Apple today seeded the sixth beta of an upcoming macOS High Sierra 10.13.4 update to developers, one week after seeding the fifth beta and one 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.

macoshighsierra10134beta
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 improved support for eGPUs.

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.

It’s a beta update to a minor release. No big news.

I asked this very question in the previous 10.13.4 beta release thread and never got a good answer. I wish you better luck.
Nobody outside Apple knows.

Can you imagine if Ford or Toyota said this?
"Sorry, you cannot use these tires on this car anymore. The last repair to your car made them inoperable.
But you're still free to drive the car."

No, but what I can imagine is another tired car analogy.

By the way, good luck using all features on your car entertainment system if it’s more than a few years old. Same reason.

"Without compromises" - what does that mean, exactly?

And yet, every minor beta iOS release gets featured on the main page.
You beat me to it and you are absolutely correct. Does Macrumors consider macOS to be of any importance if not it should be renamed iOSrumors as there is now primarily iOS content or blanket coverage of any other Apple device such as the HomePod.

Macrumors has lost focus and direction to the extent that the Mac user needs to go searching for articles of interest.

That’s because no one here knows, and Apple is being deliberately vague. My guess (!), though, is that the first “compromise” will be the dropping of Carbon support, which is long-deprecated.
