Apple has released the second public beta for macOS Mojave. Announced at WWDC 2018, macOS 10.14 Mojave has a number of major new features including dark mode, desktop stacks, updates for Finder and Quick Look, new screenshot capture tool, and many more. You can try out all these new features by following our guide on how to download and install macOS Mojave public beta 2 on your Mac.
In terms of features and changes, the second public build is the same as macOS Mojave’s third developer release. If you already have macOS Mojave public beta installed on your Mac, go to System Preferences, Software Update to download the second public beta. This is Apple’s new system software update user interface in macOS Mojave. You don’t have to go to Mac App Store > Updates anymore to download system updates.
Apple had released the first developer beta for macOS Mojave on the same day as their developer conference. The developer beta is only available for registered Apple developers, which is a paid membership. However, anybody can register for Apple’s public beta and download it. Even though public betas are generally more stable than developer versions, please note that you might still run into issues so it is best to backup your data before continuing.
Check if your Mac is compatible with macOS Mojave
Apple dropped support for a number of Macs with Mojave. Here is a list of supported Mac models:
- iMacs, MacBook Pro, MacBook Air and Mac Mini models introduced in mid-2012 or later
- MacBooks introduced in 2015 or later
- 2010 and 2012 Mac Pro models and later, with recommended Metal-compatible graphics cards
- iMac Pro, 2017 and later
Backup your Mac!
Make sure to back up your Mac using Time Machine. You would need an external hard drive to use Time Machine. Connect it to your Mac, go to System Preferences > Time Machine and setup the drive as your backup device. The first backup might take a long time.
Download macOS Mojave Public Beta 2
- Go to Apple’s Public Beta Software Program website and login with your Apple ID.
- Once signed in your Mac, we will download the macOS Public Beta Access Utility which will be used to enroll your Mac in the public beta testing program. It should be available to download from this page. Once downloaded, run the pkg setup file and follow the instructions to proceed with installation.
- After you install the beta access utility, Mac App Store will open with the macOS Mojave download page. Start the download.
- Once you download completes, the macOS Mojave installer (also accessible from Applications folder) will open. From here onwards, follow the instructions to upgrade your Mac to Mojave. Your system might restart a few times and the installation might take a long time, so better grab some coffee.
Alternatively, you can also create a bootable macOS Mojave USB drive for a clean installation. The flash drive installer can also be used to install the public beta on another Mac, without enrolling it in the beta program.
Enjoy testing the public beta and don’t forget to share feedback with Apple, if you find any issues.
How to leave macOS Mojave public beta program
If you want to stop testing macOS Mojave, here is what you should do:
- Open System Preferences and click on Software Update.
- This is the new Software Update screen in macOS Mojave. Click on Details on the bottom left of the screen.
- Click on Restore Defaults to un-enroll your Mac from future beta updates.
This will not revert your Mac to a non-beta release of macOS. To downgrade, follow our guide on how to clean install macOS using Internet Recovery.
P.S. Apple has also released iOS 12 public beta 2 for iPhone and iPad.
