Apple today seeded the first beta of an upcoming macOS Sonoma 14.5 update to public beta testers, allowing non-developers to test the software ahead of its launch. The public beta comes a day after Apple released the developer beta.
Beta testers can opt-in through the Software Update section of the System Settings app. Under Beta updates, simply toggle on the Sonoma Public Beta. Note that you must sign up to participate on Apple's beta testing website.
There were no new features found in the macOS Sonoma 14.5 developer beta, and Apple listed no additions in its release notes. It is likely that the update focuses on bug fixes and other small under-the-hood improvements.
