Apple Seeds Second Beta of macOS High Sierra 10.13.5 to Developers

Apple today seeded the second beta of an upcoming macOS High Sierra 10.13.5 update to developers, two weeks after seeding the first beta and three weeks after releasing the macOS High Sierra 10.13.4 update.

The new macOS High Sierra 10.13.5 beta can be downloaded through Apple Developer Center or the Software Update mechanism in the Mac App Store with the proper profile installed.

macoshighsierra10135beta
macOS High Sierra 10.13.5 introduces support for Messages on iCloud, a feature that was previously present in macOS High Sierra 10.13.4 betas before being pulled ahead of the release of the update. Messages on iCloud is also available in iOS 11.4.

The update also likely includes bug fixes and performance improvements for issues that weren't addressed in macOS High Sierra 10.13.4, but as Apple does not provide detailed release notes for macOS High Sierra updates, we may not know exactly what's included until the new software is provided to the public.

No major outward-facing changes were found in the first beta of macOS High Sierra 10.13.5, but we'll update this post should any new features be found in the second.

The previous macOS High Sierra 10.13.4 update brought support for external graphics processors (eGPUs) along with Business Chat in Messages and several other bug fixes and smaller feature improvements.

I wish they would post the areas of focus on these like they used to.

Worth the update from Sierra, or still have issues?
My thoughts exactly. Running an old mid-2010 MacPro 12-core, with an SSD plus two HDs for storage and backups. All apps behaving themselves, pretty much, with an Nvidia GTX980Ti GPU. I'm usually all over OS upgrades, but this one seems a bit dodgy for older machines. Do the benefits outweigh the risk?
It's a beta. The second beta. Of course it has issues.
If you realy want to upgrade from Sierra to High Sierra, upgrade to the latest stable version MacOS 10.13.4.

10.13.4 had a major issue with multiple display support, and it’s rendered Duet Display for my iPad Pro unusable. The Duet support guy admitted that it broke because Apple hardcoded the resolutions in 13.4, which their team now is (unsuccessfully so far) trying to fix. Apple support of course is mum on this, and Duet cannot give an ETA for a fix.

I haven’t been so frustrated about something so seemingly basic in a long time. iCloud Messages can wait IMHO, as long as Apple does some SERIOUS debugging on their trainwreck OS and stop “fixing” things that aren’t broken.

I'm not upgrading until they let me use Nvidia cards in my eGPU. This feud of theirs is hurting me as an artist and it makes me real mad.
