Apple today seeded the fifth beta of the upcoming macOS Big Sur update to developers for testing purposes, two weeks after releasing the fourth beta and over a month after the new update was unveiled at the Worldwide Developers Conference.
The macOS Big Sur beta can be downloaded through the Apple Developer Center and once the appropriate profile is installed, subsequent betas will be available through the Software Update mechanism in System Preferences.
