Apple Releases Second Beta of macOS High Sierra 10.13.5 to Public Beta Testers

Apple today released the second beta of an upcoming macOS High Sierra 10.13.5 update to public beta testers, two weeks after seeding the first beta and three weeks after releasing macOS High Sierra 10.13.4. Today's public beta is identical to the second beta provided to developers earlier this week.

Beta testers who have signed up for Apple's beta testing program will be able to download the new macOS High Sierra beta through the Software Update mechanism in the Mac App Store.

Those who want to be a part of Apple's beta testing program can sign up to participate through the beta testing website, which gives users access to iOS, macOS, and tvOS betas.

macOS High Sierra 10.13.5 once again introduces support for Messages on iCloud, a feature that was present in macOS High Sierra 10.13.4 betas but pulled ahead of the release of the updated software.

Messages on iCloud is designed to store your iMessages in iCloud for improved syncing. Right now, incoming iMessages will be sent to all devices where you're signed into your Apple ID, but it's not true cloud-based syncing because your old messages don't show up on new devices nor does deleting a message remove it from all of your devices, both features enabled through Messages on iCloud.

The Messages on iCloud feature also allows your older iMessages to be stored in iCloud rather than on your iPhone, iPad or Mac, saving valuable storage space. Older attachments are also stored in iCloud.

No other major outward-facing changes were discovered in the first two developer betas, but the update likely includes bug fixes and improvements to address issues discovered since the release of macOS High Sierra 10.13.4. Because 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.

If you still haven't updated to High Sierra, DON'T. Sierra was a better OS, and there are no real benefits with High Sierra (unless you want to use an eGPU). It's basically the same system with a new slower file system (vs HFS), startup and overall response is slightly slower, there are various bugs depending upon which Mac model you use etc...etc... The latest 10.13.4 update made things worse, not better (introduced new bugs with both my iMac Pro and MacBook). This is like walking backwards into the future.

I have the latest HS on my mid 2010 mac pro and it is the stablest OS so far for my computer. I was on sierra but I was getting system freezes that multiplied after the security updates. There has not been one system freeze or crash since updating to HS 10.13.4

Same here. High Sierra on a 2010 Mac Pro is a rock.
On a 2016 Touchbar MacBook Pro with LG 5K screen, not so much. It crashes a lot.

You said HS has been crap. I gave an example of a specific HS-only feature saving me several hundred pounds.
Ok, fair. We have completely different usage scenarios, and I admit I had overlooked this feature.

Speaking from the shoes of a designer working with multiple displays and I/O means, High Sierra (and the new MBP) have offered me nothing but setbacks.
