Apple today seeded the first beta of an upcoming macOS High Sierra 10.13.4 update to developers, one day after releasing the macOS High Sierra 10.13.3 update focusing on security improvements.

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.

It's not yet clear what improvements the fourth official update to macOS High Sierra will bring, but it's likely to include bug fixes and performance improvements for issues that weren't addressed in macOS High Sierra 10.13.3. It may also include some of the features that are coming in iOS 11.3, such as support for Business Chat and unlimited ad-free access to music videos in Apple Music, which Apple says will be the new "home" for music videos.

According to Apple's release notes, macOS High Sierra 10.13.4 will begin sending warning notes when you open up a 32-bit app in preparation for phasing out 32-bit apps on the Mac. At this time, you'll see one warning letting you know that a Mac app is 32-bit, and it will popup when you open the app after installing the macOS High Sierra 10.13.4 update.

macOS High Sierra 10.13.4 also introduces the new smoke cloud wallpaper that was previously exclusively available on the iMac Pro.

The previous macOS High Sierra 10.13.3 update included security fixes and performance improvements, with no obvious outward-facing changes introduced.

Well, Preview is screwed up. Displays images as scrambled.

Also noticed something new after installing like below.

Build number is 17E139j.

You can disable the 32 bit apps like this in terminal:

Boot to Recovery OS by restarting your machine and holding down the Command and R keys at startup.

Now in terminal use this:

nvram boot-args="-no32exec"

Then restart computer.

You can re-enable them like this:

nvram boot-args=""

(again in Recovery OS)

Then restart computer.



Looks like there will cease to be separate special builds for the iMac Pro now. They can use the same installers (including combos) the other macs can use for 10.13.4. Previously for 10.13.3 betas and the final release of 10.13.3 the iMac Pro got their own special builds and no combo.

The 10.13.4 installer also now has a new component called Secure Boot:



EDIT: The commands for enabling and diabling 32 bit apps have been corrected thanks to GDP3.

Same issue although I'm just getting a blue box when using preview. Has no one else noticed this?

Still no APFS on Fusion Drives? They're having quite some difficulty with that. :/

Same thing going on here, and I too am running an old version of iStat Pro haha. I hope that doesn't go way.
Yeah - I like having it in Dashboard, and I'm a cheapskate who doesn't want to pay for iStat Menus :P.
But if it goes I'll be fine. I'll just use htop for my quick system overview, and MacsFanControl for sensor readings.

I remember the days when there were reasons to be excited about macOS releases. Even the lowly tvOS got new features, but the Mac just gets maintenance mode now.
