Apple Seeds Third macOS High Sierra 10.13.1 Beta to Developers

by

Apple today seeded the third beta of an upcoming macOS High Sierra update to developers, a little over a week after releasing the second macOS High Sierra 10.13.1 beta and nearly a month after releasing the new High Sierra operating system to the public.

The third 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 appears to focus on bug fixes, performance improvements, security enhancements, and other under-the-hood changes, but it also introduces 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.

Safari have bug, new tab and click any link in bookmark ( favourite). Freezer and lag. Please see and fix.
Who are you talking to? This is a beta. If you have a problem, use the Feedback app installed in the Dock and send you complaint to Apple.

It's kind of amazing the things they can break in such minor updates. o_O
It's a minor update to a major BETA! Things are SUPPOSED to be broken. If you run a beta OS, it's your job to find the bugs and report them.

Still nervous about upgrading from Sierra on a mid-2015 rMBP 15 (MJLT2LL/A).

I'm having a lot of trouble with external monitors and crashes while the computer is on sleep mode. Reinstalled twice, problems persist. MacBook Pro (Retina, 13-inch, Early 2015) / Thunderbolt Display / High Sierra 10.13
Same. High Sierra runs great until I start using external monitors. The UI goes weird and the OS eventually crashes. After rebooting it works fine.

You are aware CDN's are also subject to DNS propagation, right?
DNS propagation of what? Why would there be any new DNS entries here? It's a blob of data that's being propagated through a CDN. Nothing to do with DNS.

Well that was snappy.

Still no Mac Blu-Ray player though.
Also in other news of never-gonna-happen, no PowerBook G5.
