Apple announced macOS Mojave, the latest version of their desktop operating system, at WWDC 2018. This new major update will ship with updates like dark mode, desktop stacks, updates to Finder and Quick Look, new screenshot tool, new Stocks, News, Voice Memos and Home apps, dynamic wallpapers, redesigned Mac App Store and a bunch of privacy and security enhancements. macOS 10.14 is currently in developer testing, while a public beta is expected by the end of June. If you have an Apple developer account or are interested as an enthusiast, here is how you can download and install macOS Mojave developer beta on your Mac and test the new features.
The new update is around 2.25 GB in size. If you already have macOS Mojave developer beta installed, go to System Preferences > Software Update to download beta 11. Otherwise, follow our guide to download and install it to your Mac.
Before we start, make sure that you backup your Mac. The best way to do this is to use Time Machine, which is a built-in Mac feature. You would need an external hard drive with capacity equal to or more than your Mac’s storage. Connect it to your Mac, go to System Preferences > Time Machine and select it as your backup disk. The first backup always takes the longest so it is best to do this when you don’t need to use your Mac.

- Now that we have the mandatory backup out of the way, it’s time for the fun stuff. The first step: sign up for an Apple Developer account. This will cost you $99/year. If you do not want to spend the money, you can download the macOS Mojave beta access utility from here.
Once logged in, head over to Downloads and look for macOS Mojave 10.14 beta. Download the beta access utility to your computer.
- Open the macOS Developer Beta Access Utility DMG file and run the pkg file inside. This is an installer that will enroll your Mac to receive developer beta updates. Launch this installer and follow the instructions.
- Once the installation completes, it will open Mac App Store’s page for macOS Mojave. Start the download. It might take a while as the installer is around 4.90 GB in size.
- After download completes, the installer for macOS 10.14 Beta will automatically launch. Follow the instructions as per the screenshots below to start the install process. Your Mac might restart a few times during the installation and it might also take a long time so make sure that your Mac (if portable) is plugged in to an outlet and not on battery power.
Once the process completes, you should be greeted with the setup screens, including the new screen for choosing the dark theme. Make sure to check out the new dark theme, which can be later changed again from System Preferences > General.
Don’t forget to give your feedback on the new features and on any issues that you might face during beta testing. It not only helps Apple in fixing issues before the final release, it also helps them understand user reaction to new features and tweak them as necessary.

If you want to do a clean install or install the beta on multiple Macs, you can also create a bootable USB installer for macOS Mojave. Apple is also beta testing iOS 12. Check out how you can download and install iOS 12 developer beta.
