Apple today released the third beta of an upcoming macOS High Sierra 10.13.4 update to public beta testers, one day after seeding the third beta to developers and two weeks after releasing the second 10.13.4 public beta.

Beta testers who have signed up for Apple's beta testing program will be able to download the new macOS High Sierra beta through the Software Update mechanism in the Mac App Store.

Those who want to be a part of Apple's beta testing program can sign up to participate through the beta testing website, which gives users access to iOS, macOS, and tvOS betas.

macOS High Sierra 10.13.4 introduces support for some features that are also available in iOS 11.3, like Messages on iCloud, which uploads all of your iMessages to the cloud. It will also support Business Chat, a feature coming when iOS 11.3 and macOS 10.13.4 are released to the public.

The new macOS update also includes the smoke cloud wallpaper that was previously only available on the iMac Pro, it changes the name of the "iBooks" app to just "Books," and it introduces a warning when opening up a 32-bit app as part of an effort to phase them out.

In the future, Apple plans to phase out 32-bit Mac apps, just like it did with 32-bit iOS apps. Apple says macOS High Sierra is the last version of macOS that will support 32-bit apps without compromises.

I’m unable to get the update to show up in the App Store. Tried installing the public beta and dev beta profiles several times... Has anyone experienced this and/or has a solution?
Are you already on a beta, or an official release?
Had the same thing happening coming from 10.13.3. This was the first of the 10.13.4 betas that I wanted on my machine, but upon enrolling, installing the utility, and checking for updates, nothing. Tried all sorts of different things and the only thing that worked was to reinstall High Sierra from recovery. Crazy.

there's a reason it's called beta, right
But...the issue was on an official release, not a beta.

is it identical to the latest Developer beta?
First comment on the developer article was the build number:

Same build.

Well, if someone was hammering the update server, Apple may just have a backoff (ie ignore) option in there.

If people are changing their catalog in terminal, if they have a type-o in the catalog, they won't get the update.

Developer Catalog URL: https://swscan.apple.com/content/catalogs/others/index-10.13seed-10.13-10.12-10.11-10.10-10.9-mountainlion-lion-snowleopard-leopard.merged-1.sucatalog.gz

Beta Catalog URL: https://swscan.apple.com/content/catalogs/others/index-10.13beta-10.13-10.12-10.11-10.10-10.9-mountainlion-lion-snowleopard-leopard.merged-1.sucatalog.gz

sudo /usr/sbin/softwareupdate --set-catalog URL

Me, if I wasn't getting the update, I'd set it back to production, leave it for an hour, then set it back to beta and check for an update.

Edit: Oh, and per Beta 3 - nice to see that they fixed the problems with Amazon Prime Video playback in Safari.
