Since the Beta Software Program is open to anyone who wishes to sign up, it\u2019s easier to think of this as a public beta for anyone whose <a href=\"https:\/\/eshop.macsales.com\/shop\/Apple_Systems\/Used\/Macs_and_Tablets\">Mac<\/a> meets the <a href=\"https:\/\/eshop.macsales.com\/blog\/44862-a-complete-list-of-mojave-compatible-macs\" target=\"_blank\">minimum requirements for using macOS Mojave<\/a>.<\/p>\n<p>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.<\/p>\n<p>To pique your interest, we started off with <a href=\"https:\/\/eshop.macsales.com\/blog\/44944-whats-new-in-macos-mojave-a-first-look-at-the-developer-beta\" target=\"_blank\">What&#8217;s New in macOS Mojave: A First Look at the Developer Beta<\/a>.<\/p>\n<p>The follow-up article described <a href=\"https:\/\/eshop.macsales.com\/blog\/45008-how-to-get-your-mac-ready-for-the-macos-mojave-beta\" target=\"_blank\">How to Get Your Mac Ready for the macOS Mojave Beta<\/a>.<\/p>\n<p>And that leaves this article, which covers how to perform the actual install of the macOS beta.<\/p>\n<p><strong>Developer or Public Beta of Mojave?<\/strong><br \/>\nApple developers already have access to the beta of Mojave, and since the public beta isn\u2019t quite available yet, we\u2019re 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\u2019t 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\u2019s 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.<\/p>\n<p><strong>How Many Ways Are There to Install the macOS Mojave beta?<\/strong><br \/>\nMore than you might think, but we\u2019re going to look at two primary methods: the upgrade install and the clean install.<\/p>\n<ul>\n<li><strong>Upgrade Install:&nbsp;<\/strong>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.<\/li>\n<li><strong>Clean Install:&nbsp;<\/strong>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\u2019t recommend using this install method on your Mac&#8217;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.<\/li>\n<\/ul>\n<p><strong>Back Up, Please<\/strong><br \/>\nBefore 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&#8217;t afford to be without.<\/p>\n<p><strong>Time to Install<\/strong><br \/>\nThe upgrade and clean install processes are, remarkably, the same for installing the beta of macOS Mojave. This is because, for a beta install, we\u2019re not targeting your Mac&#8217;s startup drive for a clean installation. If we were, the clean install process would be quite different, with a number of additional steps, including creating a bootable Mojave installer, starting up from the bootable installer, and erasing the startup drive.<\/p>\n<p>Instead of targeting the startup drive for the install, this guide assumes you\u2019ll be installing on an external drive, a second internal drive, or possibly a volume contained on a drive you partitioned.<\/p>\n<p>One last reminder: before you install, make sure you have current backups.<\/p>\n<p><strong>What&#8217;s Needed for a Beta Install<\/strong><\/p>\n<ul>\n<li>You need a volume with enough space to hold a clone of your current startup disk (upgrade install), or enough free space for a clean install of the Mojave beta (40 GB or larger is adequate for beta testing space). This can be an <a href=\"https:\/\/eshop.macsales.com\/shop\/external-storage\" target=\"_blank\">external<\/a>&nbsp;or <a href=\"https:\/\/eshop.macsales.com\/shop\/internal_storage\/hard_drives_and_SSD\" target=\"_blank\">internal<\/a>&nbsp;volume, and will eventually house the Mojave beta.<\/li>\n<li>For an upgrade install, you\u2019ll also need a cloning app to create a copy of the startup drive. You can use Carbon Copy Cloner, SuperDuper, or even Disk Utility for this function.<\/li>\n<li>Last but not least, a copy of the beta macOS Mojave installer app, available through the <a href=\"https:\/\/developer.apple.com\/programs\/\">Apple Developer Program&nbsp;<\/a>or the <a href=\"https:\/\/beta.apple.com\/sp\/betaprogram\/\">Apple Beta Software Program<\/a>.<\/li>\n<\/ul>\n<p><strong>Upgrade Install Method<\/strong><br \/>\nLet\u2019s kick off the install process with the method most likely to be used: the upgrade install. This is the method Apple expects most of us to use when the full release of macOS Mojave is made available later this fall.<\/p>\n<p>Our version of the upgrade install is slightly different since we don\u2019t want to upgrade our Mac&#8217;s startup disk. Instead, we\u2019re going to clone the startup disk to an external disk and use the external as the target for the upgrade install.<\/p>\n<figure id=\"attachment_45051\" aria-describedby=\"caption-attachment-45051\" style=\"width: 640px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-45051\" src=\"https:\/\/eshop.macsales.com\/blog\/wp-content\/uploads\/2018\/06\/CloneStartup640.jpg\" alt=\"\" width=\"640\" height=\"447\" srcset=\"https:\/\/eshop.macsales.com\/blog\/wp-content\/uploads\/2018\/06\/CloneStartup640.jpg 640w, https:\/\/eshop.macsales.com\/blog\/wp-content\/uploads\/2018\/06\/CloneStartup640-172x120.jpg 172w, https:\/\/eshop.macsales.com\/blog\/wp-content\/uploads\/2018\/06\/CloneStartup640-284x198.jpg 284w, https:\/\/eshop.macsales.com\/blog\/wp-content\/uploads\/2018\/06\/CloneStartup640-190x133.jpg 190w, https:\/\/eshop.macsales.com\/blog\/wp-content\/uploads\/2018\/06\/CloneStartup640-172x120@2x.jpg 344w, https:\/\/eshop.macsales.com\/blog\/wp-content\/uploads\/2018\/06\/CloneStartup640-284x198@2x.jpg 568w, https:\/\/eshop.macsales.com\/blog\/wp-content\/uploads\/2018\/06\/CloneStartup640-190x133@2x.jpg 380w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><figcaption id=\"caption-attachment-45051\" class=\"wp-caption-text\"><strong>(The upgrade install will target a clone we made of our startup drive.
