macOS Sierra Auto Unlock teaser 002

If you’re signed on the Apple Beta Software Program, you can now install the latest beta of macOS Sierra on your Mac even if you’re not a developer as macOS Sierra Public Beta 3 just went live minutes after the Cupertino firm posted the third public beta of iOS 10.

macOS Sierra Public Beta 3 contains the same features as the developer-only macOS Sierra beta 4. Developer-only fourth betas of iOS 10, macOS Sierra, watchOS 3 and tvOS 10 were pushed yesterday.

If you run a prior Sierra beta, are enrolled in Apple Beta Software Program and have a proper configuration file installed on your computer, the latest public beta of Sierra should appear under the Mac App Store’s Updates tab.

The third public beta of macOS Sierra—and developer-only beta 4—are light on new features as Apple continues squashing bugs and smoothing out the rough edges.

Release notes for macOS Sierra Public Beta 3 are available from Apple.

Apple currently offers public betas for iOS and macOS.

Everyone else will have a chance to install Sierra on their Macs when the operating system launches this fall as a free software update on the Mac App Store.

      Not much point in a beta at all. Extremely stable though.

    • Luke Rinehart

      You obviously can’t read release notes/change logs

      • john snow

        i am not talking about changes between 10.11 and 10.12. I mean changes between beta 2 and beta 3.

    • Antonio Perez

      do you have a mac? there are many new adware and spyware in w10 as usual.

      • john snow

        i have a mac. i have a 6S. I’m testing both Sierra and iOS 10.
        iOS 10 have significant changes in every beta while macOS has no changes that i can see

    there are many new features , but a minute and a half is not enough time to show everything , you need to see a 20 minutes long video in you tube or install the beta and find out for yourself. i’m just waiting for the official release version of sierra , i already install sierra on my system so i already know is supported. after that i deleted and went back to EC.

    For people with machines from 2010 ,a general fix after updating,go to Disk Utility and fix the permissions,did wonders for the 4 Macs I did the update on,spread the word.This also fixes a lot of the UI messups

    Public Beta 3 is a complete turd. Beta 2 was fantastic, but 3 reintroduces the beach ball and launch crashes of pretty much all of the native system apps. Boot -up is now twice as long as the OS seems to have forgotten how to initiate itself. Even with 16g of RAM and a 1T SSD on my MacBook Pro means nothing. I find it rather odd that a successive beta could get worse than the previous. Beta 3 for iOS works just fine, but not macOS beta 3.


    Just can’t update to PB3 I’m stuck with calculating and sometimes at 0kb forever HELP!
