Apple today seeded the fourth beta of an upcoming macOS High Sierra 10.13.4 update to developers, two weeks after seeding the third beta and two weeks 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, it replaces the "iBooks" app with the new renamed "Books" app, 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.

Update: Apple has also seeded a fourth beta of macOS High Sierra 10.13.4 for public beta testers.

We live in an SSD world now.

Antiquated, compromised tech - like fusion drives - are not long for this world. While Apple may support APFS for fusion drives by 10.13.5. or 10.13.6, the real question is why would you even think it would make a difference?

If you want to really make a difference, bite the bullet and get a 1tb or 2tb SDD, wash your hands of spinning drive tech forever ... and walk away. :)
2TB? Too small. 8 TB, please. :)
But really, for storage of lots of data (for a reasonable amount of money) SSDs still have a way to go it seems.

Prohibitively expensive? Who you kidding? A few years ago a 2tb ssd was about $4000, now its $450 or so. For the speed and endurance you get - thats incredibly afforable. Especially for a Mac guys (like we are) who spend 2k on our computers.
But sometimes you don't need the speed, but rather the capacity. A family may not be able to store their entire photo and video library on SSDs because it'd be prohibitively expensive to do so, and because the speed benefits would be near-irrelevant for archival purposes. Similarly, SSDs are a poor fit for backup.

Just an observation: the Books app has been removed from macOS 10.13.4 beta 4 and iBooks is back.

I suspect this is a temporary situation while fixing some bug with the Books app.
Maybe they're waiting to announce some change to the book store.

Don't think so, people were complaining about searching for books in Books instead of iBooks, you get irrelevant information when using the word books instead of iBooks.
Could they change Photos back to iPhoto for that reason
