Sometime this summer, macOS Mojave will be made available to participants in the Apple Beta Software Program. Since the Beta Software Program is open to anyone who wishes to sign up, it’s easier to think of this as a public beta for anyone whose Mac meets the minimum requirements for using macOS Mojave.

The macOS public betas are very popular with a large number of Mac users anxious to put the latest Mac OS through its paces. To help you get the most out of the betas, the Rocket Yard is lending a helping hand with a collection of macOS Mojave guides.

To pique your interest, we started off with What’s New in macOS Mojave: A First Look at the Developer Beta.

The follow-up article described How to Get Your Mac Ready for the macOS Mojave Beta.

And that leaves this article, which covers how to perform the actual install of the macOS beta.

Developer or Public Beta of Mojave?
Apple developers already have access to the beta of Mojave, and since the public beta isn’t quite available yet, we’re going to base our install guide on the developer version, and then come back and update the guide for any changes that occur when the public beta is released. I don’t expect too much to change between the developer and public beta versions. The usual changes seen in past betas were primarily differences in file names, installer commands, or menu names; there’s rarely a dramatic difference in the actual install process. But be sure and check back; you never know what may happen between now and then.

How Many Ways Are There to Install the macOS Mojave Beta?
More than you might think, but we’re going to look at two primary methods: the upgrade install and the clean install. We’ll also take a look at installing the beta on Parallels, a popular virtual machine app.

  • Upgrade Install: The easiest of the install options. It will upgrade your current version of the macOS to the beta version of Mojave. It will also update all of your Apple apps to the beta Mojave versions, and may also update the document formats of some apps. Because the upgrade install of the beta is an all-or-nothing process, I recommend that you install the beta on a copy/clone of your current startup disk. This will leave your current system intact and usable for your normal daily tasks, and still allow you to test and try out the beta on a different drive, one that contains copies of all your apps and data.
  • Clean Install: This install process creates a pristine copy of the macOS Mojave beta on a target drive. It can completely erase the destination volume and then install a fresh copy of the Mojave beta. I don’t recommend using this install method on your Mac’s normal startup drive since you would lose all your current data. Using the clean install method on an empty external drive is a better option.

Back Up, Please
Before using any of the install methods outlined here, be sure to start the process by making sure you have a current backup of your startup drive, as well as any other drives that contain important information you can’t afford to be without.
