MacOS High Sierra 10.13.3 Beta 1 Released for Testing

macOS High Sierra beta

Apple has released the first beta build of macOS 10.13.3 High Sierra to users enrolled in the beta testing program for the Mac operating system.

The macOS High Sierra 10.13.3 beta 1 release focuses on bug fixes, enhancements, and other improvements to the MacOS High Sierra release.

Though not specifically mentioned, it’s possible some of the lingering issues reported with macOS High Sierra will be addressed in the 10.13.3 version.

Users who are enrolled in the Mac beta testing program can find the macOS High Sierra 10.13.3 beta update available now via the Mac App Store Updates tab.

Anyone can enroll to participate in the public beta testing programs for macOS and iOS, but doing so is generally not recommended as beta software is notoriously unreliable as the bugs and quirks are worked out during the development process. Additionally, anyone can sign up to participate in the Apple Developer beta testing program, though unlike the free public beta, the Apple Developer program requires an annual $99 fee for access. The Apple Developer program also allows for users to submit apps to the App Store, however.

The freshly released macOS 10.13.2 update is currently the most recent final build available for MacOS High Sierra users, and Mac users running prior system software will find security updates available for El Capitan and Sierra.

Presumably an iOS 11.3 beta 1 update will be released soon for iPhone and and iPad beta testers as well.

Apple typically goes through several beta builds before releasing a final public version, suggesting that macOS 10.13.3 could be reasonably expected to be released for the general Mac using public sometime in the early months of 2018.

    A hello to the OS X Daily and the visitors of this website,

    – Is there anyone who install the latest version of high sierra (10.13.2) to an older machine?
    (ex. iMac Late 2009 / i7 2.8Ghz)
    – Any remark(s) or a thorny critical issue with speed for instance? – Slower or.. what?
    – The APFS system has support for the time machine from now on?
    – What If I have external drives with some useful, very important content? Should I convert them to the APFS or not?

    Thank you very much for your special time and for your very useful articles!

      Personally I do not recommend installing macOS High Sierra *at all* on *any Mac*, I find it to be the worst Mac system software release in ages. I do not recommend it to anyone unless they like beta buggy software. I use Sierra 10.12.6 and it is stable, reliable, and works great.

      I will reconsider High Sierra at 10.13.5 but nothing before, I just do not trust it. As for APFS, I think it is a mess too. I would avoid until they are done beta testing the whole thing, it is clearly all still in beta and has problems galore. That’s my experience anyway, but you can make your own decisions.

      If you like the way your Mac runs now, why break it trying to install beta software?

        Thank you for your feedback / reply.
        – Yes, almost I agree with you.
        – Right now I have installed the 10.11.6 (El Capitan). Always and each time that new release coming of a new OS always I wait for the next at least two or three versions/updates. I have to format my drive because last time was before two years. So it’s an immersive needing because I have lots of unnecessary things installed (like as previous versions of Adobe software ) and I am thinking to update the mac to the latest version of OS.
        – I have already build a separate partition into my main hard drive, I have formatted it as APFS and I have installed the OS High Sierra to see how it looks and which is the behaviour as OS and what’s going on with the memory usage.
        – When I would be completely sure after next two updates I will give a try.Until now, and after some critical tests, it looks to me that works properly, it is stable and reliable. Functions / features such as mission control, notification center, notes, photos or the mail not only looks better but working better.
        – Of course, I do not have a complete opinion, so this is the reason that I am staying with El Capitan yet. And If the test finally failed, then yes I install the OS Sierra.
