before diving in with the installation, it’s often a good idea to prepare a Mac for a major system software update.

This article will go through a handful of simple tips that can help to prepare a Mac for the MacOS Mojave update.

Update now, or wait?

Many Mac users are going to be excited to install MacOS Mojave right away, and features like Dark Mode will be a particularly strong pull to many. While there’s certainly nothing wrong with updating immediately, and you’ll be amongst the first users to experience all the new features macOS Mojave has to offer, others might want to take a more cautious approach and wait a little while before installing any new system software.

Some Mac users will wait for a later point release update to come along before installing a new system software version, with the idea being that the first (or several) point releases will include bug fixes and enhancements that could improve the overall experience. Maybe that could be macOS 10.14.1, macOS 10.14.2, macOS 10.14.3, or even a later version. Or maybe they need to wait for a particularly important third party app to support the latest macOS release. Maybe you decide to skip Mojave entirely because you’re thrilled with Sierra or El Capitan or whatever you’re currently running, that’s OK too. It’s your computer, do what works best for you!

Check Compatibility

MacOS Mojave has some stricter system requirements than prior versions of Mac system software. The list of Macs compatible with MacOS Mojave is as follows:

  • MacBook – early 2015 or later
  • MacBook Air – mid 2012 or later
  • MacBook Pro – mid 2012 or later
  • Mac Mini – late 2012 or later
  • iMac – late 2012 or later
  • iMac Pro
  • Mac Pro – late 2013 or later
  • Mac Pro – mid 2010 or mid 2012 models with recommended Metal-capable graphics processor, including MSI Gaming Radeon RX 560 and Sapphire Radeon PULSE RX 580

Aside from having a Mac which supports the MacOS Mojave release, it’s also a good idea etc have around 20 GB (or more) of free disk space available to install the software update.

Backup the Mac

Having a full backup of your Mac and all important data is critical, especially before installing a major new system software update.

Don’t skip the backup process. A failure to complete a full backup of the Mac could lead to irreversible and permanent data loss if something goes awry during the software update process. Having backups can prevent that from happening.

It’s very easy to use Time Machine to backup a Mac as discussed here. You can also use another backup service of your choosing, as long as you are backing up your Mac and the important data on it.

Consider App Compatibility & Update Apps

Most Mac apps will work fine in macOS Mojave, and most active software developers will be updating their apps to fully support macOS Mojave if they have not done so already. Nonetheless it’s a good idea to consider app compatibility, and to update apps so that they work in the latest macOS Mojave release.

If you have a single app that is absolutely mission critical to your workflow and productivity, you might want to investigate that app specifically for compatibility with macOS Mojave before installing the system software update. Often the easiest way to do that is usually by going to the app developers website, support section, or contact the app developer directly via customer service to see if there are any special notes about macOS Mojave compatibility.

Often simply going to the Mac App Store “Updates” tab and installing all available app updates will get the job done too, and over the weeks after updating to macOS Mojave it’s a good idea to return to the Updates section of the App Store to install them as they come in too.

Ready? Install the MacOS Mojave Update

So you’ve determined you have a compatible Mac, you updated your apps, and you backed up the entire computer so that your data is safe… now you’re ready to install macOS Mojave!

The final version of MacOS Mojave is available to download now, and installing the update is quite simple:

  1. Backup the Mac if you have not done so already
  2. Download the MacOS Mojave installer app from the Mac App Store here
  3. The MacOS Mojave installer will launch automatically*
  4. Install macOS Mojave

  5. Run through the installer and update to MacOS Mojave, the Mac will reboot automatically when complete

That’s it! Updating to macOS Mojave is simple and relatively quick, if you already have the installer downloaded it’s about 45 minutes on the Macs I have tested the process on.

* If you wish to make a bootable USB installer for macOS Mojave for using to install on other Macs or as a boot drive, quit out of the installer first and then proceed with that process. If you run the installer and install MacOS Mojave, the installer will delete itself from your Applications folder when complete.
