Apple Seeds Second Beta of macOS High Sierra 10.13.4 to Developers

Apple today seeded the second beta of an upcoming macOS High Sierra 10.13.4 update to developers, two weeks after seeding the first beta and two weeks after releasing macOS High Sierra 10.13.3.

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 includes 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, 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.

This release also has a lot of goodies for eGPU owners. We can now attach remove the egpu without a logout. Also clamshell mode is now supported. Looking forward to the final version to install on my production computer.

I’ve heard this is the release that makes MacOS solid. Yes, still bugs as there will always be, but the release that isn’t brand damaging and the one Apple should have released.

Clearly, Apple needed another four months—plus even more time to finish the other features.
What are you on? I need some. ;-)

When MacOS 10.13.3 came out, we upgraded 3 MacBook Pro's (2 x 15 inch retina 2012 and one 2014 13 inch). All MacBooks experienced a mayor drop down in performance. It was like thick sirup against the wind running uphill. We all downgraded to Sierra and got our performance back. So my advice? Do not upgrade 'older' Macs. I really hope High Sierra or it's successor wil have way better performance...
I think it always depends on the specific machine. Since the window server is now Metal2 instead of OpenGL I got a huge performance boost with High Sierra.

They actually did rewrite a significant amount of under the hood code between Sierra and High Sierra.
If they hadn’t, they’d be accruing more and more technical debt. You can’t just keep piling on.

I know it’s hip to hate on discoveryd, but the fact that it was ultimately reverted may be a bad sign for the long-term
quality of Bonjour. They couldn’t make a rewrite work, so they had to tack Continuity (Handoff, AirDrop, etc.) on to the existing core, which is now a decade and a half old. That’s not so great. And guess where I do have flakiness? In Continuity.

It's interesting, have they fixed "black boxes" bug with Intel HD cards and non-default ICC profiles?
I truly believe they should stop releasing new version of OS every year. They just have lack of resources to polish it good enough.

can anyone tell me whether there’s any reason to upgrade to HS yet?

I had a 2016 MBP and I upgraded it to 10.13.1, which was a hot mess. There were all sorts of instability issues, finder slowdowns, just general ugliness. But then I sold that machine, downgraded to a 2015 MBP, which came with Sierra on it. I haven’t upgraded back to HS because my earlier experience was so awful.

Again, serious question here: 10.13.1 was awful. Is it at all compelling as an upgrade yet?
