Apple has released the fourth public beta for macOS Mojave. The new versions follows the release of macOS 10.14 Mojave developer beta 5 which was released yesterday. macOS Mojave has new features like a system-wide Dark Mode, updates for Finder and Quick Look, desktop stacks, a new screenshot capture tool, and more.
Some of the new features found in the new release include a number of new wallpapers, as well as an option to enable/disable external eGPU support per application.
The fourth public beta is the same as macOS Mojave’s fifth developer release. If you are already on an existing public build, go to System Preferences > Software Update to download the new public beta.
While developer betas are only available for registered Apple developers, anybody with a Mac can register for Apple’s public beta program. If you are not part of Apple’s public beta program, read on to find out how to register and download Mojave beta on your Mac.
Is your Mac compatible with macOS Mojave?
With macOS Mojave, a number of older Macs have reached end-of-life for macOS updates. This is the list of Mojave 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
It is very important to back up your Mac using Time Machine. To do so, you need an external hard drive to setup and use Time Machine. Connect the external drive to your Mac, go to System Preferences > Time Machine and select it as your backup disk. The first backup might take a long time so you might need to wait for a few hours.
Download macOS Mojave Public Beta 4
