Apple today seeded the seventh beta of an upcoming macOS High Sierra 10.13.4 update to developers and public beta testers, one week after seeding the sixth beta and over a month month after the release of a macOS High Sierra 10.13.3 Supplemental Update to address a bug that could cause apps to crash when receiving a character from the Indian language Telugu.

The new macOS High Sierra 10.13.4 beta can be downloaded from the Apple Developer Center or through the Software Update mechanism in the Mac App Store with the proper profile installed.

macOS High Sierra 10.13.4 includes bug fixes and performance improvements for issues that weren't addressed in macOS High Sierra 10.13.3.

The update offers support for some features that are 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, and it includes support for eGPUs. Apple released release notes for macOS High Sierra beta 6 in certain countries, providing details on what's included in the update. The notes are below:
- Adds support for Business Chat in Messages in the U.S. and Canada
- Adds support for external graphics processors (eGPU)
- Fixes a graphical corruption issue affecting some iMac Pro apps
- Adds a keyboard shortcut for moving to the rightmost open tab in Safari by pressing Command +9
- Adds a feature for sorting Safari bookmarks by name or URL
- Fixes a bug that could prevent links from appearing in Messages
- Improves protection o confidential data by filling usernames and password fields in Safari only when selected
- Displays new warnings in the Safari Smart Search Field when interacting with forms that require credit card data or passwords on unencrypted web pages
- Displays more information on how personal data is used by certain features
The macOS 10.13.4 update also brings the smoke cloud wallpaper that was previously only available on the iMac Pro 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.

We're nearing the end of the macOS High Sierra beta testing period and a release could come any day now.

I haven’t seen the 32 bit app notification when running the beta and opening 32 bit apps. Anyone seen it? With what apps?
 
Does this mean ios 11.3 wont be ready for GM soon and have another beta?
 
Why not reinstall the previous version you had then?
I've considered it. Would at least take a full day. I'm a developer & unfortunately the amount of dev tools compatibility headache that goes into OS updates is a nightmare. This Macbook Pro has maxed out specs, cost a pretty penny. It's just a shame that a software based issue (driver) is making it perform terribly. This is the equivalent to iPhone speedgate issue (newer software purposely slowing down capable hardware), except with machines 3-4x the cost.
 
After applying this beta, my five external USB 3.0 drives take a very long time (several minutes) to mount upon login or wake. This did not occur with the last several 10.13.4 betas, although several 10.13.x betas have had issues with external drives not mounting or dismounting upon sleep.

Is it about graphics slowdowns?

Mine is quite the opposite - you might want to toss your drives through Disk Utility First Aid to make sure they are sound.
 
It seems it has been pulled, not showing up for me...

Update: I had to check for updates and install from the command prompt to get it to work.

I have a 2017 15" MBP that's still on Sierra, I want to upgrade to High Sierra but not sure if it will be better or worse.
 
It seems like this must be a regular beta. If it was a stopper then it would have lead to a release late last week. That suggests it won't be released this week but perhaps as late as week 2 of April, but that would be surprising for a length of a point release. To beta user hitting issues, this is the reason for betas.
 
I unfortunately made the mistake of upgrading and am highly regretting it.

I am with you. Apple's software quality control went from being one of the best, to where we are now, whcih is absolutely terrible.

I am absolutely dead set on not upgrading to 10.14 next year until it reaches 10.14.4 or even 10.14.5. The numerous problems with High Sierra have caused (and still cause) me a tremendous amount of pain. I cannot afford to trust Apple anymore and for the foreseeable future, I will remain one operating system behind the current times.
 
when was the last time a MacOS update underwent 7+ beta's?

It's happened before - doesn't strike me as unusual for a feature-heavy update. Most point releases are mainly bug fixes, but this one has official eGPU support which undoubtedly has some major driver and / or deep plumbing updates, plus cloud messages, a feature that is critical to get right.

What driver / dev tool is giving you issues? I'm still on Sierra, but I was thinking of upgrading to High Sierra in another point release or two.

That's pretty much been my MO for the last few releases. The new features in each new OS haven't been compelling enough for me to risk compromising my system's stability.
