Apple Seeds Fifth macOS High Sierra 10.13.1 Beta to Developers [Update: Public Beta Available]

by

Apple today seeded the fifth beta of an upcoming macOS High Sierra update to developers, three days after releasing the fourth macOS High Sierra 10.13.1 beta and a month after releasing the new High Sierra operating system to the public.

The fifth macOS High Sierra 10.13.1 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 10.13.1 focuses primarily on bug fixes, performance improvements, security enhancements, and other under-the-hood changes.

The update includes a fix for a serious vulnerability in the WPA2 Wi-Fi standard that protects many modern Wi-Fi networks. Using a key reinstallation attack or "KRACK," attackers can exploit weaknesses in the WPA2 protocol to decrypt network traffic to sniff out sensitive information. This attack is not possible with the patch in macOS 10.13.1.

Also new in macOS 10.13.1 is a range of new Unicode 10 emoji like crazy face, pie, pretzel, t-rex, vampire, exploding head, face vomiting, shushing face, love you gesture, brain, scarf, zebra, giraffe, fortune cookie, pie, hedgehog, and more. The new emoji are also available in iOS 11.1 and watchOS 4.1.

macOS High Sierra is a major update that introduces APFS, a new more modern file system, HEIF and HEVC photo and video encoding improvements for smaller file sizes without compromising quality, Metal 2, and several new features for Safari, like autoplay blocking for videos and Intelligent Tracking Prevention to better protect user privacy.

Update: Apple has also released a new beta of macOS High Sierra 10.13.1 to public beta testers.

I know youre being sarcastic, but the only ‘bug’ they mention being fixed is the wifi security issue. And they mention the emojies.
It would be nice to hear what else they are focused on.
Plus, theres been zero info on when apfs support might actually come to fusion drives.
it would be nice for people to actually read the articles and realize when these betas are released there is no idea right away at what's being fixed. The articles are mainly cut and pasted and describe, in general, what the software release contains from the get go.

these 'oh my god, why are they just working on emojis' comments stopped being funny in June

Given the hoopla that they made of APFS, it seems that they sure screwed the pooch in announcing it,
Given that they successfully shipped APFS to hundreds of millions of iOS devices without issue, that seems a strange assessment.


long before they had a clue as to what was involved in getting it ready for a Beta release, let alone a GM release. Perhaps they should have done the "One More Thing" teaser with APFS, and announce it for next year?
APFS is out. Tons and tons of iOS devices run it. And the vast majority of Macs on High Sierra do, too.

Seriously, after this long, and they still don't have it working on Fusion drives? How many Macs did they sell, that have Fusion drives?
Surely quite a minority.

I also don't see the problem. They pulled APFS Fusion Drive support in 10.13.0 last-minute because they weren't happy with the reliability. It doesn't really affect users with a Fusion Drive at all, because they simply continue to use HFS+ just as before. They'll eventually get upgraded. Just not today.

Not sure whom you mean by "they" — MacRumors isn't Apple's PR department, and while MacRumors's beta articles always strike me as a little misleading (no, the main focus of 10.13.1 is not to deploy emoji, nor is it to fix the Wi-Fi bug — several betas existed before the Wi-Fi bug was discussed), Apple does provide release notes. Which don't mention the emoji at all, because that really isn't the point of the developer betas. The main purpose of the developer betas is to test whether your apps still work. That's why the release notes mention, among other things, what they already know does not work, so you don't bother testing that part. And the mention changes in behavior, so you know to focus particular on that. And so forth.

It would be nice to hear what else they are focused on.
It would — tell Apple that?

Plus, theres been zero info on when apfs support might actually come to fusion drives.
Not looking like that'll make it to 10.13.1. The update does include changes to Disk Utility, diskarbitrarion, etc., though, so maybe they're making preparations for that.

Does this fix the bug where the Mac mini hasn’t been updated in 1106 days?

C’mon Apple make the Mac mini great again.
